Cold-Chain 3PL · Costa Mesa, CA · Research Use Only
Peptide 3PL & Fulfillment, From the Manufacturer
Most 3PLs rent you shelf space and hope the manufacturer upstream ships on time. We are the manufacturer. Your inventory is held in −20°C or 2–8°C storage, picked, packed, and shipped from the same US facility that produces and labels it — temperature monitored, lot-tracked end to end, going out under your brand. One account manager owns production and fulfillment, so a restock is an internal transfer instead of a purchase order.
Research Use Only
All products are intended solely for laboratory research purposes and are not for human or animal consumption. Must be handled by qualified professionals.
Three ways to get orders out the door
Self-fulfillment, a general 3PL, or fulfillment run by the company that made the product. They fail in different places — and the differences only show up once something goes wrong.
| Criterion | Doing it yourself | A generic 3PL | Manufacturer-integratedWhat we run |
|---|---|---|---|
| Restock lead time | Whatever your supplier quotes, plus your own receiving time | Supplier lead time + inbound freight + 3PL receiving queue | Internal transfer — no inbound freight lane, no second receiving step |
| Who is accountable for a bad lot | You are, and you chase the manufacturer | Unclear — manufacturer and 3PL each point at the other | One party. We made it and we shipped it |
| Lot continuity | Depends on your records | Re-established at receiving, from whatever paperwork arrives | Never broken — the lot record starts at production |
| Temperature control | A consumer freezer and hope | Often ambient only. Where cold exists, ask to see the logs | −20°C and 2–8°C zones, temperature monitored, logs on request |
| Peptide-specific handling | Yours to figure out | Varies wildly. Most warehouses have never handled a vial | Same handling discipline as our own production stock |
| Cost at low volume | Cheapest — your time is the hidden cost | Account minimums often make small volumes uneconomic | Scoped per program; ask before you assume |
| Cost at scale | Breaks down — you are running a warehouse | Efficient, once you clear the minimums | Efficient, minus the inbound freight and duplicate receiving |
Why general-merchandise warehouses get peptides wrong
A warehouse that ships phone cases and supplements is optimized for throughput, not for material whose integrity depends on how it was held. These are the four failure modes that do not show up on a packing slip — and the ones worth interrogating before you hand anyone your inventory.
Lyophilized is stable. Reconstituted is not.
Dry lyophilized peptide is comparatively forgiving — stable for extended periods at -20°C and for a shorter window at room temperature. Once reconstituted, that changes completely: solution-phase material is typically measured in days, not months, even refrigerated. Any fulfillment operation touching peptides has to understand which state it is holding, because the two have nothing in common in storage terms.
Lyophilized peptide is hygroscopic
The dry cake pulls moisture out of the air, and absorbed water drives hydrolysis and degradation. That makes humidity — not just temperature — a live variable in a warehouse. Sealed vials mitigate it; a compromised stopper or a repack operation in ambient humidity does not. This is the failure mode a general-merchandise 3PL has no reason to know about.
Freeze-thaw cycling is cumulative damage
Every freeze-thaw cycle costs a little integrity, and the damage does not reverse. A warehouse that stages inventory in and out of cold storage for picking — rather than pulling once, cleanly — is degrading product through pure process design. Ask any prospective 3PL how many times a given vial changes temperature zone between receipt and shipment.
Repacking can break RUO labeling
Research-use-only material carries labeling obligations that ride with the unit. A fulfillment partner that re-cartons, re-labels, or breaks a sealed configuration to build a bundle can quietly strip the compliance context your buyer needs. Kitting is fine — kitting done without preserving the original labeling is not.
Two temperature zones, monitored
Storage conditions are the part of a fulfillment quote that is easiest to assert and hardest to verify, which is why we would rather show you than tell you. Both zones are available for client-owned inventory, temperature is monitored, and you can ask to see the logs — before you commit stock, not after something goes wrong.
- −20°C Frozen
Long-term storage for lyophilized inventory
Where dry peptide holds its integrity over months rather than weeks. This is the default for stock that will sit before it sells.
- 2–8°C Refrigerated
Short-term and solution-phase material
For inventory turning quickly, and for anything reconstituted — where the stability window is measured in days and ambient is not an option.
Temperature control on its own is not the whole answer — a facility with perfect zones can still degrade product by cycling it in and out of them on every pick. Ask us the same question you should ask anyone: how many times does a vial change temperature zone between receipt and shipment?
What the fulfillment program covers
Everything between a finished vial and your customer’s door — run by the same operation that made the vial.
Cold-chain storage
Frozen storage at −20°C for long-term lyophilized inventory and refrigerated storage at 2–8°C, both available for client-owned stock. Temperature is monitored and the logs are yours to inspect — you should never have to take a storage claim on faith.
US warehousing
Your inventory is received, logged, and stored at our Costa Mesa, California facility. Domestic storage keeps customs out of the path between your stock and your customer, and keeps transit times short across the continental US.
Pick, pack & ship
Orders are picked against your inventory, packed to your spec, and handed to the carrier. Your team stops taping cartons and goes back to selling.
Lot-level tracking
Every unit stays tied to its lot record from receipt through outbound shipment — the same discipline we run on our own production. If a unit in a customer's hands ever needs tracing back to a batch, the record exists.
Kitting & bundles
Multi-compound kits, starter bundles, and configured packs assembled ahead of demand, so a multi-SKU order ships as one clean unit instead of four loose pieces.
Order-platform integration
We run ShipStation, which connects natively to the major storefront and marketplace platforms. Orders reach the floor without anyone rekeying them, and tracking flows back to your customer automatically.
Manufacturing in the same building
We are not a warehouse renting you shelf space. Production, labeling, and fulfillment run under one roof, so a restock is an internal transfer instead of a purchase order and a freight lane.
How fulfillment works
From first call to orders leaving the dock under your brand.
- 01
Scope the program
SKUs, volume, storage footprint, and how orders reach you today. Your account manager scopes it on the first call — no RFP process.
- 02
Receive & log inventory
Product arrives — produced here, or shipped in from you — and is counted, logged against its lot, and racked. You get a receipt record showing exactly what landed.
- 03
Connect your orders
Your store, marketplace, or order system connects through ShipStation so orders arrive automatically. A flat file or manual batch works too, if that is how you operate.
- 04
Pick, pack, QC
Each order is picked against the correct lot, packed to your spec — your labels, your inserts, your packaging — and checked before it is sealed.
- 05
Ship under your brand
Orders go out domestically with tracking returned to your system. Your customer sees your brand end to end; nothing in the box says Wholesale Peptide Supply unless you want it to.
Ten questions to ask any peptide 3PL before you sign
Including us. If a provider gets uncomfortable partway down this list, that is the answer. Take it to every quote you are comparing.
- 01
What temperature zones do you actually have, and can I see the logs?
“We have a fridge” is not a cold chain. Ask for dedicated zones and monitoring data you can inspect, not a verbal assurance.
- 02
How many times does a vial change temperature zone between receipt and shipment?
Every cycle is cumulative damage. A picking process that stages stock in and out of cold storage is degrading your product by design.
- 03
Is inventory tracked at lot level, or only by SKU?
SKU-level tracking cannot answer “which customers got lot 2481.” If you ever need a targeted recall, lot-level is the difference between a note and a catastrophe.
- 04
Do you rotate on expiry, or on whatever is closest to the door?
First-expired-first-out is the only rotation that makes sense for dated material. Ask whether it is enforced by the system or by whoever is picking.
- 05
Can you push inventory, lot, and tracking data back to my system?
If reconciling stock means a monthly spreadsheet, you do not have integration — you have a pen pal.
- 06
Which peptide brands do you currently serve, and can I talk to one?
If they cannot name a single peptide client, you are the pilot program. Charge them for it.
- 07
Who packs a glass vial, and what is the breakage rate?
General-merchandise pickers handle vials like they handle phone cases. Ask what the packout looks like and what the actual damage numbers are.
- 08
What happens to RUO labeling when you build a kit?
Bundling that strips or obscures research-use labeling creates a compliance problem that lands on you, not the 3PL.
- 09
What are the account minimums, and what triggers a surcharge?
Long-term storage fees and monthly minimums are where 3PL quotes quietly stop matching 3PL invoices.
- 10
If a lot is wrong, who fixes it — you or my manufacturer?
This is the question that exposes whether you have one accountable party or two vendors with a shared excuse.
Your orders reach our floor automatically
The difference between a fulfillment partner and a shipping vendor is whether anyone has to retype an order. We run ShipStation, which connects natively to the major storefront and marketplace platforms — so orders land on the floor the moment your customer places them, and tracking flows back without a status email from us.
Not running a storefront? Batched order files and manual submission both work. The integration should bend to how you already operate, not the other way around.
- Orders sync from your store — no rekeying, no copy-paste
- Tracking numbers return to your system automatically
- Inventory counts stay tied to lot records, not just SKUs
- Batched file or manual order entry supported
- One account manager across production and fulfillment
- Domestic outbound shipping from Costa Mesa, CA
How 3PL pricing actually works
Nobody quotes one number, which is why comparing providers is harder than it looks. Six lines make up almost every 3PL invoice. Ask for a worked example at your real order profile rather than a rate card — the rate card is where quotes look identical and invoices do not.
- Receiving
- Charged per pallet, carton, or unit when your inventory lands. Usually one-time per inbound shipment — and usually the fee people forget to model.
- Storage
- Recurring, billed per pallet, shelf, or bin per month. Temperature-controlled space costs materially more than ambient, which is why some quotes look suspiciously cheap.
- Pick fee
- Per unit pulled. Many providers price the first item in an order higher than each additional one, so order composition changes your effective rate.
- Pack / materials
- Cartons, dunnage, insulation, and labor. Peptides need more protection than the average parcel, and insulated packouts are not free.
- Postage
- The carrier's cost, sometimes with a markup and sometimes at the 3PL's negotiated rate. Worth asking which, because at volume it dominates everything above.
- Minimums & surcharges
- Monthly account minimums, long-term storage penalties on slow-moving stock, and peak-season adjustments. This is where a good-looking quote becomes an expensive invoice.
When you should not outsource fulfillment
If you are shipping a handful of orders a week, do it yourself. Account minimums make low volume uneconomic almost everywhere, and you would be paying for capacity you do not use. There is no version of this where a 3PL beats a person with a roll of tape at twenty orders a month.
Outsourcing starts earning its keep at the point where packing stops being a task and becomes a job — when mis-picks cost real money, when a single person leaving would stop shipments, or when the hours going into packouts are worth more spent on selling. If you are not there yet, we will tell you so on the first call rather than sell you a program you will resent in a quarter.
The other honest answer: if your volume is high but your product needs handling we cannot commit to, the right move is a specialist, not us. Ask the questions above and hold every provider — including this one — to the answers.
Who this is built for
Fulfillment is worth outsourcing at the point where shipping stops being a task and starts being a job.
Brands outgrowing their garage
You are shipping orders yourself, it is eating the week, and a mis-pick is now a real risk. Handing off pick-pack-ship buys back the time without hiring an ops team.
Distributors carrying multiple lines
You hold inventory across several brands and need one domestic location that can store it, kit it, and ship it — with lot records intact for anything that needs tracing.
Private-label lines launching now
You are already running a private-label program with us. Fulfillment is the piece that turns a production run into a business that ships without you in the loop.
One roof, one accountable party
The standard setup is a manufacturer in one place, a labeler in another, and a 3PL in a third — and when a shipment is wrong, three vendors point at each other. Production, labeling, and fulfillment all run out of our Costa Mesa facility, so there is exactly one party accountable for what is in the box.
It also collapses your restock cycle. When the product you sell is made in the building it ships from, replenishment is an internal transfer — not a purchase order, a freight lane, and a week of transit before you can fill orders again.

Peptide 3PL & fulfillment — FAQ
- Do you offer 3PL fulfillment for peptides?
- Yes. We provide third-party logistics for research peptide brands — receiving and storing your inventory at our US facility, picking and packing orders against lot records, and shipping domestically under your brand. Because we also manufacture and label in the same building, most clients run production and fulfillment as one program rather than coordinating two vendors. All compounds are handled strictly as chemical reagents for in-vitro laboratory research use.
- What is 3PL, and how is it different from drop-shipping?
- A third-party logistics provider stores your inventory and ships it on your behalf — the product is yours, sitting on our racks, going out under your brand. Drop-shipping means the supplier ships their own stock to your customer and you never own inventory. 3PL gives you control of your stock, your packaging, and your customer relationship without running a warehouse yourself. The trade-off is that you carry inventory risk; drop-shipping avoids that but gives up margin and brand control.
- Do you offer cold-chain storage for peptides?
- Yes. We hold client-owned inventory in two zones: frozen at −20°C for long-term lyophilized stock, and refrigerated at 2–8°C for material turning quickly or held in solution. Temperature is monitored in both, and you can ask to see the logs. Storage conditions are the easiest thing for a 3PL to assert and the hardest for a client to verify, so we would rather show you the data than ask you to trust the claim.
- Can I see your temperature logs before committing inventory?
- Yes, and you should ask — of us and of anyone else you are evaluating. A verbal assurance that a facility "has cold storage" tells you nothing about whether that storage held its setpoint last August. Ask for monitoring data before you ship stock, not after a lot comes back out of spec.
- How should lyophilized peptides be stored in a warehouse?
- Lyophilized (freeze-dried) peptide is comparatively stable — long-term at -20°C, and for a shorter window at room temperature depending on the compound. The bigger warehouse variables are humidity and handling. Lyophilized peptide is hygroscopic, so absorbed moisture drives hydrolysis and degradation, and every freeze-thaw cycle causes cumulative, irreversible damage. A well-designed operation minimizes the number of times a vial changes temperature zone between receipt and shipment.
- How is storing reconstituted peptide different?
- Completely different. Once a peptide is in solution its stability window collapses from months or years to days or weeks, even under refrigeration, and it typically requires 2–8°C or colder throughout. Most fulfillment programs for research peptides deal in sealed lyophilized vials for exactly this reason. If your product ships reconstituted, storage and transit requirements change substantially and you should scope that explicitly.
- What should I ask a peptide 3PL before signing?
- Ask what temperature zones they actually have and whether you can see the monitoring logs; how many times a vial changes temperature zone between receipt and shipment; whether inventory is tracked at lot level or only by SKU; whether rotation is enforced on expiry; whether they can push lot and tracking data back to your system; which peptide brands they currently serve; what the account minimums and long-term storage surcharges are; and — critically — who is accountable if a lot is wrong, them or your manufacturer.
- Can you integrate with my online store or order system?
- Yes. We run ShipStation, which connects natively to the major storefront and marketplace platforms, so orders reach our floor without anyone rekeying them and tracking numbers flow back to your customer automatically. If you would rather send batched orders as a file, that works too. Your account manager confirms the exact connection during setup.
- Does my inventory stay tied to its lot number?
- Yes. Every unit stays associated with its lot record from the moment it is received through the moment it ships — the same lot discipline we apply to our own production runs. SKU-level tracking cannot tell you which customers received which batch; lot-level tracking can, which is what makes a targeted response possible instead of a blanket one.
- Can you ship in my packaging, with my branding?
- Yes. Orders are packed to your spec — your labels, your inserts, your cartons. Nothing in the box identifies Wholesale Peptide Supply unless you ask for it. Because labeling is done in-house, branded product and branded fulfillment come from the same operation rather than two vendors trying to match each other.
- How does 3PL pricing usually work?
- Most providers bill across six lines: receiving when inventory lands, recurring storage by pallet or bin, a per-unit pick fee, packing materials and labor, postage, and then minimums or surcharges. The last category is where quotes and invoices tend to diverge — monthly account minimums and long-term storage penalties on slow-moving stock are easy to miss when comparing providers. Ask for a worked example at your actual order profile, not a rate card.
- Do I have to manufacture with you to use fulfillment?
- No. Fulfillment and manufacturing are separate programs and either works on its own. That said, most of the value appears when they are combined: a restock becomes an internal transfer instead of an inbound freight shipment and a second receiving step, the lot record is never re-established from paperwork, and there is one account manager accountable for both.
- When should I not outsource fulfillment?
- If you are shipping a handful of orders a week, doing it yourself is almost certainly cheaper — 3PL account minimums make low volumes uneconomic, and you would be paying for capacity you do not use. Outsourcing earns its keep when order volume makes packing a job rather than a task, when mis-picks start costing real money, or when your own time is worth more than the labor you are replacing.
- Where is the facility located?
- Costa Mesa, California. All storage and outbound shipping happen domestically, which keeps transit times short across the US and keeps customs out of the path between your inventory and your customer.
- Is fulfilled product intended for human use?
- No. All compounds we produce, store, and ship are supplied strictly as chemical reagents for in-vitro laboratory research and are not for human or veterinary use. Wholesale Peptide Supply is a B2B chemical reagent supplier — not a pharmacy or compounding facility as defined under 503A or 503B of the Federal Food, Drug, and Cosmetic Act. Clients are responsible for compliance with applicable law in their jurisdiction.
