Is Ipamorelin third-party tested?

Yes. Every lot of Ipamorelin is tested by an independent third-party laboratory using HPLC/MS, and a per-lot Certificate of Analysis documenting identity and purity is available as a paid add-on.

Is Ipamorelin for human use?

No. Ipamorelin is sold strictly as a chemical reagent for in-vitro laboratory research and is not for human or veterinary use. Wholesale Peptide Supply is not a pharmacy or compounding facility.

How do I get wholesale pricing for Ipamorelin?

Request a quote through our contact form or open a wholesale account. An account manager replies with volume pricing and lead times, typically within 10 minutes during business hours.

Can I order Ipamorelin in bulk?

Yes. Ipamorelin is available for bulk and wholesale orders, quoted by dose and volume, with the lower price earned per compound at 100 kits (1,000 vials). Submit the doses and quantities you need for a bulk quote; all material is sourced in the USA and third-party HPLC/MS tested.

How does ipamorelin differ from CJC-1295 or sermorelin?

They act through different receptors. Sermorelin and CJC-1295 are GHRH analogs that engage the GHRH receptor, while ipamorelin is a pentapeptide secretagogue acting through the secretagogue receptor. Because the mechanisms are distinct, they are frequently studied in parallel rather than as substitutes, and blends pairing the two classes are stocked as separate catalog lines.

Why was ipamorelin developed as a selective compound?

Earlier GHRP-class secretagogues engaged additional endocrine pathways alongside the intended target, which complicated attribution in laboratory models. Ipamorelin was developed in the 1990s and selected for minimal off-target pathway interference, making it useful where a clean, narrowly attributable readout matters.

Overview

Ipamorelin is a synthetic pentapeptide and selective secretagogue-type agonist with minimal off-target pathway interference, used to study endocrine signaling and somatotroph axis modulation.

History

Developed in the 1990s as a more selective alternative to earlier GHRP-class compounds.

Structure and mechanism

Ipamorelin is a synthetic pentapeptide developed in the 1990s as a deliberately selective alternative to the earlier GHRP-class secretagogues. The design goal was narrowness: earlier compounds in the class engaged additional endocrine pathways alongside their intended target, which made clean attribution difficult in laboratory work. Ipamorelin was selected for minimal off-target pathway interference, and that selectivity is its main research value.

In preclinical models it is used to probe somatotroph axis signaling where a confounded readout would be a problem, and as the selective comparator against less specific GHRP-class compounds. At 711.9 g/mol (C₃₈H₄₉N₉O₅) it is one of the smallest compounds in the growth hormone category — an order of magnitude lighter than the GHRH analogs it is often studied beside, and mechanistically distinct from them, since it acts through the secretagogue receptor rather than the GHRH receptor.

Reconstitution and handling (research use)

Wholesale ipamorelin ships lyophilized and is among the more forgiving compounds in the catalog to handle. At pentapeptide scale it dissolves rapidly in bacteriostatic or sterile water and is not meaningfully prone to the shear and foaming problems that affect multi-kilodalton peptides, though gentle handling remains good practice.

Lyophilized material is generally stored at -20°C protected from light; reconstituted solution is refrigerated at 2–8°C and used within the working window the protocol defines. These notes describe general laboratory handling of a chemical reagent only — not human or veterinary use.

Wholesale sourcing notes

Ipamorelin is stocked wholesale in 5 mg and 10 mg presentations and is one of the higher-volume lines in the growth hormone category. Every lot is US-sourced and independently verified by third-party HPLC/MS for identity, purity, and quantitation, with a per-lot COA available as a paid add-on.

It is most commonly ordered together with the GHRH-class compounds — CJC-1295, sermorelin, and tesamorelin — since the two mechanisms are studied in parallel; CJC/IPA and tesamorelin/ipamorelin blends are stocked as separate lines. Volume pricing runs across the 100, 250, 500, and 1,000-vial bands under a 100-vial mix-and-match minimum.
