Storage & reconstitution

Before opening

Lyophilised powder is stable at ambient temperature in transit. On arrival, store sealed vials in a cool, dry, dark place. For storage beyond three months, keep at −20 °C.

Reconstitution

Add bacteriostatic water slowly down the inner vial wall. Do not shake — swirl gently until fully dissolved.

After reconstitution

Refrigerate at 2–8 °C and protect from light. Use within 30 days. Discard if the solution becomes cloudy or discoloured.

For laboratory research use only. Not for human or veterinary consumption. Not a drug or dietary supplement.

Research record · preclinical

Three characterised lines of work

Ipamorelin operates by stimulating the pituitary gland to produce growth-related secretions in animal studies. Additionally it has been observed to reduce the production of somatostatin a secretion that can inhibit growth hormone release. Research also indicates that Ipamorelin may enhance the production of IGF-1 (Insulin-like Growth Factor 1) which is associated with processes involved in the growth and repair of muscular and skeletal tissues.

Secretagogue receptor route

The original characterisation describes a pentapeptide identified within a series of compounds lacking the central Ala-Trp dipeptide of GHRP-1. In primary rat pituitary cells it released growth hormone with potency and efficacy reported as similar to GHRP-6, at an EC50 of 1.3 nmol/l against 2.2 nmol/l. Profiling with GHRP and GHRH antagonists indicated that release proceeds through a GHRP-like receptor rather than the GHRH receptor, which is the basis on which the compound is separated from the GHRH analogues sold alongside it.

Eur J Endocrinol 1998

Potency across species

The same report describes dose-response work in two animal models: in pentobarbital-anaesthetised rats an ED50 of 80 nmol/kg with a maximum of 1545 ng growth hormone per ml, and in conscious swine an ED50 of 2.3 nmol/kg with a maximum of 65 ng/ml plasma. Both are given against GHRP-6 measured in parallel, and both are reported as comparable to it.

Eur J Endocrinol 1998

Later receptor-level work

A 2024 study examined two growth hormone secretagogue receptor 1a agonists in ferrets given cisplatin, reporting that both anamorelin and ipamorelin inhibited the weight loss and reduced feeding seen in acute and delayed phases. The anti-emetic effect described in that work is attributed to anamorelin alone and to a central mechanism, with the two compounds also compared on electrically stimulated contractions of isolated ileum.

Appetite and body weight	Cisplatin-induced weight loss and feeding in ferrets

The characterisation this record rests on is preclinical and dates to 1998, in rat pituitary cells and in two animal species. A 2020 review of growth hormone secretagogues in the management of body composition states that clinical efficacy data for this class largely remain lacking, and a 2026 review of peptides used in sports medicine catalogues the compound among those marketed to patients without regulatory approval. The compound holds no FDA approval.

Common questions

Ordering, handling and compliance. Anything not covered here, write to support@pureforgelabs.com.

What does research use only actually mean?

Every compound we sell is supplied for laboratory research and development only. It is not a drug, not a supplement, and not intended to diagnose, treat, cure or prevent any condition in humans or animals. Buying from this site means you are acquiring it for in vitro or other controlled research work.

Who is allowed to order?

Purchasers must be 21 or older and are responsible for compliance with the law where they take delivery. We ship to research institutions, laboratories and qualified individual researchers. We do not ship to jurisdictions where these compounds are restricted.

How do I read the certificate of analysis?

Check three things in order. First, the lot code on the certificate matches the code printed on your vial. Second, the HPLC chromatogram shows a single dominant peak with the stated purity figure. Third, the LC-MS mass matches the expected molecular weight, here 1419.56 g/mol. Anything that does not line up, send us the lot code.

How do I reconstitute and store it?

Add bacteriostatic water slowly down the inner wall of the vial and swirl — never shake. Once in solution, refrigerate at 2–8 °C, protect from light and use within 30 days. Unopened vials keep at ambient temperature short term, or at −20 °C beyond three months.

When does it ship and how?

Orders placed before 2 PM Pacific dispatch the same working day. Domestic delivery is two days, with tracking sent on dispatch. Shipping is free on orders over $200. International orders go out with a commercial invoice; transit is typically five to nine days.

What payment methods do you take?

Institutional purchase orders and bank transfer are available on wholesale accounts — apply through the wholesale programme and we will set up terms.

What if a vial arrives damaged?

Photograph the vial and outer packaging and email us within 48 hours of delivery. We replace damaged or compromised vials at our cost. Unopened vials can be returned within 30 days; opened vials cannot be resold and are not returnable.

Do you handle bulk and wholesale orders?

Yes. Volume pricing on this page runs to five vials; beyond that, a wholesale account gives tiered pricing, reserved lots and consolidated shipping. Reserved lots matter for multi-month studies where you need the same batch throughout.
