Ipamorelin, the First Selective Growth Hormone Secretagogue
European Journal of Endocrinology
Foundational paper establishing ipamorelin as a selective GHS-R1a agonist. Unlike GHRP-2 and GHRP-6, ipamorelin does not stimulate ACTH or cortisol, making it uniquely selective.
Pharmacokinetic-Pharmacodynamic Modeling of Ipamorelin in Human Volunteers
Pharmaceutical Research
Dose-escalation trial demonstrated ipamorelin produces a GH release episode peaking at 0.67 hours with terminal half-life of 2 hours across five dose levels in healthy male volunteers.
Ipamorelin Induces Longitudinal Bone Growth in Rats
Growth Hormone & IGF Research
Ipamorelin dose-dependently increased longitudinal bone growth rate from 42 to 52 µm/day with pronounced dose-dependent effects on body weight gain in adult female rats.
Ipamorelin, a New Growth-Hormone-Releasing Peptide, Induces Growth Hormone Release via Hypothalamic GHS-R1a in Conscious Rats
Growth Hormone & IGF Research
Ipamorelin demonstrated potent, dose-dependent GH release without affecting ACTH, cortisol, prolactin, FSH, LH, or TSH — establishing it as the most selective growth hormone secretagogue known.
The GH Secretagogue Ipamorelin Counteracts Glucocorticoid-Induced Decrease in Bone Formation of Adult Rats
Growth Hormone & IGF Research
Ipamorelin prevented dexamethasone-induced bone loss in adult rats, maintaining bone formation markers and trabecular bone mineral density through sustained GH/IGF-I axis stimulation.
Acceleration of Postoperative Bowel Recovery by Ipamorelin: A Novel Growth Hormone Secretagogue
Neurogastroenterology & Motility
Phase II trial in patients after abdominal surgery demonstrated ipamorelin significantly accelerated time to first bowel movement and hospital discharge, acting through ghrelin receptor-mediated prokinetic effects.
IPAMORELIN FAQ
Where is ipamorelin for sale?
Blank Peptides carries ipamorelin in 10mg vials, singly or with volume pricing (buy three, save 10%; buy nine, save 25%), produced in our cGMP labs in the USA. Every vial ships with a lot-matched COA you can open before ordering. We sell to researchers directly, with no prescription step, and orders have a processing time within 1 business day.
What is ipamorelin?
Ipamorelin is a pentapeptide and a selective agonist at the GHS-R1a receptor, the same receptor ghrelin binds. Its selectivity is the reason it appears so often in the literature: in animal studies it triggers growth hormone release without the cortisol and prolactin effects seen with earlier secretagogues, which makes it a cleaner tool for isolating GH pathway questions.
What purity is your ipamorelin?
Greater than 99%. We run HPLC and mass spectrometry on every lot in house, then send an independent sample to Freedom Diagnostics or Horizon Analytical for confirmation. Bacterial endotoxin testing is part of batch release. The certificate we publish is tied to the lot number on your vial rather than to a representative batch.
How do I reconstitute ipamorelin 10mg?
1mL of bacteriostatic water into the 10mg vial gives 10mg/mL, our standard ratio. Let the solvent run down the side of the glass, then swirl slowly. Ipamorelin is a short peptide and normally goes into solution within seconds.
How should ipamorelin be stored?
Sealed and lyophilized at -20C, kept dark and dry. Freeze-dried powder tolerates ambient shipping temperatures. After reconstitution, store at 2 to 8C and plan on using the solution within a few weeks. If a protocol runs longer, aliquot into sterile vials rather than freezing and thawing the same one repeatedly.
Ipamorelin vs CJC-1295: do researchers use them together?
Often, because they hit different receptors. Ipamorelin is a ghrelin receptor agonist while CJC-1295 no DAC is a GHRH analogue, so combination studies look at what happens when both pathways are engaged at once. Our CJC-1295 and ipamorelin blend puts both in a single vial for that purpose.
How fast does ipamorelin ship?
Processing time is within 1 business day, shipping domestically from inside the USA in plain outer packaging. Tracking is emailed at label creation. Multi-vial packs ship together in one box. If a vial arrives cracked or the cake has shifted noticeably, photos to support get it replaced.
Can ipamorelin be bought without a prescription?
Yes, as a research chemical. Ipamorelin has never been approved by the FDA for any indication, is not a drug or supplement, and is not for human or veterinary use. It is also WADA prohibited. Placing an order confirms the material stays in a laboratory setting under a qualified researcher.
