View brandDetailed compound information
Ipamorelin is a pentapeptide ghrelin-receptor (GHS-R1a) agonist that triggers pulsatile GH release from pituitary somatotrophs. Its defining property is receptor selectivity — at typical research doses it produces minimal cortisol, prolactin, or ACTH elevation, distinguishing it from earlier GHRPs like GHRP-6 or GHRP-2. This makes it the cleanest GHRP for extended-cycle research protocols.

Already setting myself a reminder to reorder before my current vial runs out so I do not miss a beat. Shipping was fast, packaging was clean, quality is consistent with the lab report. No complaints from me at all.
Research peptides are chemical reagents for laboratory analysis. Regulations vary by jurisdiction — it is the buyer's responsibility to ensure compliance with local laws. See our Terms & Conditions page for the full regulatory framework across the EU, UK, US, Switzerland, Thailand, and other major markets.
Lyophilized (unreconstituted) peptides should be stored at -20°C for long-term storage or 2-8°C (refrigerated) for short-term use. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles — aliquot into smaller portions if needed.
For laboratory research use only. Not for human consumption, diagnosis, treatment, prevention, or in-vivo administration. By purchasing you confirm you are a qualified researcher or institution.
Reconstitute the 5mg vial with 2mL bacteriostatic water → 2.5 mg/mL. On a U-100 insulin syringe, 10 IU = 0.1 mL = 250 mcg per pulse.
Je reviens parce que rien ne s'est jamais mal passé. Suivi tout au long de l'expédition, emballage solide, qualité constante d'un lot à l'autre. Le site est clair et le support a répondu à ma question en moins d'une journée.
Gently inject bacteriostatic water (bacteriostatic water) along the inside wall of the vial — do not spray directly onto the powder. Let it dissolve naturally or gently swirl. Never shake vigorously. Standard reconstitution: add the desired volume of bacteriostatic water based on your concentration needs. For example, 5mg peptide + 2.5ml bacteriostatic water = 2mg/ml concentration.
Yes. Every batch undergoes independent third-party HPLC (High-Performance Liquid Chromatography) and mass spectrometry analysis. We provide a Certificate of Analysis (COA) for each product, verifying identity, purity (≥99%), and the absence of contaminants. COA documents are available for download on each product page.
Yes. We offer temperature-controlled shipping to most EU and Asian countries. Standard EU delivery is 24-48 hours. International orders are shipped in discreet, professional packaging with cold-chain protection where required. Customs documentation and regulatory paperwork are provided as needed.
