02Verify your vial
Every vial label carries a QR code. Point your phone camera at it.
The code opens that lot's certificate with every assay value. No phone? Type the lot from your packing slip on Verify a lot.
Each signed certificate links to the lab's own verification page, so the report can be confirmed independently of us.

Sequence
Side-chain composition
Every heavy atom is placed from the sequence with ideal bond lengths and angles, so the connectivity is exact. The pose is idealised (an extended chain) and is not a measured conformation. Identity for each lot is confirmed on its certificate.
Structure viewer04In the lab
Ipamorelin is a five-residue peptide that releases growth hormone through the GHRP receptor, also described as the ghrelin receptor. In laboratory models its GH release was selective, without the ACTH and cortisol rise seen with GHRP-6 and GHRP-2.
Compound
IpamorelinSynthetic pentapeptide, Aib-His-D-2-Nal-D-Phe-Lys-NH2Pituitary cells
Endpoint studied
Released GH from pituitary cells as potently as GHRP-6; ACTH and cortisol did not rise in laboratory models.
Raun 1998 · PMID 9849822Gastric smooth muscle
Endpoint studied
Restored acetylcholine- and nerve-driven contraction of gastric muscle in an ileus model; emptying sped up.
Greenwood-Van Meerveld 2012 · PMID 27186127Pancreatic tissue
Endpoint studied
More insulin release from normal and diabetic pancreatic tissue; calcium channel or adrenergic blocks cut it.

About Ipamorelin, its certificate and your order.
Email [email protected], Monday to Friday. A person replies within one business day.
The current released lot, SA-IPA-2610. Scan the QR code on the vial label to open its certificate. The lot number is also on your packing slip, and the full certificate is here.
Every certificate is issued by an independent laboratory. Each lot has its own public record page with every assay value, and a link to verify the report on the lab's own site once the signed PDF is posted.
Vials are filled slightly over the labelled mass so that every vial meets it. Net content is measured on each lot and published as a number, not a pass.
Email [email protected] within 7 days with your order number and a photo and we will replace it.
Orders by 2 PM ET on a weekday ship the same day, with tracking emailed when the label prints.
