GHRH analogues are synthetic linear peptides modelled on the 44-residue native GHRH sequence or on its 29-residue N-terminal segment. The category also carries the shorter C-terminally amidated pentapeptides and hexapeptides that the peptide literature conventionally files alongside them. Structural variations across the family include D-amino-acid substitutions at individual positions, N-terminal acylation, C-terminal amidation and, in some members, a lysine side-chain linker. Each compound is supplied as a lyophilized powder in a sealed vial; lyophilized peptides of this length are hygroscopic, so vials are supplied sealed and are best stored dry and cold.
Listed here: Ipamorelin, CJC-1295 no DAC, Tesamorelin, Sermorelin, AOD-9604 (5mg, 10mg). Each product page lists the CAS number, molecular formula, molecular weight and, for peptides, the amino-acid sequence. Reported HPLC purity is shown per product; the HPLC and mass-spectrometry identity report is sent by email on request, before you order if you want to see it first.

Frequently asked questions
Which compounds are listed in the GHRH analogue category?
This category currently lists 5 compounds: Ipamorelin, CJC-1295 no DAC, Tesamorelin, Sermorelin and AOD-9604, each supplied as lyophilized powder in a sealed vial at the nominal quantity printed on the label. Each product page states the CAS number, molecular formula, average molecular weight and sequence, the reported HPLC purity for the listing and, where a verified record exists, the typical salt form, structural class and residue count.
What is a GHRH analogue, chemically?
A synthetic linear peptide modelled on the 44-residue native GHRH sequence or on its 29-residue N-terminal segment, usually as a C-terminal amide. Variations across the family include D-amino-acid substitutions at individual positions, N-terminal acylation such as a trans-3-hexenoyl group, C-terminal amidation and, in some members, a lysine side-chain linker. The category also files the shorter C-terminally amidated peptides that the peptide literature conventionally lists alongside them, some built from non-coded residues such as Aib and 3-(2-naphthyl)-D-alanine, together with any other short peptide the catalogue assigns to the group. Peptide sequence notation explains how the termini and non-coded residues are written on a listing.
How do I buy a GHRH peptide online from Pepta Labs?
From its product page: choose the vial or pack and order from a free account with a confirmed email (buyers must be 21 or older); each listing ships free to United States addresses as dry lyophilized powder at ambient temperature. The full ordering terms are in the research peptide catalog FAQ.
