What is Ipamorelin and what is Thymosin Alpha-1?
Ipamorelin is classified as Synthetic pentapeptide secretagogue; Thymosin Alpha-1 as Synthetic 28-amino-acid thymic peptide. Both profiles below cover scientific identity only — what the molecule is and which laboratory models it appears in. Verve supplies both strictly as in-vitro reference materials, and neither profile describes human or veterinary use.
Ipamorelin
Synthetic pentapeptide secretagogue
Ipamorelin is a synthetic pentapeptide and a selective growth-hormone secretagogue, meaning it is characterized in the literature as an agonist at the growth-hormone secretagogue receptor (GHS-R1a), the same receptor targeted by the endogenous ligand ghrelin. Its selectivity profile is the reason it is so frequently chosen as a reference agonist in receptor-signaling work.

Synthetic 28-amino-acid thymic peptide
Thymosin Alpha-1 is a 28-amino-acid peptide corresponding to a sequence originally characterized in thymic tissue extracts, where it was identified as part of the prothymosin alpha precursor. Verve supplies it as a high-purity synthetic research compound for the laboratory study of peptide-mediated immunological signaling.
