GHRP-2 and GHRP-6 — growth hormone secretagogues in research (guide)
GHRP-2 and GHRP-6 are the two most frequently mentioned peptides from the family of growth hormone-releasing peptides – short, synthetic molecules that in research models stimulate the pituitary gland to release growth hormone. Both come from the same generation of secretagogues discovered by Cyril Y. Bowers’ team, and both act through the same receptor, the GHS-R1a ghrelin receptor. The record varies: in […]
