Peptides from growth-hormone-release research: GHRH analogues such as tesamorelin, and blends pairing a GHRH analogue with a GHRP like ipamorelin.
This category holds peptides from research into growth hormone release. Two classes recur: GHRH analogues, acting on the GHRH receptor in the pituitary, and growth hormone secretagogues, working through the ghrelin receptor. Both stimulate the body's own release rather than administering growth hormone itself.
That distinction is exactly what makes the area scientifically interesting. Administering growth hormone directly bypasses the natural feedback loop; stimulating endogenous release leaves it intact and preserves the pulsatile pattern. Research in this area is often about that difference.
Apart from tesamorelin — registered in the United States for one indication — none of these peptides holds a marketing authorisation.
The same applies to every peptide in this category: the documentation decides whether the material is usable.
