Muscle-building & cutting peptides

Growth-hormone axis research peptides

The peptides in this category are used to study the growth-hormone axis — the chain of signals running from the hypothalamus to the pituitary gland and on to downstream factors such as IGF-1. Typical lines of enquiry include GHRH-receptor activity, ghrelin-receptor activity and the pulsatile pattern of hormone release.

In this category

Tesamorelin is a stabilised analogue of growth-hormone-releasing hormone (GHRH). CJC 1295 + DAC is a GHRH analogue carrying a drug-affinity complex, which lengthens its half-life in research models. CJC 1295 + Ipamorelin combines a GHRH analogue with a selective ghrelin-receptor agonist and is often used to look at how the two pathways interact.

How they differ

The key differences are the receptor targeted and the duration of action. Shorter-acting compounds suit work on pulsatile release; longer-acting analogues suit work on sustained signalling. Check the literature for your model before choosing.

Testing and handling

Certificates of analysis are published on the lab testing page. Keep freeze-dried vials refrigerated, reconstitute with bacteriostatic water, and see the Cutting & Lean-Mass Bundle for a combined set.
