The full GH / IGF-1 axis catalog — priced per vial, shipped tracked from US fulfillment in 3–5 business days. Free shipping over $200. Every vial includes a lot-matched Certificate of Analysis confirming ≥98% HPLC purity. Organized by axis node (hypothalamus → pituitary → liver) so you can pair GHRH + GHRP compounds for additive receptor engagement.

Axis Cascade

Hypothalamus

GHRH release → pituitary trigger

Ghrelin Receptor

GHSR-1a binding → GH pulse amplifier

Pituitary Output

GH released → plasma elevation

Hepatic IGF-1

GH-driven IGF-1 synthesis + bioavailability

01

Axis Node 1

Hypothalamus

GHRH release → pituitary trigger

02

Axis Node 2

Ghrelin Receptor

GHSR-1a binding → GH pulse amplifier

Research Note · Stacking

GHRH analogs and GHRP secretagogues are commonly co-administered in research protocols — the two receptor classes (GHRH-R and ghrelin-R / GHSR-1a) produce additive GH release when engaged simultaneously. The most-researched pairing is CJC-1295 + Ipamorelin, with data going back to the original Teichman et al. (2006) pulsatility study.
