Compounds studied for growth-hormone-axis research.
Growth-hormone-axis research studies secretagogues and GHRH analogs that influence pulsatile growth-hormone release and downstream IGF-1 signaling. The compounds grouped here — selective ghrelin-receptor agonists, the CJC-1295/Ipamorelin blend, and stabilized GHRH analogs like Tesamorelin — are investigated in preclinical and clinical research for how they modulate the GH axis while limiting cortisol and prolactin elevation. These are research compounds, characterized by the pathway they act on, not therapeutic products.
For laboratory research use only. Compounds are catalogued by research interest, not as treatments or outcomes for human use. Last reviewed May 29, 2026.
Each compound below is drawn from our catalog and grouped here by the research interest that defines it. Every card links to its full research and sourcing page; dosing figures are summarized from published research literature, not advice.
GH secretagogue blend
The CJC-1295/Ipamorelin blend is the most-studied growth-hormone secretagogue combination.
selective GH secretagogue
Ipamorelin is a selective growth-hormone secretagogue studied on its own and in blends.
GHRH analog
Tesamorelin is a stabilized GHRH analog studied for growth-hormone-axis research.

Curated multi-compound protocols built only from compounds we cover, dosed with the published-research literature range, and rated by how mature the research base actually is.
CJC-1295 + Ipamorelin
The most-studied growth-hormone secretagogue combination. CJC-1295 is a GHRH analog that raises the baseline of GH release, while Ipamorelin is a selective ghrelin-receptor agonist that produces a clean GH pulse with minimal effect on cortisol or prolactin.
Tesamorelin + BPC-157
Tesamorelin is a stabilized GHRH analog studied for the growth-hormone axis at larger doses than the secretagogue blends. Paired with BPC-157, the protocol reflects research interest in running a GH-axis agent alongside a dedicated tissue-repair agent — a sustained hormonal-axis signal plus a frequent-dose local repair compound.
Ipamorelin + TB-500
Ipamorelin is a selective growth-hormone secretagogue that produces a clean GH pulse without the GHRH-analog component, making it the lighter-touch option for the GH arm of a recovery protocol. Paired with TB-500’s systemic cell-migration research, this stack reflects interest in a discrete pulsatile GH signal alongside a longer-acting systemic repair agent.
