Avoid, Moderate Risk

Two GHRHs in the same regimen

Two GHRHs (e.g. CJC-1295 + Sermorelin, CJC-1295 + Tesamorelin)

Why this combination is flagged

Same receptor: competition at pituitary GHRH receptor; no additive benefit, reduced efficiency

Reported risk level

Moderate, per peptide research and practitioner literature catalogued on PeptideHelper.org.

Peptides involved

Safer alternatives reported in literature

Pair a single GHRH (CJC-1295, Sermorelin, OR Tesamorelin) with a GHRP / ghrelin receptor agonist (Ipamorelin, GHRP-2/6, Hexarelin); the two classes act on complementary pathways and yield 2-3× GH release vs. either alone. The Gold Standard GH stack (CJC-1295 + Ipamorelin) is the most-cited example.
