PepEvolutionCJC-1295 + Ipamorelin
CJC/Ipa blend
The most widely used GH secretagogue stack — clean pulse, good availability, component-derived evidence.
Verdict — B · Viable
The category workhorse for GH-axis support — cleaner side-effect profile than GHRP-6, good sourcing availability, well-understood mechanism. The blend lacks its own RCT but component data is solid. Buy it with a fresh, batch-specific COA from a vetted vendor.
Overview
The CJC-1295 (no DAC) + Ipamorelin combination is the dominant GH secretagogue stack in the gray-market peptide space, pairing a GHRH analogue with a selective ghrelin-mimetic GHRP to co-amplify the natural GH pulse. Neither compound is FDA-approved, but both have reasonable individual evidence bases and the pairing is extensively documented. Ipamorelin's selective profile minimizes the cortisol and prolactin co-stimulation seen with older GHRPs. Compounding pharmacies commonly carry this blend and COA coverage is moderate-to-good.
