sermorelin and ghk-cu together 101: How This Peptide Stimulates Natural Growth Hormone Sermorelin Protocol | from $129/mo

A common approach is to apply GHK-Cu in the morning and retinol or tretinoin at night

The rationale for combining them is mechanistic complementarity (different signaling pathways, all three implicated in tissue repair and dermal remodeling) and clinical anecdote in the peptide-therapy community not formal head-to-head, combination-vs-monotherapy, or concentration-response data on the blend itself

Replenishing physiological levels of GHK-Cu has been shown to offer powerful regenerative and reparative longevity actions including collagen and elastin synthesis, DNA repair, stem cell renewal processes, restoring an appropriate inflammatory response, neurological and cardiovascular protection, and the reset of epigenetic programming

This protocol should only be used under professional guidance

A popular combination approach uses 27 mg GHK-Cu + 10 mg TB-500 + 5 mg BPC-157, dosed at 0.9-1.8 mg of the blend daily for 6 weeks
