There's no fixed maximum number of cycles
They cover peptide basics, the preclinical evidence for BPC-157 and TB-500, mechanisms like angiogenesis and tissue repair, the lack of robust human trials, sourcing risks, regulatory bans, and the gap between anecdotal reports and scientific certainty
Arteries can become lined with dangerous plaque and cause blood clots and other issues

Beyond the landmark 2007 study, the broader body of evidence supporting GHK-Cu for hair includes: Follicle enlargement studies: Multiple in vitro studies confirm GHK-Cu increases the size of hair follicles, reversing miniaturization the key driver of visible thinning in androgenetic alopecia Anagen phase extension: Research confirms GHK-Cu extends the active growth phase of follicles, producing longer, thicker hairs per growth cycle Minoxidil comparison: Some studies suggest GHK-Cu performs comparably to 5% Minoxidil for hair growth stimulation through a more targeted, follicle-specific mechanism with a significantly better side effect profile Wound healing evidence: GHK-Cu's extensive wound healing evidence (accelerating tissue repair by 3040%) is directly relevant to scalp health the same repair mechanisms that heal damaged skin also support follicle recovery from inflammation and miniaturization damage Anti-inflammatory scalp research: GHK-Cu's consistent anti-inflammatory effects in skin tissue translate directly to scalp applications reducing the follicle-damaging inflammation that accelerates hair loss GHK-Cu vs Minoxidil: The Honest Comparison GHK-Cu and Minoxidil work through complementary mechanisms Minoxidil primarily through vasodilation, GHK-Cu primarily through direct follicle cell stimulation and anti-inflammatory action
