glutathione firefighters Why California won't give easier access to key drug Xenobiotics and Tactical Health: Protecting

PLU Laboratories makes cosmetic products, not drugs, so we do not make hair-growth claims

The evidence does not support that claim

Why these two get studied together The short answer is that the preclinical literature on each peptide individually points at overlapping but distinct elements of the wound-repair toolkit: BPC-157 has been associated with angiogenesis and growth-factor signaling, while thymosin beta-4 fragments have been associated with cell migration

Most researchers recommend cycling protocols (8-12 weeks on, 4 weeks off) rather than continuous indefinite use until more long-term data becomes available

What Would Change This View A negative RCT in living skin If a properly powered randomized trial of at-home microinfusion with GHK-Cu versus matched topical control failed to show histologic or photographic differences at 12 weeks, that result would shift the position of this article from "biologically plausible recommendation" to "interesting hypothesis pending data." A safety signal in long-term at-home users If the consumer at-home microinfusion category began producing case reports of infection, scarring, or persistent dermal damage at rates higher than baseline microneedling, the depth recommendation would tighten or the route would be deprecated
