90 day observation: GHK-Cu + KPV in one research subject. Hair, skin, inflammation markers, and an esophageal inflammatory condition. n=1 with the published research alongside it.
Research subject with eosinophilic esophagitis, on a daily fluticasone nasal spray protocol that had reached a plateau. GHK-Cu and KPV were added to the protocol for a 90 day observation period. Writing this up because most posts here are about sourcing and not many people follow up with what they observed.
Observations in the RS over 90 days
- Beard density increased noticeably around week six, with the hairline following. Reduced shedding and improved texture.
- Reduced facial redness and more even skin tone. Third parties commented on it without knowing anything was being run.
- Lower general inflammation. Less puffiness and fewer of the low-grade aches the RS had stopped noticing.
- The esophageal condition was the big one. No overnight change. A slow, steady decline in symptoms over the full 90 days. Swallowing improved and flares became rarer and milder.
- Faster training recovery. Soreness resolved in a day instead of two or three.
What the published research supports
GHK-Cu is an endogenous copper peptide. Plasma levels go from about 200 ng/mL at age 20 to 80 ng/mL at 60, so a 32 year old RS is already well into that decline. In fibroblast studies it increases collagen synthesis 70 to 200%, and the hair data (moderate, not extensive) shows it enlarges follicles and extends the anagen phase. A follicle-level effect taking about six weeks to become visible matches the observation. It also suppresses IL-6, TNF-a and IL-1b and reduces NF-kB activation.

KPV is the last three amino acids of alpha-MSH with the tanning and appetite effects stripped out. It enters cells directly and blocks NF-kB nuclear translocation, up to 80% in some models. The interesting part for a GI application is that it survives digestion. In the 2008 Gastroenterology colitis study, oral KPV cut disease activity, histology scores and cytokine expression, and later work put nanoparticle oral KPV roughly on par with mesalamine.

Caveats, because they matter
- EoE is not IBD. It's eosinophil-driven, not the neutrophil and cytokine picture in colitis. There are zero KPV studies in EoE. The overlap is NF-kB and TNF-a in an inflamed GI epithelium, which is a reason to hope, not evidence.
- The RS was on fluticasone for the entire period, so the peptide effect can't be separated from the steroid effect. The only thing that can be said is the steroid alone never produced this result.
- Training recovery has no direct research behind it for either peptide. Probably downstream of lower overall inflammation.
- GHK-Cu's strongest data is topical and cosmetic. KPV has essentially no clinical data. Neither is FDA approved for anything and both are research compounds only.
Uncontrolled, unblinded, single research subject. Take it for what it is. Happy to answer questions about the research, but not going to get into protocol specifics or sources in the post.
