What the skin reports say

Each row is a published confession. A report can be about more than one thing. These are stories, not rates.

Face looked about a decade younger; hair did not regrowGHK-Cu#75

Safety notes users raise

#82 is a warning: melanotan darkened existing moles and new ones appeared. Changing or new moles need a dermatologist. Home-mixed products, as in #91, are not quality-controlled. In Canada, Health Canada lists GHK-Cu and melanotan among unauthorized injectable peptides — see are peptides legal in Canada?.

31M - Retatrutide/MOTS-C/GHK-CU That’s it that’s the stack. Don’t over complicate it

MOTS-cRetatrutideGHK-Cu

I stopped vaping after years, thanks to reta. I’ve always struggled with food and food noise until reta came along. My weekend interval training improved because of MOTS-C, and GHK-Cu has my skin looking like I’m 20 again. And I’m not even 30 yet.

MOTS-cRetatrutideGHK-Cu

Seeing the latest confession prompted me to tell me Ghk cu story. Ghk cu/ahk cu topical by precise formulations stopped my hair loss drastically within a month where injectable 3mg daily didn't do anything for me. And no it's not an ad just my experience

#127
GHK-Cu

Im a peptide fanatic. Two years deep in peptides. Honest notes, just what each actually does in my body. CJC-1295 with Ipamorelin is my sleep fix. Used to wake five times a night, now I'm out cold till morning. GHK-Cu I'll never drop. Tore my forearm open on a bike chain last summer and it closed clean enough to surprise the urgent care guy. SS-31 is the weird one. Closest thing to the lights coming on, and my recovery between hard sessions got noticeably shorter. Semax flips my focus to overdrive. Great for deadlines, useless past early afternoon or I can't sleep. Tirzepatide slowed my gut so much I had to move my night supplements earlier, they just sit there otherwise. BPC-157 is the quiet one for joints and gut. I only notice it when I run out. Thing nobody warns you about with almost all of them: water weight. I'll wake up 5 pounds up and it's pure sodium, not fat. Took me way too long to stop letting the scale wreck my morning.

GHK-Cu did nothing for my hair in 6 months. what it DID do is fade two surgery scars to almost nothing and make people think I'm younger than I am. bought it for the wrong reason, kept it for the right one.

GHK-Cu

GHK-Cu didn't regrow my hair. it un-aged my face by a decade instead. I now look younger than my little brother and he will not let it go. worst best side effect of my life.

#075
GHK-Cu

I took bpc-157, tb-500, and ghk-cu post foot surgery and wish I started them the day after surgery not 5 weeks after. My recovery would have been much faster [edited: promotional content removed]

TB-500BPC-157GHK-Cu

injured my leg last year, its been horrible ever since.. learned about peptides but was too scared to test on myself so i injected my 12 year old cat with bpc157, 4 weeks later coco is jumping all around, we're now both on bpc

Community Q&A

What peptides are used for skin?
In this archive, mostly GHK-Cu (65 published confessions tagged GHK-Cu), plus a few KPV and melanotan reports. Only a handful of those describe a skin change.
Does GHK-Cu help skin, according to users?
Two reports describe a visible change: #75 says their face looked about a decade younger and #86 says two surgery scars faded. Both say it did nothing for their hair. Two stories are not evidence.
Are there skin side effects?
#82 says melanotan darkened every existing mole and new ones appeared. That is a reason to see a dermatologist, not a cosmetic quirk.
Does this page recommend products or doses?
No. Peptide Confessions does not publish dosing, sourcing or product recommendations.
What peptides improve skin quality?
GHK-Cu is the most-discussed skin peptide (58 confessions on this site), and topical copper peptides have some small human studies on fine lines and firmness. Cosmetic signal peptides such as palmitoyl pentapeptide-4 (Matrixyl) also have small studies. Reports of skin improvement from GH secretagogues are anecdotal. Melanotan is a tanning compound and carries mole risks.
Does GHK-Cu actually work for skin?
Community accounts are among the more consistent in the skin category — GHK-Cu produces positive reports at a higher rate than most topical compounds discussed in peptide communities. Topical accounts describe improved texture and hydration within 4–6 weeks. Injected GHK-Cu is not approved, and confessions describe lumps and site reactions. The mechanism (collagen and elastin stimulation, antioxidant upregulation) is supported in research-aware accounts. No community accounts describe GHK-Cu as producing dramatic overnight changes — the framing is consistent improvement over weeks rather than acute effects.
Is Melanotan safe for tanning?
No. Melanotan II is not approved anywhere, and regulators including Health Canada have warned against tanning injections. Its first-use nausea and flushing are well documented; the bigger concern is moles — darkening, new moles, and case reports of melanoma. Any new or changing mole needs a dermatologist.
Topical vs injected GHK-Cu: what reports describe
Topical GHK-Cu is a cosmetic ingredient in serums and creams, used as the product directs. Reports also describe injected GHK-Cu; injectable copper peptides are not approved, and confessions include lumps, site pain and discolouration. This site does not publish injection amounts or schedules.
Can peptides reverse skin aging?
Reports describe gradual improvement in texture and fine lines rather than reversal, with the largest changes described by people starting with sun damage or loose skin after weight loss. Several reports describe no change. The best evidence for skin aging remains sunscreen, retinoids and medical treatments; peptides are an add-on at most.
