Stabilized GHK-Cu
PEPTINA · GHK-Cu FOR MEN
The peptide that fades hereditary dark circles.
You've tried every eye cream. Caffeine for puffiness. Vitamin C to brighten. Concealer to cover. None of them touch what's actually causing the shadow — blood vessels showing through thin, melanin-rich skin you inherited. GHK-Cu rebuilds those capillary walls. It's the only ingredient with clinical data on the mechanism — now in a 15-second, twice-daily roll-on.

Why it works where every cream you've tried quit.
MECHANISM
Capillary-strengthening, not pigment-targeting.
GHK-Cu is the only copper peptide with published data on capillary wall strength. Stronger walls = less blood pooling = less blue-purple shadow under your eyes.
NOT IN
No Vitamin C
Vitamin C neutralizes copper. We left it out.
AIRLESS + OPAQUE
Stays potent
Airless pump + opaque black bottle = copper doesn't oxidize on your shelf.
ROLL-ON
Cold steel tip
De-puffs the second it touches you. Fixes the long-term cause underneath.
Real men. Real fades.
"I got these from my pops, and he got them from his. Eight weeks in, the shadow is genuinely lighter. Brothers, this is the first thing that's worked on the actual cause."
"I've tried every caffeine stick out there. None of them did this. Two months on Peptina and my under-eyes look like skin again."
"Hereditary blue-purple shadow, visibly faded. People stopped asking if I was sick. Bare-faced and confident in photos again."

What should I do if I have allergies or sensitive skin?
If you have known allergies or sensitivities to any skincare ingredients, we recommend reviewing the full ingredient list before use. If you're concerned about a specific ingredient, feel free to contact us—we'll be happy to confirm whether it's included in the formula. As with any new skincare product, we also recommend performing a patch test before applying it to the under-eye area.
Aren't dark circles just genetic?
The thin under-eye skin is hereditary — especially in melanin-rich skin. But the shadow you see through it is blood (vascular), not pigment. Strengthen the capillary walls and the shadow fades. That's the mechanism nothing else in your routine is treating.
How is this different from a caffeine eye cream?
Caffeine constricts vessels temporarily — it reduces puffiness, not darkness. GHK-Cu rebuilds capillary wall integrity over weeks. Different mechanism, different result.
How fast will I see results?
De-puffing is immediate (the cold roller). The blue-purple darkness fades across weeks 4–8, with the full result between weeks 8 and 12. The 3-Pack is sized exactly for this build.
What if it doesn't work for me?
60-day money-back guarantee. Keep the bottle. We'd rather refund you than have you using something that's not built for your type of dark circle.
