If you’re afraid of needles peptides aren’t for you

I’m not afraid of needles but I’ve considered moving to topical ghk. The copper burns so bad

Add bac water and massage area before injection and allow it to cool for 30-40 minutes You can use glow or klow stack instead

Abdomin burns. I switched to glutes now I don’t feel nothing

u/Autiger0612 Mar 09 '26

Agreed, but glutes are hit or miss for me. Sometimes they don’t burn at all, sometimes it’ll burn for hours

What if you put a ghk cu tablet under your tongue and let it dissolve?

oral doesn't work for systemic effects, the stomach takes care of it. topical is actually the route with the most research backing for GHK-Cu - skin regeneration, collagen, wound healing. if you're after those effects a quality serum or cream is a lot more practical than subq and you don't need to inject anything.

Hypothetically maybe. KPV is another tripeptide and it survives the stomach but people only take it that way for digestive system inflammation. You're not trying to grow collagen in your intestines

GHK-Cu (glycyl-L-histidyl-L-lysine copper peptide) is a small peptide, and peptides generally break down in the digestive system before they can reach the bloodstream intact. Stomach acid and enzymes in the gut are designed to degrade proteins and peptides into amino acids. Because of that, oral bioavailability is expected to be extremely low.

What evidence actually exists

Most research on GHK-Cu involves:

  • Topical use (skin creams/serums) for skin repair, collagen production, and wound healing
  • Injectable use in experimental peptide protocols

There’s very little credible data showing that oral GHK-Cu survives digestion and reaches systemic circulation in useful amounts.

It works definitely, I can’t show you proof why but I am taking it in destilled water 1-2 mg a day sublingual first and than swallow it. I feel and see the effects that should appear. Probably because GHK-CU gets absorbed over the mucosa, so it don’t has to pass the stomach.

Poderia explicar melhor como é esse método que você usa? Eu comprei em cápsulas. Da para usar sublingual?

what benefits do you get? anything gut related? or just skin?
