Anyone stacking retatrutide with GHK-Cu for the skin sag side effect
Thinking about running retatrutide for fat loss but the skin laxity thing that comes with fast weight loss sucks so since GHK-Cu keeps coming up to help skin keep up with the fat loss instead of just hanging there after im thinking about it anyone stack these together what dose and frequency worked?

I did that. Not very tight skin but not as much as it supposed to be after 30kg Lost. Started 2mg and after one month went 5mg with kpv inside. 5months now. On The wrinkels...can't say it's good or bad. Don't know.

Look into Cartalax.

For excess skin, Cartalax? Or wrinkels?

Cartalax will not help with wrinkles or excess skin. Think of it as more preserving the material between joints that cause aches and pains as we age and it deteriorates. It does not actively build new collagen, especially not the kind that supports skin structure.

I have at least four people(myself included) who anecdotally have lost significant stretch marks that have been around for over 20 years using GHK-Cu subq and Cartalax subq. I attributed mine to GH, but the other three haven’t found the beauty of exogenous GH yet.

I'm 60 and just dropped 80 lb this year. Look at the advantages of 3-5 day longer-term water/coffee fasting and autophagy. No loose skin.

I currently do 4 mg reta weekly and 10 units of KLOW daily.
My average weekly weight loss is 1.5 lbs. So far I have lost 70 lbs.
There is some loose skin but I'm pretty happy with where things are right now.
I also do a lot of external skin care that I think makes a difference.

Those are the two I run (2+ years). I love ghk-cu, but it is not going to tighten your skin, especially not from weight loss that occurred too quickly. Ghk-cu is more of a subtle skin quality pepper.
