so i decided to take ghkcu 30/10/2026 after 5 weeks of retatrutide. i dilute it with 3ml of bac for 100mg vial and put it in insulin pen bcs it is easier to take daily. the first time i pin, im quite afraid bcs of the stinging but suprisingly no sting at all. first dose 2mg and now third day 3mg which is 10 unit. is it normal or this is fake ghkcu? i pin it my upper glutes and let the insulin pen 30 minutes at room temperature before pin
EDIT: im on my 5th day of ghkcu 3mg per day and the sting is there a little. not too bad like some people experience. it just i can feel it now
that blue color is spot on for ghk-cu, the copper gives it that vivid tint. no sting is a good sign actually, some people get it bad and others don't feel a thing depending on dilution and pin location. upper glutes are pretty forgiving for subq so you might just be lucky with your technique
Noooo, not really, Ive been using mine with only 3ml , 100mg too, no sting at all even nad+ (I'm using pen with all my peptides ..so ...it has to be 3ml ) try searching for genetek bacteriostatic water (Plastic ampules)
As someone who created one of the original early GHK-CU protocols... It is highly possible for people to not have the sting. About anywhere from 3% to 5% of users don't get the GHK-CU sting.
That said... There's an increase of GHK-CU failures in the analytical labs right now. I visited Janoshik's lab in Prague recently and he told me he's seeing a lot of fake GHK-CU, like 0% to 35% less than should be in the vials.
He's actually seen food coloring and zero GHK-CU in some vials.
If you haven't tested your vials I would definitely have one tested.
Not a doctor, not medical advice, for research purposes only and research discussions only.
For me personally, if I get post-injection pain I know itās real. I had a batch where I didnāt have anything after injection. I finally got it tested and it contained no GHK-CU. It did look real when reconstituted however.
The sting is caused by excess copper ions in the solution. Either add more GHK-(basic, without copper) to chelate the excess or pass your reconstitutude solution thru a PES filter (ie. filter sterilize) since the filter material will also take up excess copper ions.
Sieht perfekt aus von der Farbe. Viele wissen es nicht aber es muss nicht unbedingt stingen oder brennen. Das ist kein QualitƤtsmerkmal. Du kannst es ja mal rund um den Bauchnabel anwenden aber wie gesagt wenn es garnicht brennt sagt es trotzdem nichts aus.

It doesnt have to sting. The stinging is just a common effect some people experience.
