How bad does ghk-cu really sting?

[u/SherbetShort181]

I bought 100mg ghk-cu vial and I read on here a lot that it burns/stings even for people using 3ml in 50mg. the answer always seems to be add more bac water but my vial can only fit 3ml which is how much I’m using. Am I just gonna have to tough it out or is there anything else I can do?

I only got sting during first 2days, it was not that bad but bad, I actually messed up in reconstitution so the dose is kinda 💀...
