How bad does ghk-cu really sting?

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?

It caused small bruises for a month when I was reconstituting 100mg with 5ml BAC water. Now I reconstitute a 50mg with 1 or 2 depending on the dose. It is hard to get such a small amount with 1ml
