This topic has come up before. It only burns if the eye of Sauron catches you using it.
Hey everyone, first post outside the newbie area so let me know if I'm stepping on any toes. Getting ready to begin with GHK-Cu to help with hair and skin while on Tirz. I've seen that swelling, redness, and burning at the injection site are pretty common. Diluting with extra BAC water is one suggestion I've come across, but I'm wondering what other approaches people have found useful for cutting down the reaction.
