Curious about the sleep mix.. wondering if anyone else has had this experience. It stings and hurts so bad that the first time I did it I thought I hit a muscle. It hurts so bad going in and there was a knot and welt for a week and a half. I waited a week and a half before I tried it again and I tried two different places and I couldn’t even finish the shot because it’s stung so bad. Am I doing something wrong? I am not new to peptides at all. I take glow that stings a little because of the copper and sometimes it’s red and sore for a short time and other peptides as well. Pinning has never been a problem. I would love to be able to use it so if anybody has any suggestions, I would love them Side note.. the epithalon worked wonders for me. I have been sleeping for about six weeks consistently, which I have not done since I was a child. I wanted to be able to take the sleep mix when I cycled off of it.
