I bought one vial very early in my own peptide use, right when I picked up a couple other single vials before discovering this group. It remains un-mixed in the fridge and I'm increasingly thinking I won't use it because it doesn't seem worthwhile. On the other hand I combine another compound with tirzepatide and it works well for me. Maybe consider that option instead.
Just sharing an experience as a data point on this compound. I began with a very small amount last week and right after the shot went to sleep only to wake up with intense itching on my forearms and hands. It seemed odd but I figured it could be from pollen since I had spent the day outside and didn't connect it to the injection at first. This week I took an antihistamine ahead of time as a precaution before the next scheduled small dose. Even so, my eyes quickly became so itchy I checked them in a mirror though they showed no swelling. Then today the last straw hit when I felt completely flattened as if a truck had hit me twice, leaving me unusually exhausted. I'm not going to risk a third try. Looking back I should have spent more on one vial when testing something new to me. An AI mentioned that only a small number of people in the original studies had similar issues.
