Peptide Critic Community

@uxu Awesome, thank you for the straightforward answer without being condescending to someone new at this. I appreciate it!

So I have never done any peptides and am slowly but surely taking my steps toward Retatrutide. I don’t plan on even starting for a few more weeks as I ask the questions and make sure I’m doing this right. I bought a V4 pen and the Novofine tips. My dumb question is, do you leave the tip in the pen for an entire batch and just use alcohol prep pads on the needle each time, or discard each tip after use?
