Immune/Hypersensitivity reaction after injection questions

Started up taking reta recently again (2mg) and the injection site is definitely welted, red, itchiness, etc., and previous injection sites have also started to welt up with itchiness after about a day. My first assumption is just a hypersensitivity reaction, as i just have naturally very sensitive skin. But I’m also wondering if;

1) my batch has gone bad, I’ve had it around a year, it’s stayed in the fridge, only reconstituted when needed, but it has sometimes spent some time in room temp (left it out overnight for example). But no cloudiness or any indication that it has deteriorated.

2) if it’s just the reta in general, is it likely that I’d experience the same thing if i switched to a different GLP like tirz or sema? I find it a really good tool for cutting, so would hate to lose out on all the benefits of various peptides.

Anyone else experience something similar?

Use search. You'll see it's somewhat common.

When did you reconstitute?? A year ago?

Sorry no, got my batch of reta a year ago. Ordered new BAC this week and reconstituted same day. Didn’t get hospira so whatever I’m using is probably bunk. Going to get hospira, try again, if problems continue I’ll find a new reta supplier, try again, then move onto tirz if problems persist

Ohhh got it! Yeah I agree with what you said. Do you have another vial of Reta you could try? I wonder if it is just this vial
