Just opened my second vial of tirz30, the first one wasn't vacuum sealed but I went ahead and used most of it anyway until I got an ichy red bump similar to a subq oil shot.. used it for about 3 weeks. Im not sure what caused the irritation as none of the other shots did, although this was the one time i didn't mix it with other peptides and hgh. Second one was vacuumed, its hard to throw away a $72 vial, I actually paid $45 for the black friday deal and used about 2/3. Probably not the smartest thing to do but the bump is going away gradually, had the bump for about 3 days is all. Anyone else have any irritation from Tirz?
