Same. I have a batch of Cephalexin just in case though I won't hesitate to seek real medical if needed or concerned.
This and bad reactions in general are also reasons I don't like experimenting. No high mg concentration gear, bb/ba at standard levels regardless of compound, cotton/grape/safflower/MCT. I've done enough to know what works and blowing up a blast/cycle is simply not worth it to me. Been there, done that, I own it but don't want that road again.
Another rule I have is to always keep pharma ancilliaries on hand. Nolva, Aromasin, prami etc. Not a regular user of many (never touched Nolva and prami hasn't been used in 6 or more years) but if there's an acute need it's there and I don't want to fuck around.
