So I have ran two cycles of tren before with no problem. Both of those were with tren E and never with tren ace!!! My first pin was okay but my second and third shots swelled up like crazy and itched like a bitch. For first time users of tren ace DO NOT FREAK OUT!!!!!!!!!!!!!!!!!!!!!!! THIS IS A NORMAL SKIN ALLERGY TO FINAPLIX!!!!!!!!!!! Cattle as well a humans can have allergic reactions and it is not uncommon to see cattle with rashes on their hide at place of implant. If I'm not mistaken and I may very well be!!!! Tren Ace is made from finaplix tablets vs. Tren E is made from powder. I think this is the reason I never had any problems with tren e. It should be noted that people with higher BF% have more of a chance of developing an allergic reaction. From my own experience, rubbing and adding heat only made it worse. Do the opposite, apply a cold pack and alot of benadryl cream. It usually takes a week for it to clear up. Just to be clear tren rash swells and turns red and gets a bit warm but it does not have a puss filled center. MRSA (STAFF INFECTIONS) will swell up like pimples and have a puss filled center and will also hurt like a bitch to touch SO PLEASE DON'T FREAK OUT!!!!!!!!!!!!! Hope this helps any one experiencing the same issues.
