this is a result more so of the specific gear you used. I would avoid local made stuff and go with high quality. There are a number of reasons this could have happened. Basically don't use that brand again. If it was a high quality lab, it was possibly a solvent they used that you are allergic to. If it was a local smaller lab, it may have been a contamination. Pick one of the popular brands from Naps and you should be ok.  You could also try test cyp instead in case it was an allergy to the E ester.
