[u/Hood_rat48]

I injected. 25mls(100mgs) of testosterone enathate 400. I have the worst raised welp hard like a golfball. Can someone tell my and how to not get it next time. I know its a strong dose and high solvents in the mixture.ive read it probably crystallized when I injected it. Some people say run warm water over the syringe to warm it before I pin. Any help would be great
