I recall. I put 3 ml test e 300 in my quad and was debilitated for a month. Turned into cellulitis eventually. Got to the hospital when I realized what it tuned into. Started as pip... Was no infection found, just major inflammation
And I've done 1.5cc of test 500 with no issues...
But my buddy couldn't handle .5cc of test 500
I just believe everyone tolerates different esters different.
