Yesterday biceps was in my workout and I injected tren and test enanth into my bis a few hours following it. During the night I felt incredible soreness in my bis and I still feel it today. It feels like lactic acid soreness so I like it since that pain usually means I did a good job on shocking the muscles. Anyway, I was wondering if the damage to the biceps from the needle could actually enhance muscle growth and that is the cause of my muslce soreness? Does anybody think that your biceps could benefit from lots of needle poking that damages the muscle so it has to repair and re-build?
