First I would like to say im a real moron.
I am currenty almost in week 3 of my PCT..
I just competed in a Deadlift challenge for reps. [405 lbs] I hit 18x. This was saturday.. Ate real well sunday felt strong today.
So I go to train legs today. warm up then start with front squats. 135,225,315,315,225. Felt strong. Then stiff leg deadlifts. 135,225,275,315- all was well and THEN on the last set i dropped to 225 to do some high reps and about the third rep a feel a snap! It felt like the muscle just tore apart. So i racked the weight and Iced my right hammy. right now its not in real pain, it feels more stiff then anything,some minor pain. I just literally got home from the gym. Fueled up and im about to go hit it with the cold/hot water method.

I need help here from you more experienced people/gurus!!
WTF do i do?? Ive had stiff / semi pulled hams before but nothing like this i literally felt a snap. Am I in some real trouble here??

You live and you learn.. Lesson learned. While off AAS and especially on PCT your ability to recover is much much slower. So rest and take it easy.
