I have enan in my cycle and I can tell you that that stuff leaves you sore for days and days. BTW I have the 10ml bottle and have heard the jugs hurt too but I didnt think the pain was this bad. I love my results and will suck it up and drive on cause itll pay off at the end cause at the rate im growing with strength and size , I will be closer to my long term goal which is to be a strong mad beast that can max around the mid 400's on the bench . My max is 325lbs right now but when i get to closer to my goal i will shout it out on a thread.
