Good read PAIN....I just started a slin cycle. I use 4iu pre, 4iu post, and 4 ui in the evening. I take a table spoon of sugar with each shake, or dosing. So far so good. No bad sides and crazy good pumps. I did arms and they almost really did actually hurt bad after each set. The pain would go away and i was hella vascular and just bigger and fuller. I am starting a cycle in a couple days. So cant wait to see what this stuff does after i start.
