I have been doin a lot of research on protocols and plan to start slin at the end of the month with my bulk cycle. I'm gonna run 5-10iu depending on how my body takes it, but what blows me away is how little insulin that is. Seems like just a drop and couldn't do a thing. Haha. Obviously that's not the case. Just use to pinning 3ml at a time, hell I waste more gear than 5ius lol
