Have a lot of experience with slin. I'll take 12-15 iu pre workout humalog with or without 5iu gh daily and a gram of test over any other cycle or whatever over complicated shit guys run.
There are a set of rules you follow with slin and if you follow those rules and respect the slin you'll be fine. That's NOT a use recommendation for the noobs and lurkers. Some of you will do some really dumb shit just on a half suggestion from some guy you've never met. So don't use slin.
Last time i used it i went from 245 to 265 without increasing bodyfat in 6 weeks. I'll take slin any day over tren (poison).
Next time i plan on using pre/post training slin.
Also have a shit ton of lantus i got handed to me for free that i thought about trying one day a week but I'm not real big on the 24hr suppression idea. Tried it once at like 30iu and all i did was shit all day.
Slin is all about education/discipline and following rules. I researched and asked questions for around 2 years before i ever tried it. Was fortunate enough to have a great coach for a while that dialed my knowledge in even more.
But i digress... don't use slin.
