I tried slin for the first time early this year. I found it VERY easy to gain size while on it(along with test/Dbol). I DID gain fat, although I wasn't eating completely perfect because I would get so hungry on it it was hard to not eat any fat and to only eat the exact number of carbs per iu etc. At no point did I go hypo or think I was gonna die or any shit like that. I would sometimes get an overwhelming wiped-out tired feeling, similar to how I might feel after like Thanksgiving dinner or something, that was kinda weird. I had to diet a little after and the fat seemed hard to get rid of at first. Comments I've heard are that I look thick, and that my traps look better. Next time I use it will probably be a small dose with HGH post workout. I've done HGH @ 4iu/morning, and wanted to try slin alone too before I use them together.
