Actually the most Anabolic Hormone in the body. Quite ironic that it's legal huh?
Anywho, if you follow the recommneded protocol of 10g carbs per 1iu slin I dont see you gaining too much weight. Some like to play it safe and go over the recommended dose but most after time try to find their threshold before going hypo.
As fas ar quality mass you can gain it with the aid of Slin combined with AAS and ultimately GH. But running it alone I don't see you gaining too much weight. I'm speaking from personal experience along with feedback from others. There may be people out there that will disagree with me and have gained tons of weight. I'd love for them to chime in...............
