I can tell you that n2slin is without a doubt my favorite n2bm product. take 2 tabs before your 2 largest meals of the day. it will prevent fat storage and your muscles will feel fuller.
as someone who is insulin resistant already, taking n2slin has helped increase my sensitivity, which means i can still get in my carbs for energy while not worrying about fat gain. it is a must use on tren especially, since tren does increase insulin resistance.
