Honestly, not really, I can tell you their name if you wish, but the reason I ask is, most side affects and tell tale signs that I have read on the internet about IGF do not go with what I experienced, but I did see results, I just wonder if there is something else in it, my first experience with this IGF-1r3 seemed good, I was sick for a while still training but not making any gains I actually lost alot of weight, and when I recovered I wanted to get back into it full swing and thought id give IGF a try, shooting 50mcg everyother day I boosted my weight from a lean 165 to a thicker 182 in about a month I was eating good food but a lot, the weird thing is I am very lean always have been, if I am training I can eat a truck load and gain very little especialy if I am training hard but the weight just came on and fast, I admit I put fat on mostly around my gut but in the two months after, I hiked around mexico for a month and a half, didnt train besides push ups and situps and leaned out, now I weigh 170 and I am quite abit thicker in muscle, could I be insulin sensitive? perhaps I was taking too much igf-1 and thats why I got fat over that period? now I look and feel as lean but I am about 5 pounds heavier, I realize this reply is a complete mess sorry about that
