i think if you read some more of the threads you will realise that they are talking about igf-1 when they say don't buy it preconstituted.Originally Posted by jcam222
MR sells long r3 igf-1, which is different and apparently more stable than igf-1 and so can purchase preconstituted. people haven't been having any problems with it. longR3 is also more potent.
stuff seems to be good pct, by itself, stacked...just make sure you take it with chicken.
