will give you better fuller pumps in the gym , will lower your blood sugar, and make you a bit more insulin sensitive which can help with fat loss . needs to be ran 4 weeks on then a few weeks off . don't expect a lot of size from it , unless you were planning on running it with a synergistic stack of other compounds and long term (6+ months).
Tren produces a lot of IGF1 itself . You'll get more size running tren and the benefits of IGF production , far more then just running a peptide solo.
