I've done tren only cycles several times with great results lost fat, gained strength,and added good bit of weight as well. I'm lucky though it doesnt shut me down at all and i gone as long as 12 weeks on it. But the thing with roids is they affect people different something that wont shut you down or give you gyno may very easily give someone else those same sides effects even at low doses. I would suggest trying it cause if you made your own tren its a very cheap cycle just make sure to have post cycle therapy (pct) planned out and have either B6 or bromidex(I believe thats right...I get by on B6) for the gyno that may happen due to the tren bc nolva will do nothing for it. Anyhow i hope this helps.
