I've done trenbolone a couple of times. I'd say 100mg EOD is enough to see some nice results. For sides I must say this is the worst steroid I've ever used. Night sweats, insomnia, my nuts schrunk and constipation. I can't run it again because I had massive problems with PCT - post cycle therapy - even though I ran HCG - human chorionic gonadotropin - , clomidand Nolvadex.
I actually think this is one of the most dangerous steroids out there. Worth it, no. I rather go with a low dose of Dianabol - methandrostenolone - and Test + Equipoise - boldenone undecylenate - .
If you would get problems with the PCT, go for a PCT with Dbol(5-10mg in the morning for 60days), it might help as it did for me(I was on too much shit for too long).
Positive results with Tren would be: Pumps like crazy, fatloss like crazy, good strength gains and also pretty nice muscle gains.
