A buddy of mine will use tren only and fuck like a pornstar. I've heard the same from others too. I've also heard the opposite from people.
I've run tren only before and had no problems getting hard...but sometimes had problems nutting (but usually only if I wasn't that into the girl). Oh, and I was getting laid plenty...by plenty of different ladies. Problem is I got sick of them too fast.
I'd throw the test in just in case though, since you have it.
1) Tren is a BAD choice AAS for first sycle
2) Tren wothout test on a first cycle is a BAD idea
3) Cabaser will not keep you functioning sexually - it will only enhance sexual performance - however you muust have cabaser on hand for prog gyno with tren
4) If you add test have an AI on hand (ie Aromasin)
5) A maintenance dose of test will not bloat you at all - its diet that will do that
6) You have had Gyno before yet you hav'nt done your research about Tren Gyno?
Protein! As much as you can if your a BB'er offseason and precontest. That aspect never changes for me. Its a responsibiliy that haunts me 24/7. If i get up and pee twice a night, i'll drink a protein drink when i get up each time. Isopure for me cus i do low carbs/keto precontest.
