Iv'e got a question for some people. What do yall know about DECA. Ive been thinking bout getting on it sometime after this winny cycle. Ive heard it makes your fast twitch muscles better and i heard it makes your tendons like rubber bands. What do yall know about it?? Also do yall know if the injections are painfull and how long does it stay in your system??? Also how long is a cycle of it.
