Outstanding for joints, you can flat out mask injury w/ it, but that aint good.
I remember the 1st few times I used it, It made me SO So hungry! Like sudden low blood sugar shaking hunger. At 600mg/ wk it shuts me down right now. And, I get no real added bennies going up from 200 to the 400 range, so I just throw 200 or so in w/ long acting Test a couple times a year.
I've used it to help rehab a nagging shoulder injury w/ great success along w/ light PT exercises. THis was a stubborn 6mo+ painfull injury that resisted EVERY other rehab method.
Keep the Testo dose double deca to avoid hardness issues where it counts, and cut out the Deca a bit before you stop the Testos is my method.
I'd never consider it alone. If you do, you might last 2-3 wks at a moderate dose before mattress rodeo cums to a abrupt halt.
