200 mg has been shown to give some joist relief. I like to run it at 300. But I wouldn't recommend running that much unless you bump your test to 500mg.
If you're a trt guy, I'd go with 200mg of deca.
So try to keep the NPP at or lower than my Test? I don't have any real joint issues right now. I just want to push my lifts without having to worry about something snappin' I feel like I am holding back; a bit too timid.
Npp and deca doesnt really effect your tendons. It works more on your joints by causing them to retain more fluid. Tendon strength comes from lots of working out...obviously muscle grows faster but it takes time to strengthen tendons up.
Had wrist joint issues for months and with 150mg week NPP it's gone.
