Well, Deca is Deca. It's not unlike prop or cyp -- a short acting ester has advantages and disadvantages.
I disagree with Andy on several points.
The ideas touched upon by BigAndy were, at one point, concepts that I introduced. And in this thread, I could not have expressed these any better myself. So disagreeing with BigAndy is disagreeing with me, as I would have replied with the same remarks. So, if I may, disect your response a little.....
First of all, the statement that it takes 4-5 weeks to "stabilize" is pure fantasy. There's no such thing.
Replace "to stabilize" with "to reach (accumulate) maximal theraputic blood levels, following weekly doses." Of course, there is no such 'ceiling' mathematically speaking, but the practial concept of such an event is undeniable.
Actually, I agree that 300 mgs of Deca is more anabolic than 300 ms of test.
Moot point.
NPP will clear more quickly, but enough metabolites can remain to test positive long afterward. (If that's a concern) I can't say for sure if it will be as long as decanoate.
I challenge you to show me that NPP is testable long after a cycle like deca is.
At any rate, all the problems of Deca still exist.
I disagree. I believe the problems associated with Deca (as far as recovery of natural testosterone) result directly from it's ester. Without having any data, I would guess that users of NPP probably do not experience such problems recovering natural testosterone. Although I believe that mg per mg, nandrolone is more inhibitory than testosterone, I feel this is a non-issue a month or two after a cycle.
