NPP vs Deca Shutdown; Dose or Duration?

**Kdub** · 12-28-2010, 08:32 PM

It is the dose that determines shutdown or duration or both?

Mg for Mg, would a very short Deca duration (1-2 weeks) shut a person down any less than 8 weeks of NPP?

No need to ask why a guy would run 1-2 weeks of Deca. Am asking to understand the shut down qualities of Deca/NPP family.

Duration is the more important factor from what I have seen. And even a single 200mg shot of nandrolone (doesn't matter what ester) will shut down your HPTA, so it mostly comes down to how long you have the compound active in your system.

Thanks Bon.

I used a small NPP dose (350 mg/wk for 4 weeks) last year having very little "Deca " experience previous and got shutdown. Ran an aggressive PCT at the end of the 9 week cycle and still felt shutdown for a long time after.

Makes me wonder if the ester regarding the nandrolones should not be viewed in the same light as with Test. I suppose the two are not really comparable seeing as nandrolone shuts down and Test suppresses, but even the latter is dependent too upon duration.

Returning your natural test levels is more difficult using nandrolone vs test via PCT even once the ester has cleared the system?

Another problem is that Nandrolone has metabolites that linger around LONG after the ester has cleared and the compound is considered inactive. So these metabolites likely make recovery harder as well.

So are u saying that deca shuts you down straight after 1 dose? and i read that you should wait 21 days after your last deca shot before starting pct however my question is in the 21 days when the decas leaving your system are you slowing loosing the mass you gained?

Yes. Complete HPTA shutdown from the first dose (this has been demonstrated in human studies using 200mg of Deca ).
And the Deca is still active and producing gains for most of those 3 weeks. So no, it isn't just downtime.

Ok cheers bonaparte
I have another question it may seem stupid however i will throw it out there what if in those last 3 weeks you run say dianabol to keep you going strong because you can begin pct 24 hours after last injection of d-bol? Then will you be maximizing your gains in the final weeks of a cycle?

Yeah, that's called backloading a cycle and is usually done with test prop and/or a cutting steroid like Winstrol .
