I wouldn’t use Proviron to boost sex drive during PCT–it will keep you shut down.
For what its worth, I used Mikekatz’s PCT protocol (2 week alternating cycles of Clomid and Nolva)after my last cycle. It was a great recovery; I maintained my muscle and strength and felt great, with good energy.
Normally yes, proviron post cycle is not a good idea. However in this case, since the shorter chained ester was the testosterone, using any source of DHT, whether it is more test, proviron, or even hcg will help things, since the decanoate ester is still causing inhibition anyways. I recomend you calculate the length of time that decanoate is going to be in your system for and still releasing greater or equal to 10 mg per day, and contine using your test, or even use daily hcg injections in small doses of say 100 iu. This will keep your testosterone high, while the deca clears your system. Also using clomid or nolva is a bad idea if you are still suppressed with the deca, as they will do absolutely nothing good for you. Both are ‘weak estrogen-like- hormones’, which cause estrogen like sides - one being moodyness or in some cases I’ve even heard of weepyness. So you have low test levels, plus elevated estrogen-associated effects, this makes for a pretty sorry mood. Now add in the fact that you are watching some of your gains fly out the window, and you can’t get it up either, well that explains whats going on right now.
So the sollution is Hit the test right now, as it is hopefully still at your disposal, do at least 75-100mg per week untill that decanoate is out of your system. If you have hcg, use it in small doses instead of the test, But whatever you use, don’t use the clomid or nolva, use femara or armidex instead. Excess estrogen hanging around post cycle, weather blocked or unblocked is going to slow down recovery, and put you in a bad mood.
