end of cycle..

At the end of my cycle which will be at the end of june, i was thinking about using 2000iu of profasi mon, wed , fri for two weeks with 100mg of clomid. For the following 3 weeks 50 mg of clomid.
I've done alot of cycles this year,with not much time to recover so i need something strong!
Can i use proviron to keep my libido up or will it interfere with my recovery?
I've read in some articles that you can 'cause prov. doesn't harm your system and in other articles its a definate "no".
Which is correct?, a bit of info would be really helpfull, thanks guys.
