Huh? A trifecta IS test, deca and dbol.
anyway, masteron needs no test base - as it supplies the DHT which is the ONLY reason that test is used as a base in certain situations..
I personally cannot see the point of running mast with test.. increased aggression and strength but no real extra anabolism - you'd choose tren instead i think.
(If BR is right about tren not being progestinogenic, but just causing too low a estrogenic level then mast might not help with the sex drive alone... as SOME estrogen would be necessary.. mast, tren and eq? nope - you'd just use tren and test again. Its a puzzler, and i am rambling!)
Proviron, Testosterone and Masteron can all be used for the purpose of DHT.
Obviously proviron is useless an an anabolic but i have run many deca and prov cycles where libido stayed solid and mood and everything was cool..
i remember my first deca cycle. 6 weeks of 200mg norma. My dealer suggested i might need proviron but i couldnt afford. by week 3 i was begging for it.
It provided the DHT or androgenic base that was needed.. (DHN being nandrolone's much weaker - and benefically so in its specific use - androgenic component)
