I would never characterize a drug or steroid as 'counter acting' another. I am not a believer in adding a drug or steroid to cover up another drug or steroid. to me that is abuse. this is why i do not agree with the premise of using high doses of testosterone to reduce sides, how does adding more steroids reduce sides? makes no sense at all and is just not true.
in this case the object is raising the amount of DHT (male sex androgen hormone) you are getting vs. the amount of DHN (what most people incorrectly assume are estrogen or progestin sides) you are getting. its about balancing it out.
since DHT is your sex hormone you need to make sure that isn't swamped over by DHN which is what nandrolones will convert to.
aside from that
proviron will help reduce estrogen and prolactin issues and is a muscle hardener.
its pure DHT
the downside is DHT does attack the hair follicles on your head and can dry out joints. so once again the idea of adding a drug to counter act another drug is proven to be moot. but with using a nandrolone i would rather lose some head hair then have my dick not work. its really up to you. sadly the younger generation cares more about their hair then their dick it seems. thats why you see 20 year olds using viagra these days.. when i was 20 you got laughed at for using ED drugs, now its considered 'normal' ..
