Personally I woudn't take Nolv UNTIL I start seeing gyno symptoms. Nolv can hinder gains to a degree. How much Dbol ar eyou doing to be running? are you only running dbol? Dbol works better when you stack it with another type I AS. Most guys do 20mg a day, taken anytime, (I usually take in the morning), but if you start seeing gyno problems, I have seen guys take up to 80mg a day just to get rid of lumps that stem from gyno. If you are looking for a good anti ester, I would stick with armidex. Nolv IMO should only be used IF YOU START GETTING GYNO LUMPS. Sure you can use it as a precautionary measure, but why not use armidex or liquidex instead. Armidex will not only keep more free flowing test in your body, but will also help with the bloat you get from AS converting to estrogen. Then use Nolv to counter off gyno if you start getting lumps. I took nolv very heavily (before I discovered armidex) and it hindered my gains big time. I have talked to several other BB and they have told me the same thing, that is when Armidex/liqudex was suggested to me. Low and behold I tried it and it works. Now keep in mind I am not saying that you shouldnt' do Nolv, (always keep some on hand just in case), but armidex and liquidex by far IMO is a must more effective product to counter act gyno.
