This is still very little information on this product?. All I have seen are reviews and the desciption of the product which is not very descriptive. Does it have to be converted?. It does not mention this anywhere. In the description it does mention it is a relative to 19-nor. I believe 19-nor products are just crap...Well except for the cyps of course. Maybe I just haven't used them for a long enough period. I read that nandrolone is really a "slow builder" so it takes take for the gains to come. So how does this product differ from 4OHN?. I have heard 4OHN compared to DECA-Durabolin(nandrolone deconate). Of course though, M4OHN isn't going to have the ester, so your blood levels won't be as high. Now the recommended dosage for DECA is 2mg per pound of bodyweight weekly.Of course you have got to figure in the weight of the ester. You can see by my post that this would lead me to ask a lot of questions...If these ph/ps products don't measure up to the steriods they are "related" to, please stop comparing them and causing confusion!. I understand what nandrolone is and how it is used, and deca is nandrolone with the decanoate ester attached..
