Well, the Nors are the ones that I haven't heard too much on or just not too good. Below is a quote from Edog in a thread not to long ago, when I asked him about how his Nor injects went. I have heard mixed reviews on the 4AD and 4AD cyps. I think if I do one, eventhough 1-test is harsh (still debating) I'll probably just do the 4AD in a trans along side it.
"The Nordiol Cyps are onyl good for a 3 on 2 off cycle IMHO. They peter out after 2-3 weeks due to enzyme depletion it seems. They are useful if you cycle them correctly though and good gains can be made, but you can't do a straight 8-10 week cycle. I wish it wasn't the case, but I frontloaded and kept using high dosages cuz I have so much of it around. It did about the same as my 600mg 4-AD Cyp cycle, three weeks of nice solid gains and then nothing. I wish I could tell you it ROCKED, but it didn't. As I said though it could make a great year round roid, kind of like the old T-Mag never ending cycle article.
