If you have a powder source test is pretty cheap but I'm talking about the average guy a month ago. You could get 4-ad cypionate for about $2.50 a gram. I haven't had experience with gym prices in years but guys were paying $10.00-$15.00 PER amp of sustanon or testoprim-d years ago. It's a mute point now because of legality issues but I've seen blood tests of people on 1,500mg of 4-ad cypionate that were what one would expect from 750mg of test cypionate. Also, the rat levator ani assay's found it to be 80% as anabolic as testosterone mg/mg so it seems to have a possible intrinsic effect on top of the conversion. The whole concept of a "pro-hormone" was a marketing ploy. There are scientists who believe certain AAS's exert most of their action through conversion and metabolites, a-bombs being an example given. It's a lot more complicated than a conversion to an active hormone or not. If I had taken my 4-ad without monitering my body composition then I would probaly have considered it crap as well, not worth it for three measly pounds on the scale. However, the fact I actually lost two pounds of fat having raised my KCal's 15% while unintentionally reducing cardio, due to work rekated constraints, meant I saw a very substantial change in body composition. I also kept the gains after the cycle unlike the guy who raves about all the "mass" he's gaining on his a-bombs and ends up complaining after he drops the ten pounds of water he gained.
