Well, I think it would be a problematic comparison if not defining what one means about what oxandrolone will do, however the article did define that.
You will find some individuals that have very good results from oxandrolone: but for that matter I know two men that got quite good results from 12 mg of Dianabol per day (it was an odd Dominican Republic product with 3 mg/tab instead of the usual 5 mg.)
But in general, the great majority will see absolutely nothing from that. However, someone who did may object to any supplement claiming to perform better than their 12 mg of Dianabol, even though any supplement that does anything would do better for most men than such a low dose.
There are many scientific studies showing modest dose anabolic steroid usage – and 20 mg/day, 140 mg/week is definitely modest usage – showing no significant gains.
Myself, 75 mg/day oxandrolone does little, if by itself. Well, except promote aggression: anger in traffic and once at the Post Office. But muscle gain, nothing much.
But the Carbolin 19 article does not leave it up in the air as to what amount of gains is being compared to. It gives the exact figure from the oxandrolone study in question, gaining 3.9 lb LBM while losing 7 lb of fat in 12 weeks. Carbolin 19 can do better than this.
But if one thinks oxandrolone to do much better than that figure, well, then Carbolin 19 may not do what one thinks of oxandrolone.
I tend to expect that a lot of this result, regular forskolin beating 20 mg/day oxandrolone in this regard, had to do with diet. Anabolic steroids aren’t best suited to gaining LBM at the same time as losing considerable fat mass. Great for retaining LBM under those conditions, but not for gaining much. You have to eat to gain if wanting to gain muscle with anabolic steroids.
I really wouldn’t expect many men using only 20 mg/day oxandrolone to gain more muscle mass than in that study while losing that much fat. The study looks about right to me.
Btw, if your comparison was going to be to being on a bulking diet, I suspect the oxandrolone would appear in better light. But that wasn’t the study that was done, and Carbolin 19 wasn’t being promoted as a bulking-phase agent. The article was pretty specific.
For a lot of people it’s great to lose fat and gain muscle at the same time, instead of in sequential phases. Forskolin is good for this, and Carbolin 19 does better than forskolin, most likely on account of its much longer duration of action and better bioavailability.
