You're all a bit off-base.
In as far as fat-burning is concerned, progestenic-based
steroids(Deca/Fina) are better than estrogenic-based
steroids(Test/EQ/dball and so on).
The reason is that progestenic based steroids increase
the amount of the GD6P glucose transporters which
increase glucose oxidation.
Estrogenic based steroids on the other hand decrease
the amount of GD6P glucose transporters.
Simplifying this even further, all one has to do is compare
estrogen vs progesterone.
Progesterone is lipolytic while estrogen is lipogenetic.
In as far as DHT derrivatives are concerned(Winny, Primo
Masteron), nobody is really entirely sure.
