Testosterone vs. Methasterone: Potency

[1976pianoman]

Is is even possible to compare the strength/effectiveness of test vs superdrol? Is there such a scale to use for such a comparison? I assume because SD has not been scientifically tested and documented, the answer is "no".

I understand they should be taken together and I am taking them together using the SD as a kickstart - but was just curious as to how they both compare.
