Would you think that Trenbolone is 5 for mass gain, but Parabolan,a different ester is 9 for mass?
Or that one could keep all gains from Primobolan?Given a 10 there.
I can tell you from my own experiences with pharma Primo from a German pharmacie back in the 1990, that this is not the case.No way.
Guess this chart is based on bro science.
