i contacted the supplier and got the following answer back:
Non Methylated compound, Metabolite of the naturally occuring DHEA, potent androgenic effects, as this compound is non methylated it can (and is usually recommended) to be stacked alongside other compounds. Lean gains are to be expected with 1-androsterone, the gains are not usually noticeable for around 2 weeks , due to the non 17a and long ‘kick in’ time it can be ran for 6-8 weeks for the best gains. if stacking with another compound stick with a 4 week cycle. It should be noted 1-Androsterone is more geared towards users looking for an increase in strengh than a change iin physical appeareance.
So its 1-DHEA and NOT the thing you and probably me was thinking at first. This means you can do this product but you can also do AlphaMass which certainly has more reputation along the boards. Its up to you. I voted for the Mass AD because of a very good deal i was offered at the supplement shop.
