2-alpha : ANYTHING SIMILAR??

A few years back, I ordered a product called 2-alpha from bulknutrition. With this product, I saw the best gains of any supplement by far. I was wondering if anyone knows of anything similar to this, or if a clone of this product exists. My body really responded well to it. I have around 20 caps left, and after that it's gone forever unless I can find something comparable or better. :( The exact ingredients are as follows:
2alpha, 17 alpha dimethyl-17beta
60 capsules per bottle.
Any help/info/suggestions would be much appreciated.
Thanx!
