i have used this product. i was selected to try out their "ultimate mass stack" kit which included stakabol, winabol, sterolbol, xabol.
stakabol is a bulker.
winabol is a cutter/hardner.
sterolbol & xabol is for pct.
you must not of looked very hard, because I have a thread about these products. particularly stakabol.
anyways, long story short. it is good to go. solid product, though I wish it didn't have the nac, ala, or milk thistle in it. but its a good bulker.
the combo of the three ds's work synergistically, which is why you dont need as much as you would if you were taking the compound by itself.
2 caps e/d gives you a total of 20mg sd + 20mg pp + 50mg hd. weight and strength gains are decent with this product.
I liked decabolen (old version) better though.
also, this isn't a product for a beginner. it will cause sever shut down, lethargy, and no sex drive. by week 4 your nuts will be the size of small grapes.
