I've used SDMZ2 and 3.
Likes: Strength boost is definite, which in turn means you gonna put on some mass if eating correctly.
Sides: Low Back Pumps and Limp Dick when dosed at 2 caps a day, this at about the 3 weeks in mark, another time I did 2 caps on lift days and 1 cap on off days and didn't get these sides.
Results: You can put on some muscle with this product, no doubt, but to keep it you must follow run by continuing to train hard and eating correctly. Also consider a PCT if you are not on HRT.
