Overall, my stack was amazing! I can only speak for recomp purposes as that is what my aim was and it did not let me down. I had consistent increases in strength and endurance while weight training without any negative sides. This isn't SD and doesn't claim to be, but I experienced loss of bf with increases in strength to a degree that I haven't been able to achieve with diet and exercise alone. The last PH that I used was epistane and the lethargy that I got with that was horrible, including rise in bp that kept me from using any stims or pre-workout drinks. 5aOHP though didn't increase my bp at all and worked very well with pre-workouts.
My only complaints would be that I ended up needing two bottles since I ran the dosage a bit higher, but that is what worked for me and honestly I can't say I wouldn't have gotten the same results with one bottle's worth. I just wanted to be sure so I ran it high. I'm also not a fan of having to deal with the oral syringes. A dropper-type package would have been nicer and less messy, but it's not that big of a pain to use the syringes that I wouldn't use a product just based on that.
I would definitely recommend picking up the 5aOHP and 7-KE stack before all of the 7-KE is gone. Used together with a clean diet and training routine, you will see some really nice results.
