I've tried both and got decent results on both of them. I did use the v1 of AndroLean, but honestly it did not give me enough results to justify the cost. Natadrol does have some sides though. I got grumpy and lethargic, seemed like it was making me hypo, which I have read later it does. I'd take 4 pills pre-bed to counter that side. Also the bph stuff... it's for realz.
