Review: This is LEGIT! - I’m gonna be honest, at first I thought it was a bit of a placebo but, this is legit. I used it on the tail end of my prep and it was an absolute game changer. Within literally 48 hours after taking it I noticed a lot more hardness and dryness. Sleep was deeper, mood was better, and energy throughout the day was amazing. Highly recommend
