I love Popstar! Currently 2 bottles in, about to order a 3rd. For me, it took about 3 weeks to notice a considerable difference. The biggest difference is how far I can shoot now, with volume being moderately affected. However, neither myself nor my partner really noticed a difference in taste, hence the 4 star review. Everyone's body works differently though. Thanks for the awesome stuff!
(P.S. The flavor of the pill has oddly grown on me!)
