I went in open minded on taking this product because I had a guy that worked for pro supps kinda sold me on the product. The price made sweat a little because usually test boosters are more affordable. I noticed a difference in first few days because my sex drive increased but also stamina and strength differences too. It's a all in one product with estrogen supppresors dht blockers stimulates androgen receptors and test booster. Great pct but I don't like prohoromones so I use it as my basis for everything. Price is only bad thing.
