Well, I think the product is definitely worth a try. It a pretty simple formulation. Oh yeah, apparently more is not better with bulbine natalensis. It can actually lower testosterone if you do not follow directions.
Many of these herbs are in my Aggressive Strength Testosterone Booster. Yes I have a vested interest in this recommendation and thus I am no doubt biased. However, that does not mean my testosterone booster is not effective. Obviously it is in my best interest to sell a supplement that actually works and Aggressive Strength definitely works for most users as I only have a 2% non responder rate. Just look at the endless testimonials for more support and decide for yourself. Check out Aggressive Strength Testosterone Booster Feedback
