What makes HydroTest Designer Pro-Testosterone so valuable and unique? First of all, it's far more effective at maximizing active usable testosterone than anything that's ever been on the market. Furthermore, unlike prohormones, HydroTest does not decrease your body's own natural testosterone production, and therefore will not become ineffective over time. HydroTest delivers the strongest and most effective dosage and form of Tribulus Terrestris in the entire supplement industry - a colossal 40 mg of Liquid German Tribulus Terrestris, composed of 80% Protodioscin. Such purity and potency is unmatched by any other testosterone-enhancing formula ever to hit the market. That alone would give you everything you need to pack on slabs of lean muscle mass naturally, and boost your sex drive beyond belief, but Nutrabolics doesn't stop there in the pursuit of perfection - HydroTest also includes 500 mg of a powerful, one-of-akind Designer Pro-Testosterone Complex. This complex synergistically combines the purest and most potent extracts of the strongest testosterone-enhancing herbals, Eurycoma Longifolia, Avena Sativa, Fenugreek, and Rhodiola Rosea, to complete the strongest Designer Pro-Testosterone Formula ever created. HydroTest also utilizes a unique Nutrabolics patent-pending Liposmal delivery system providing the highest and fastest absorption rates humanly possible.
