Excessive use of prohormones, in either too high of a dosage, or for many months at a time, can temporarily decrease your body’s own natural testosterone production. The Leydig Cells in your testicles simply stop producing testosterone. This problem can be combated by taking Vitrix in a dosage of 6 Liqui-caps per day. The Luteinizing Hormone stimulating power of Vitrix signals your Leydig Cells to quickly resume their activity and to start producing testosterone again. It can be stated that Vitrix is an ideal product for all athletes who are concerned about low natural testosterone levels due to prohormone use. Implementing Vitrix at the end of your prohormone cycle for two weeks will also assist you in retaining a maximum amount of muscle and strength. You won’t crash and lose hard-earned muscle due to a lack of endogenous testosterone.
