T-400 is a testosterone blending a very high concentration that's long-acting and placed in an oil based format. T400 contains three different types of testosterone esters engineered for maximum efficiency and performance enhancement. In this formula athletes will find; Testosterone Cypionate, Decanoate and Enanthate. The idea is to create an extremely powerful blend of the most popular steroid esters to produce maximum results. All of these esters are also extremely oil soluble and this minimizes any chance for crystallization. Testosterone is one of the most popular anabolic hormones used in many steroid cycles. Athletes consider it amongst the most trusted for improving muscle size and strength. Athletes taking testosterone-based steroids also reported big increases in their sex drive and libido. An issue to watch for when taking testosterone-based steroids is its aromatizing nature. Taking an antiestrogen like Nolvadex and Arimidex can prevent any of the negative estrogen-based side effects which can occur especially when the medication is taken in high doses. When supplementing with testosterone-based steroids it also doesn't take long for the body to stop producing this hormone. As a result after you complete your testosterone cycle it's very important that you supplement using the right combination of HCG, Clomid and Nolvadex to ensure that your body can continue producing hormones once again and that all of the performance enhancement that you produced can be held onto in a permanent state. PCT should be performed for 3 to 4 weeks after the cycle is completed. T-400 should be given in doses once a week in 250-1000mg each week for men. Women should not use this product.
