If you live in the U.S. you will not find Testosterone Cypionate for sale on the black market as commonly as you will many other testosterone forms; especially when it comes to pharmaceutical grade. The vast majority of Testosterone Cypionate is manufactured in the U.S. by Upjohn and Watson, and very little ever finds its way to black market suppliers. Of course, outside the U.S. things begin to change as there are quite a few pharmaceutical companies that make it. Further, numerous underground labs across the globe manufacture the product.
Regardless of the brand you choose, most Testosterone Cypionate comes dosed at 200mg/ml or 250mg/ml. There are a few exceptions; however, most high dosed Testosterone Cypionate normally falls under the category of buyer beware. Such products are commonly under-dosed and are only provided by low-grade underground labs. Of course, regardless of the dosing, you must be very careful when making any anabolic steroid purchase. Contaminated products are not uncommon, and when it comes to human grade Testosterone Cypionate this is one of the most commonly counterfeited testosterones.
