Testosterone Cypionate is a single-ester, long-acting form of testosterone. Due to its ester length (8 carbons) it is mostly stored in adipose tissue upon intramuscular injection, and then slowly but very steadily released over a certain period of time. A peak is observed after 24-48 hours of injection and then a slow decrease, reaching a stable point after 12 days and remaining there for more than 3 weeks. A long acting testosterone ester may be the best for all your mass building needs, but it is not an easy product to use. Nolvadex and Proviron will come very handy in such cases and after the cycle. HCG and Clomid or Nolvadex are also required to help restore natural testosterone. The frequency of side effects is probably higher with this type of product.
The aromatization rate of this type of testosterone is quite large, so water retention and fat gain are a given and gyno can be a problem. If problems do occur one is best to start at 20 mg of Nolvadex per day and stay at that until the problems subside. I wouldn't stay on it for a whole cycle as it can reduce gains. Testosterone is one of the few compounds where Proviron can actually be preferred over Arimidex. Proviron will not only reduce estrogen and can be used for a long time in a testosterone cycle, it will also bind with high affinity to sex hormone binding proteins in the blood and allow a higher level of free testosterone in the body, thus Improving profits.Typical side effects may include nausea, acne, excitement or increased aggressiveness, chills, high blood pressure, increased libido
