Testosterone Propionate is one of many variations of esterified testosterone, which today's market brings. It's an injectable substance with the slow pace of the release due to connection of long enanthate ester to testosterone per molecule .This change modifies the liberation and half-life of testosterone. The difference in half-life and the release rate of testosterone enanthate and cypionate is negligible and the difference is only 48 hours. That is why these two substances are easily interchangeable. The interest here lies in the fact, that especially among American athletes and bodybuilders, the tesoterone cypionate is more popular than ethanate despite that neither of these is more advantageous than the other. Non-esterified testosterone has a very short half-life, so that its use is very inconvenient and impractical. Cypionate ester extends the half-life of testosterone to 12 days. Testosterone itself is considered to be the most natural and safest anabolic steroid. It can be used by any person as a natural testosterone in the body. It is the most versatile and flexible as to its intended use in cures aimed at definition as well as the volume period. Testosterone is the building block of all anabolic steroids, and it is a hormone naturally produced by the body. Testosterone is secreted by the testes and is responsible for the development or maintenance of a balanced primary and secondary sex characteristics in men - deepening of the voice, the rapid growth of the hair (especially on the face, legs and pubis), and also is responsible for the production of sperm for sexual reproduction. Most of anabolic androgenic steroid are derived from this hormone and, therefore, are used for improving the performance and produce significant gains in strength and muscle mass. The use of testosterone is associated with dramatic and almost permanent gains with respect to the muscle, the muscle mass and size, strength, aggression, endurance and the ability to handle intensive training. This hormone is vital for bone density, volume and muscle strength, sexual desire, body fat distribution, production of red blood cells and sperm production. Testosterone also acts as prevention of osteoporosis, and is important for physical health and wellbeing. Moreover, the hormone is also of use to stimulate linear growth and bone maturation. It regulates cognitive and physical energy and the maintenance of muscle cells. Testosterone also has the ability to reduce the risk of cardiovascular disease. Testosterone is considered to be literally the original anabolic steroid that is produced naturally in all humans and in most animal species. For this reason testosterone is considered to be the safest anabolic steroid. The body of each individual is already accustomed to the effects of testosterone.
Testosterone cypionate is subject to the action of the enzyme aromatase in the body, so the side effects are the side effects of estrogen. The rate of aromatization is directly related to the amount of used substance, and together with increasing doses aromatization is higher. Estrogenic side effects include: excessive water retention and bloating, elevated blood pressure (e.g. due to water retention in the body), accelerated fat deposition and gynecomastia. The side effects of estrogen can be reduced or completely avoided by using aromatase inhibitors or SERMs (selective estrogen receptor modulators. Among androgenic side effects are: increased secretion of sebum (oily skin), acne (in terms of increased secretion of sebum), body hair growth, and increased risk of inducing male pattern baldness (MPB) in persons with a genetic predisposition. Anabolic / androgenic steroids can have deleterious effects on blood cholesterol levels. This includes a tendency to reduce HDL (good) cholesterol and increase LDL (bad) cholesterol. All anabolic steroids have the ability to suppress or shut down the natural endogenous production of testosterone in the body, and Sustanon 250 is no exception. After the end of the cycle, it is highly recommended to use a suitable PCT (Post Cycle Therapy).
Beginners are recommended a dose of testosterone enanthate in the range of 300-500 mg per week. Even at the lowest dose range the substance provides a dramatic improvement for beginners, for the figure ad strength, provided nutrition and training are properly adjusted and strict. Intermediate users dosed testosterone cypionate in the range of 500-700 mg per week. Advanced users use the amount in the range of 700 - 1000 mg per week. To maintain a stable plasma testosterone levels, it's advised to use testosterone cypionate at least 2 times a week in regular intervals. Testosterone cypionate is detectable in urine for 120 days.
