With more and more people using bulking stacks and bulking cycles to aid them in gaining lean muscle mass, it is also important to know the measures used to prevent and to deal with adverse effects. This involves the use of on cycle support supplements as well as a post cycle therapy.
A steroid bulking cycle involves the use of steroids that have been shown to increase the rate of protein synthesis as well as increasing the oxygen carrying capacity of blood. A bulking stack usually involves the use of a combination of such steroids. The best bulking stack therefore contains steroids with very high anabolic and androgenic effects. A bulking cycle usually lasts between 12 to 16 weeks, depending on the type of steroids used in the stack.
During a cycle, even the best bulking cycle, there are physiological derangements that take place. For example, there is a reduction in the blood levels of Endogenous testosterone. To mitigate this, on cycle support with Testosterone esters is necessary. Testosterone esters do not stimulate the testes to produce Testosterone but they replenish the levels of Testosterone in the blood. As a result, symptoms of low Testosterone are not experienced – the best bulking stack 2017.
Post cycle therapy to cater for this foreseen side effect involves the use of Testosterone boosters and supplements. Testosterone boosters stimulate the production of endogenous Testosterone in the testes. Most of these supplements contain natural ingredients. An example is D-Aspartic acid. This amino acid when used in the diet stimulates the production of Luteinizing hormone and Follicle stimulating hormone by the pituitary. These 2 hormones give a positive feedback to the testes to synthesize Testosterone.
During a bulking cycle, the steroids used undergo aromatization by the Aromatase enzyme to Estradiol. Estradiol is notorious for causing water retention and man boobs. On cycle support involves the use of an Aromatase enzyme inhibitor. Examples include Lestrozole and Anastrozole. By inhibiting this enzyme, they reduce the levels of Estrogen in the blood as well as maintain high levels of the active steroids in the body.
Another way to combat this unwanted side effect is the use of Selective Estrogen Receptor Modulators, SERMs. These drugs are competitive partial agonists of the Estrogen receptors. They compete with Estrogen to bind to the Estrogen Receptor. Examples include Clomiphene and Tamoxifen. By binding to the Estrogen receptors, they reduce the action of Estrogen as it depends on binding to its receptor to exert its effects.
Steroids used for bulking cause hepatic injury. Milk Thistle has been shown to reduce the severity and as a result can be used on cycle to offer liver support.
A bulking cycle is therefore not complete with on cycle support as well as post cycle therapy.
