Sustaplex 275 is an injectable steroid that consists of the hormone testosterone in five distinct esters, totaling 275 mg. Each milliliter of Sustaplex 275 contains the following:
Testosterone Propionate - 30 mg,
Testosterone Phenylpropionate - 75 mg
Testosterone Isocaproate - 70 mg,
Testosterone Decanoate - 100 mg
These esters have varying release times in the bloodstream, contributing to stable hormone levels with regular injections. Bodybuilders typically opt for a dosing schedule of three times a week (for example, Sunday, Tuesday, Thursday) when using Sustaplex 275.
Testosterone is recognized as the most prevalent anabolic hormone and is also viewed as the foundational steroid for nearly all cycles. It possesses both anabolic and androgenic properties. Users of this steroid can expect significant muscle size and strength increases, alongside an improved sense of well-being and heightened libido.
Testosterone has a high tendency to aromatize, leading to potential estrogen buildup and related side effects for those susceptible to such issues or those taking high doses. Consequently, bodybuilders frequently use anti-estrogens like Anastrozole, Proviron, or Tamoxifen to mitigate estrogen-related side effects. Users who are particularly sensitive or who utilize very high doses (800-1200 mg) may find that stronger anti-estrogens like Letrozole or Exemestane are more appropriate. Additionally, androgenic side effects, such as oily skin, may occur during Testosterone use.
The usage of Testosterone will quickly suppress the body’s natural hormone production, making a proper post-cycle therapy (PCT) plan crucial for restoring natural function and preserving gains post-steroid use. At the end of a cycle, bodybuilders often opt for a combination of Clomid, Tamoxifen, and HCG for 3-4 weeks to effectively and rapidly restore the functioning of the pituitary gland and testes.
Female bodybuilders sometimes use testosterone to increase mass, although the dosage is considerably lower than that used by men due to the risk of masculinizing side effects.
The typical dosage for male bodybuilders using Sustaplex 275 ranges from 400-1200 mg per week, and the cycle duration may last from 8 to 20 weeks, depending on the athlete's objectives. Women generally achieve desirable results from doses of 50-100 mg per week.
