GP Test P100 is an injectable steroid containing the hormone Testosterone Propionate, available in concentrations of 100 mg per ML.
The Propionate ester acts much more rapidly (2-3 days) compared to Enanthate or Cypionate, necessitating a more frequent injection schedule, like daily or every other day, to maintain stable blood levels. However, the advantage of this is that GP Test P100 can be eliminated from the body much faster once use is stopped, making it a preferred option for athletes subject to testing. Additionally, some bodybuilders report that Propionate causes fewer estrogen-related side effects, such as bloating, compared to other esters of this potent hormone.
Testosterone is the most prevalent anabolic hormone and is considered the fundamental steroid. Because of this, bodybuilders often regard it as the foundational steroid for nearly all cycles. Testosterone possesses both anabolic and androgenic properties. Users will typically experience significant gains in muscle mass and strength, along with an enhanced sense of well-being and increased libido and sex drive.
Testosterone easily converts to estrogen, which can lead to estrogen build-up and related side effects for users who are sensitive to these issues or who are using high doses of this compound. Therefore, it is common for bodybuilders using Testosterone to include an anti-estrogen, such as Anastrozole, Proviron, or Tamoxifen, to minimize estrogen-related side effects. Users who are highly sensitive or taking very high doses (800-1200 mg) may find stronger anti-estrogens like Letrozole or Exemestane to be more appropriate. Androgenic side effects, such as oily skin, may also occur when taking Testosterone.
Bodybuilders aiming for bulk often combine GP Test P100 with other steroids like GP Deca 250 and/or GP Bold 200, along with an oral steroid like GP Methan or GP Oxy. Those bodybuilders wanting to incorporate testosterone during a cutting phase might stack it with compounds such as GP Trens, along with an oral like GP Stan or GP Oxan.
The use of testosterone will quickly suppress the body's natural hormone production, making a proper post cycle therapy (PCT) plan crucial for restoring natural functions and maintaining gains after steroid usage has stopped. At the end of a cycle, bodybuilders often opt for a combination of Clomid, Tamoxifen, and HCG for a duration of 3-4 weeks to swiftly and effectively restore the function of the pituitary gland and testes.
Female bodybuilders frequently utilize GP Test P100 for mass building, although the dosages are significantly lower than those used by males due to the risk of masculinizing side effects.
Typically, male bodybuilders will use GP Test P100 in the range of 400-1200 mg per week, with cycle lengths varying from 8 to 20 weeks, depending on the athlete’s objectives. Women generally see favorable outcomes from doses of 50-100 mg per week.
