Sp Propionate 1 bottle/10 ml (100 mg/1 ml)


Sp Propionate (Testosterone Propionate) from Sp Labs is mainly used during the drying cycle. However, it also works well during weight gain cycles. During the drying cycle, the athlete must reduce the amount of calories consumed. A strict diet is followed to give the body what it needs and reduce the remaining fat.

With the help of propionate, it is easier to maintain the desired level of testosterone in the body than with other testosterone esters. That's why larger ester bases are often bypassed and used instead.

Advantages of the drug for medical purposes: it is often used for men who do not naturally produce enough testosterone. This can lead to physical and mental symptoms. As testosterone levels increase, these symptoms can be reduced or eliminated.

Steroid profile of propionate

  • anabolic activity – 100% of testosterone,
  • androgenic activity – 100% of testosterone (high),
  • aromatization (conversion to estrogens) – high (there is a need for anti-estrogens),
  • suppression of the hypothalamus-pituitary-testis axis – expressed,
  • method of administration – injections,
  • duration of action – 2-3 days,
  • elimination period and mrt (in/m) – 0.8 days and 1.5 days, respectively,
  • the peak of propionate activity occurs on the day of injection and gradually decreases during 2436 hours after injection,
  • detection time – 40-60 days.

Effects of taking propionate

The drug has a short duration of action. Injections are usually given every other day. This is one of the main disadvantages of using propionate, in comparison with its more long-lived analogues, for example, with Enanthate.

  • increases muscle mass,
  • increases the level of igf-1 and mgf hormones,
  • reduces the amount of fat in the body,
  • reduces the risk of heart ischemia and coronary disease,
  • increases libido and potency (possible reverse effect),
  • increases strength
  • improves muscle relief,
  • increases energy
  • accelerates regeneration,
  • increases collagen synthesis,
  • increases the content of minerals in bone tissue,
  • anti-catabolic effect on muscle tissues due to its action as an anti-glucocorticoid,
  • if the dosage is chosen correctly, it is possible to avoid water retention or minimize this effect.
  • Application and dosage of propionate

    It may be the only steroid on the course, but the best effect is achieved when combined with other drugs. Athletes starting to use anabolic agents can be recommended dosages of 50 mg of propionate every other day. The usual dose of more experienced athletes is 100 mg of propionate daily and above.

    Be sure to take anti-estrogen drugs, for example, Proviron or aromatase inhibitors according to the standard scheme, starting from the second week to avoid the development of gynecomastia, fluid retention and other estrogenic effects. After the end of the introduction, post-course therapy is carried out, most often tamoxifen is used. It is also desirable to take cortisol blockers to preserve the gained weight. Be sure to follow a weight gain diet and take sports nutrition.

    Combined course

    When dry, it combines well with stanozolol, trenbolone acetate, masteron, primobolan and some other drugs. Propionate is included in the mixture of testosterone esters such as sustanon or omnadren, as a mandatory component that allows you to immediately feel the work of the steroid.

    An example of a cycle for novice "chemists" for propionate-based drying:

    • Propionate 50 mg every other day
    • Winstrol 30 mg per day, starting with 10 mg, and bringing the dose to the optimum within 1 week.
    • After 6 weeks, anabolic agents should be canceled and PCT should be started after 3-4 days.

    Side effects

    This is a good choice for healthy men. When used by someone with low testosterone, there are rarely any side effects. However, at higher doses, for example, to increase productivity, there is a higher risk of side effects:

    • gynecomastia,
    • acne,
    • baldness of the scalp,
    • hirsutism (body hair),
    • prostate enlargement (especially in the elderly),
    • masculinization (in women).

    Some people have a genetic link to possible side effects or other health problems.
