Testobase is an injectable steroid produced by the pharmaceutical company Alpha Pharma. The main active ingredient is pure Testosterone (Testosterone Suspension) which is water-based and the most powerful form of the hormone. Since this form of the steroid has no ester attached to it, it starts to act immediately but its duration of action is also short. In bodybuilding, testosterone suspension preparations are often used by experienced steroid users who are looking for rapid results and don’t mind frequent injections.


Testosterone Suspension effects

  • Increase in lean muscle mass
  • Rapid increases in strength
  • Increased spermatogenesis and sexual behavior
  • Stimulation of erythropoiesis and distribution of subcutaneous fatty tissue
  • Influences nitrogen and phosphorus metabolism

Testosterone is popular with athletes for its ability to stimulate dramatic increases in muscle mass and strength. As a natural hormone, it remains the most popular anabolic steroid and is commonly used as the base for all cycles.


Usage information

Due to its short half-life, Testosterone Suspension needs daily injections. The cycle lasts no more than 5 weeks, and the daily dose is 20-100mg. Like other forms of testosterone, suspension is able to suppress endogenous testosterone secretion. To eliminate this reaction, it is recommended to combine the cycle with Gonadotropin. In this case, Gonadotropin should be taken 1000IU every week, in one injection.


Possible side effects

  • Increased blood pressure
  • Fluid accumulation
  • Masculinization
  • Aggression, irritability, agitation
  • Hair loss
  • Acne

In order to avoid side effects, we recommend taking blood tests and aromatase inhibitors (such as Anastrozole) during a Testosterone Suspension cycle and a SERM (Clomiphene or Toremifene) during post-cycle therapy (PCT).
