What is Testosterone Propionate (TP)?
Testosterone Propionate is perhaps the most important ester of synthetic testosterone ever produced. It was introduced in the early 1930’s and was the first testosterone ester to be marketed in the medical field. It was the primary form of testosterone used until longer-acting esters were introduced in the 1960’s. TP has the shortest ester, allowing for user-controlled release of the hormone into the body. Optimal blood plasma levels can be obtained in a matter of hours, which can be extremely advantageous to bodybuilders looking to gain lean muscle mass and strength. By maintaining a frequent injection schedule, stable and peaked blood-hormone levels can be obtained due the short half-life of the ester. Although TP most similarly resembles the naturally occurring male androgen testosterone, it does not provide a sustained release of the hormone, and therefore, is rarely used for TRT due to the frequent injection schedule.
The same benefits can be obtained with TP as with all other testosterone esters, including: increased metabolic rate, red blood cell count, and IGF-1 output, enhanced protein synthesis and nitrogen retention, increased recovery and endurance, and fat-loss benefits. The anabolic/androgenic rating is 100/100.
What is the recommended dosage?
The recommended dosage of TP varies widely depending on who you talk to. In our opinion, a sensible dosage for most athletes is between 300-1000mg per week. It is recommended to maintain a daily dosage schedule in order to sustain peaked hormone levels, however, 3-4 times per week is acceptable.
A typical cycle will last 8-12 weeks, with a maximum of 20 weeks at higher dosages.
What does TP stack well with?
Testosterone Propionate may be added to any stack due to its considerable benefits. It stacks well with other quick-acting injectables such as Mastering Propionate, NPP, Trenbolone Acetate, or Deca Durabolin. Oral steroids such as Winstrol and Anavar also stack well with Testosterone Propionate. It is highly recommended to use an estrogen blocker/aromatase inhibitor with all testosterone varieties.
