Testolent
Active Substance: Testolent
Description
Testolent is the brand name for the anabolic-androgenic steroid (AAS) Testosterone Phenylpropionate (TPP).
It is an injectable form of testosterone where the testosterone hormone is modified with a phenylpropionate ester to prolong its release after injection.
Different Names:
-
Testosterone Phenylpropionate (TPP)
-
Testosterone phenpropionate
-
Testosterone hydrocinnamate
It is also notably an ingredient in some mixed-ester testosterone products like Sustanon and Omnadren.
Benefits and Side Effects (Based on Testosterone and its Esters)
Since Testolent is a form of testosterone, its benefits and side effects are similar to other testosterone preparations, especially when used for purposes like hormone replacement therapy (TRT) or bodybuilding.
Pros and Cons (In the context of other Testosterone Esters)
Testosterone Phenylpropionate has a moderate release rate, placing it between the fast-acting Testosterone Propionate and the long-acting Testosterone Enanthate/Cypionate.
Dosage and Frequency
There is no widespread modern medical standard for Testolent (TPP) alone, but information can be inferred from its past use and its role in blended products.
-
Clinical/Historical (Single Ester): When available as a standalone product (Testolent), its duration of action was approximately 8 days. This suggested an injection frequency of around once per week for maintaining relatively stable therapeutic levels.
-
Blended Products (e.g., Sustanon): In mixes, the TPP component contributes to the mid-duration release. Sustanon 250 (which contains 60 mg TPP) is often administered every 3 to 4 weeks in a clinical setting, relying on the longer esters for sustained levels.
-
Bodybuilding/Performance: Performance-enhancing dosages are highly variable and generally fall outside medical recommendations. Due to its half-life, users often inject 200-400 milligrams or more, divided into injections once or twice per week to keep levels stable. Note: These dosages are associated with higher health risks.
Pharmacokinetics
Sterogenic, Progestronic, Prolactin Effects
-
Sterogenic Effects (Aromatization): As a testosterone ester, Testolent is readily aromatized (converted) by the body's aromatase enzyme into estradiol (estrogen). This is its primary "sterogenic" (estrogenic) effect and is the source of side effects like gynecomastia and water retention.
-
Progestronic Effects: Testosterone and its esters are generally considered to have negligible or no direct progestogenic activity (i.e., they do not directly bind strongly to the progesterone receptor).
-
Prolactin Effects: Testosterone and its derivatives do not typically cause a direct increase in prolactin. However, very high estrogen levels resulting from the aromatization of high-dose testosterone can sometimes indirectly influence prolactin levels, as estrogen is known to increase prolactin production. Significant elevations in prolactin are more commonly associated with certain other classes of steroids (like Trenbolone or Nandrolone) or specific medical conditions.
Anabolic-Androgenic Ratio
Testosterone and all its esters, including Testolent (Testosterone Phenylpropionate), are the benchmark for this ratio.
-
Anabolic:Androgenic Ratio = 100:100
In the simplified numeric format requested: 100:100 (or simply 1:1).
