Testosterones Family

Details on the Testosterones Substance Family

  • Class: Anabolic Steroid
  • Structure: Testosterone
  • Aromatization: Yes
  • How to take: Injectable (though there are also oral and transdermal options, injectable Test is the most common and most effective form)
  • Primary use: Flexible (can be used for TRT, bulking, cutting, as a base for many steroid cycles)
  • Compounds in the family: 8 (esters, blends and solutions).


Testosterone is the Alpha and Omega of the steroid world. The basis for most compounds, the starting point for all the designer steroids. Your body produces Testosterone as an anabolic-androgenic agent, the primary male sex hormone, on its own in Leydig cells. However, you can improve the levels with injectable solutions.

Testosterone itself is the basis for most steroidal compounds that alter its effect. We have the most popular, tried-and-true options available:

  • Testosterone Enanthate (half-life of 10,5 days);
  • Testosterone Cypionate (half-life of 11 days);
  • Testosterone Propionate (half-life of about 4,5 days);
  • Testosterone Decanoate (slow, TRT-optimized ester);
  • Testosterone Suspension (extremely short half-life of 3-4 hours);
  • Pre-made blends (different esters and steroids combined in one vial for optimized effect).

Testosterone History & Development Timeline

Testosterone is a natural substance, but we’re talking about the synthetic version of it. The original Test was around, of course, since the first caveman grew a beard and lifted some heavy stone. The synthetic version, though it’s 1:1 identical, has a shorter history:


  • 1920s: Scientists start getting curious about the male hormone. What makes a man a man?
  • 1935: Boom! Testosterone is isolated. In 1937 it became commercially available. Medical professionals start using it to treat all sorts conditions, from low libido to depression;
  • 1940s-50s: Testosterone therapy becomes more popular. Think more than just low T levels: Test plays a vital role in the treatment of menopause, aging, and even some cancers;
  • 1950s: Bodybuilders start injecting the early versions of Testosterone. Enanthate and Cypionate esters make it to the market;
  • 1960s-70s: The early Golden Era of bodybuilding. Arnold and the gang are on the scene. Testosterone and other anabolics become the not-so-secret sauce for massive gains;
  • 1970s: The FDA starts clamping down. Testosterone gets classified as a controlled substance;
  • 1980s: The cat’s out of the bag. Everyone knows about steroids in bodybuilding. Controversies start, and so do bans in competitions;
  • 1990s-2000s: Testosterone Replacement Therapy (TRT) becomes an extremely popular thing;
  • 2020s: Testosterone is still widely used, but now it’s not just about getting jacked, it’s about doing it smart. PCT becomes a thing, aromatization is a well-known term. In general, today’s Testosterone cycles are safer than ever.

Testosterone Esters & Blends Comparison

Testosterone Enanthate

Think of this as the most reliable and basic version of Testosterone. With a half-life around 10 days, it’s a slow burner, giving you a steady release. It’s one of the most common forms of Testosterone used, especially for TRT.

Testosterone Cypionate

This is like Enanthate’s cousin who lives a state over. Almost identical, with a half-life just a smidge longer at about 11 days. It’s another slow and steady option, often interchangeable with Enanthate in many treatments. It’s just less popular.

Testosterone Propionate

Here’s your faster version. With a half-life of roughly 4 days, it’s the ester you need for bulking. It gets into your system quickly but also means you’ll be doing injections more often.

Testosterone Decanoate

This ester is optimized for long, smooth rides. It’s designed with TRT in mind, ensuring those on the therapy get a consistent and prolonged dose with no daily injections. TRT often lasts for years (if not for life), so constant pinning would be a pain in the… injection site. That’s why the slowest ester works best for it.

Testosterone Suspension

The drag racer of the class. No ester tail means it has no chemical constraints that would slow down the release, just water and alcohol. With a half-life of just a few hours, it’s in and out of your system. Perfect for those who want a rapid Testosterone boost. You need to pin it multiple times a day and time it perfectly with your workouts to get the most out of it.

Pre-made Blends

These are your custom options, tailored for specific needs. Products like Test-400, Cut-Mix, or Sustanon combine different esters and even other steroids to give users an optimized effect. It’s like having a whole cycle mixed in the same vial (perfectly OK chemistry-wise, also — quite effective).
