Sustanon 300

Sustanon 300, by Valkyrie Pharmaceutical, is a known brand-name of the popular testosterone formula, particularly among bodybuilders and athletes. Each testosterone ingredient differs in its ester, and subsequent rate of release into the body for a sustained peaked release during its lifespan of 32 days. As a result, this boosts mass and strength in a sustained and potent way. Most users take between 250 to 2000 milligrams through weekly injections. Although, its benefits come with some side effects that should be considered.

What It Is And How It Works:

Sustanon 300 formula is a mixture of different testosterone products, most of which can be acquired on their own. The basic chemical build of these ingredients is the same across them, the attached delivery agent controlling its metabolism speed is different. With different peaking times of the ingredients is supposed to deliver a sustained maximal effect of the drug with a lower injection frequency.

While some formulas ingredient list is not always true to form, the Valkyrie brand of Sustanon is well-known for its quality and can help many buyers feel reassured of the ingredients contained within it.

The different testosterone forms in the mix include:

  • Testosterone propionate (60 milligrams): half-life of 4 to 5 days
  • Testosterone phenylpropionate, (70 milligrams): half-life of 4 to 5 days
  • Testosterone isocaproate, (70 milligrams): half-life of 8 to 10 days
  • Testosterone decanoate (100 milligrams):  half-life of 9 days

Administration And Use

As an oil-based solution, Sustanon injection is administered via intramuscular injection. This is done once weekly to keep levels, and subsequent benefits, at their highest levels. Popular points for such injection include the buttock, due to the gluteal muscles locating there, and the side of the shoulder where the lateral head of the deltoid muscle is. These sites are usually switched up for added comfort and hygiene during administration.


Doses can vary for athletes, as more experienced users of anabolics adapt to their use with greater androgen receptor quantity in the body. Gender also plays a big role in the sensitivity to anabolic effects. As such, this means a general guide needs to be revised, as seen below:


  • Beginners - 250 to 500 milligrams, administered once weekly
  • Intermediates - 500 milligrams, administered once every 5 to 7 days 
  • Advanced - 1000 to 2000 milligrams, administered once weekly 
  • Females are advised to avoid its use completely, due to androgen-related side effects like virilization 

Side effects 

There are two main types of adverse events associated with the use of Sustanon 30: direct effects, caused by the testosterone itself, and indirect effects caused by the concurrent processing and its metabolites. Both of these are listed below:

Direct side effects 

These include:

  1. Drop, or complete stop, in the amount of endogenous testosterone produced
  2. Larger heart size, and higher LDL cholesterol, plus blood vessel stiffness increase
  3. Hepatic strain with use, which can cause liver damage if continued for excessive periods

Indirect side effects

These include:

  1. High estrogen in the body, which raises water retention and fat gain, as well as boosting blood pressure
  2. Increased Dihydrotestosterone, causing androgen-mediated problems like oily skin and acne, and hair loss faster in people predisposed to hair loss, and a virilizing impact on females
