Sustanon 250 mg (Testosterone Blend) – 1 ml Ampoule

Sustanon 250 mg is a premier, oil-based injectable solution for Testosterone Replacement Therapy (TRT). Manufactured by Aspen, this 1 ml ampoule is renowned for its unique blend of four different testosterone esters, designed to provide a phased, long-lasting release of the hormone.

It is a prescription medication for men with clinically diagnosed low testosterone levels (male hypogonadism).

Product Overview: Sustanon 250 mg (Testosterone Blend)

Sustanon 250 mg is one of the most well-known names in testosterone therapy. Its innovative formula sets it apart from single-ester testosterones (like Enanthate or Cypionate). It is specifically engineered to provide both a rapid onset and a sustained duration of effect from a single injection.

This 250 mg blend is composed of:

• Testosterone Propionate (30 mg)
• Testosterone Phenylpropionate (60 mg)
• Testosterone Isocaproate (60 mg)
• Testosterone Decanoate (100 mg)

This blend is intended to restore normal testosterone levels, alleviating symptoms of hypogonadism such as low libido, fatigue, depression, and loss of muscle mass.

How Does Sustanon 250 mg Work?

The four testosterone esters in Sustanon 250 have different “half-lives,” which means they are released into the bloodstream at different speeds.

1. Fast-Acting (Propionate & Phenylpropionate): These short esters provide a quick release of testosterone within the first 24-48 hours, rapidly raising blood levels and alleviating symptoms sooner.
2. Long-Acting (Isocaproate & Decanoate): These longer esters are released slowly over weeks. They provide the stable, long-term “tail” of the therapy, maintaining testosterone levels for an extended period.

The goal of this blend is to create a more stable and “even” testosterone level, reducing the “peaks and troughs” that can be associated with some single-ester injections.

Key Product Details

Dosage and Administration

Sustanon 250 mg is a prescription-only medication that must be administered by a healthcare professional (e.g., a doctor or nurse).

• Route: Deep intramuscular (IM) injection.
• Frequency: The clinical dosing for TRT is highly individualized. A common standard protocol is one 250 mg (1 ml) injection every 3 weeks.
• Your doctor will determine the exact injection interval based on your testosterone blood levels.

Important: Your doctor will monitor your blood levels (total testosterone, hematocrit, PSA) to ensure your dose is correct and to manage potential side effects.

Frequently Asked Questions (FAQ) about Sustanon 250 mg

How is Sustanon 250 different from Testosterone Enanthate?

Testosterone Enanthate contains only one ester (Enanthate). Sustanon 250 contains four esters. Sustanon was designed to act faster (due to the Propionate) and last just as long (due to the Decanoate), all from a single shot. However, many modern TRT protocols favor single esters for their more predictable release kinetics.

Is Sustanon 250 an anabolic steroid?

Sustanon 250 is bioidentical testosterone. Its only approved medical use is to treat low testosterone (TRT). Because of its powerful anabolic (muscle-building) properties, it is widely misused and abused in the bodybuilding community. This off-label use is illegal in many places and carries serious health risks.

How often is Sustanon 250 injected?

For its medical purpose (TRT), it is typically injected by a doctor once every 2 to 3 weeks. Off-label (non-medical) users often inject it more frequently, which is not a medically approved protocol.

What are the common side effects of Sustanon 250?

Side effects are the same as any testosterone therapy. This includes potential conversion to estrogen, leading to water retention or gynecomastia. It can also cause acne, oily skin, and polycythemia (an increase in red blood cell count), which must be monitored by a doctor.

Important Safety Information

Warning: Testosterone therapy carries risks and is not suitable for everyone.

Do not use Sustanon 250 if you:

• Have or are suspected to have prostate cancer.
• Have or are suspected to have male breast cancer.
• Are allergic to any of the four esters or to peanut oil (which is sometimes used as a carrier).

This medication is for male use only and must not be used by women, especially those who are pregnant or breastfeeding, as it can cause severe virilization and fetal harm.
