Description

Product Overview

Sustanon 250 mg/ml by Alpha BioPharma is a unique testosterone blend containing four different esters designed to provide both fast-acting and long-lasting testosterone release. This formulation ensures a rapid rise in testosterone levels after injection, followed by a sustained release over several weeks.

Favored for both testosterone replacement therapy (TRT) and performance cycles, Sustanon 250 combines convenience with steady hormone support, strength gains, and muscle growth. Its multi-ester design reduces injection frequency compared to short esters, while still offering a quicker onset than very long esters.

Composition

Each 1 ml injectable solution contains:

• Testosterone Blend (Sustanon) – 250 mg

  • Testosterone Propionate

  • Testosterone Phenylpropionate

  • Testosterone Isocaproate

  • Testosterone Decanoate

• Benzyl Alcohol (BA) – 2.0% (preservative)

• Benzyl Benzoate (BB) – 23.0% (solvent/stabilizer)

• MCT Oil – q.s. to 1 ml (carrier oil)

Formulated with pharma-grade MCT oil to ensure smooth injections and consistent absorption.

Pharmacological Profile

• Class: Anabolic-Androgenic Steroid (AAS)

• Ester Mix: Propionate, Phenylpropionate, Isocaproate, Decanoate

• Half-life: Mixed profile → rapid onset (24–48h) with long-lasting release (up to 2–3 weeks)

• Anabolic Effects: Protein synthesis, muscle growth, increased bone density

• Androgenic Effects: Development of male sexual characteristics (voice deepening, body hair growth)

• Erythropoietic Effect: Stimulates red blood cell production → improves oxygen transport and endurance

• Aromatization: Yes (may convert to estrogen → risk of gynecomastia, water retention)

Benefits & Effects

• Multi-Ester Stability: Delivers both fast and long-lasting testosterone release

• Steady Hormone Levels: Less fluctuation compared to single-ester formulations

• Endurance & Energy: Boosts red blood cell count for training intensity

• Convenience: Reduced injection frequency compared to Propionate alone

Recommended Dosage & Use

• TRT (Hypogonadism): 50–250 mg every 2–4 weeks (individualized to bloodwork)
