Magnus Sustanone 10ml/250mg Testosterone Blend
Product Overview
- Brand: Magnus

- Volume: 10 mL vial containing 250 mg of total testosterone esters
- Ester Composition:

How It Works
The blend of four distinct testosterone esters provides a rapid rise in plasma testosterone levels within 24–48 hours post‑injection, followed by a sustained release that maintains physiological concentrations for roughly 21 days. This dual‑phase action allows users to experience both immediate anabolic effects and prolonged support with fewer injections compared to single‑ester preparations.
Administration Guidelines
- Typical Dosage: 250–750 mg per injection, depending on experience level and training goals.
- Injection Frequency: Every 7–10 days for bulking cycles; can be adjusted to a 3–4 week schedule in clinical settings.
- Cycle Length: Commonly 6–12 weeks of active use followed by a post‑cycle recovery period.
- Injection Site: Intramuscular (e.g., gluteal, deltoid). Use sterile technique and appropriate needle length.
Side Effects & Considerations
- Aromatization: Testosterone converts to estradiol; may cause water retention, fat gain, and gynecomastia if estrogen levels rise significantly.
- Androgenic Effects: Oily skin, acne, increased body/facial hair growth, and potential acceleration of male pattern baldness in genetically predisposed individuals.
- Lipid Profile Impact: Possible reduction in HDL cholesterol and elevation of LDL cholesterol, increasing cardiovascular risk if not monitored.
- Other Risks: Liver strain is minimal due to injectable form; however, regular blood work for liver enzymes, lipid panels, and hormone levels is recommended.
