What is Supertest 450?
Supertest 450 is a mega mix of several testosterone esters at very high total concentration (450mg/ml). Essentially it is a souped-up Sustanon with even more different esters and higher concentration. But the compound remains testosterone.
Anabolic steroid, not a peptide, ready to use.
How it works
All esters release testosterone, which binds the androgen receptor and drives muscle growth, strength and male hormone effects. The variety of esters only smooths the release curve, the high concentration reduces the injection volume. Pharmacologically it is simply high-dose testosterone.
Use
Intramuscular (glute, thigh), ready to use. The very high concentration means a small volume is enough.
- Inject with a clean IM needle, disinfect the injection site.
- Rotate injection sites.
- Subcutaneous: a multi-ester blend with short esters and a high solvent load irritates subQ strongly - IM clearly preferred.

What the research shows
As with the other test mixes: testosterone as hormone replacement is established, the high mega-mix dosing is not. High-dose performance use is not covered by controlled studies, and risk scales with the dose (pharmacology context: Yarrow, 2010).
Side effects
- Like testosterone generally, but more pronounced due to the high dose.
- Estrogen effects, axis suppression, lipid shift, blood pressure.
- High doses clearly strain the heart and circulation.
Practice
- High concentration means: dose precisely, no crude syringe errors.
- Watch bloodwork, plan a post-cycle.
- Banned in official competition (WADA S1).
Storage
Store at room temperature, cool and protected from light, out of reach of children. Keep the original bottle closed and mind the expiry date.
