Buy Sustaplex 350 – Axiolabs Sustanon Blend (350 mg/mL)
Sustaplex 350 by Axiolabs is a high-concentration blend of four testosterone esters, formulated to deliver both rapid and sustained anabolic action. Each 1 mL contains 350 mg of combined testosterone from the following esters:
- 42 mg Testosterone Propionate
- 84 mg Testosterone Phenylpropionate
- 84 mg Testosterone Isocaproate
- 140 mg Testosterone Decanoate
This combination mimics the traditional Sustanon concept but with an increased dosage, offering faster results and extended activity — ideal for serious mass-building cycles.
Why Choose Sustaplex 350?
Sustaplex 350 is designed to provide both immediate elevation of testosterone and prolonged anabolic effects. It's an excellent option for athletes who want strong performance results with less frequent injections than short-ester testosterone requires.
Benefits of Sustaplex 350
- Fast-acting yet long-lasting testosterone support
- Rapid gains in size, strength, and endurance
- Elevated libido and recovery rates
- Fewer injections due to blend efficiency
Dosage and Administration
Recommended dosage is 350–700 mg per week, administered in 1–2 injections weekly. Higher doses may be used by experienced athletes depending on cycle structure.
Stacking Suggestions
Sustaplex 350 is highly versatile and stacks well with orals and injectables. Popular combinations include:
- Decaplex 250 – for enhanced bulking synergy
- Methanoplex 20 – for a rapid strength and mass kickstart
Estrogen Control and PCT
Due to aromatization, users may require AI support such as Letroplex. Following the cycle, proper post cycle therapy with Clomiplex or Tamoxifen is necessary to restore endogenous testosterone production.
