Dosage & Usage Guidelines
The standard dosage is 250–750 mg/week, administered via intramuscular injection. Due to its long half-life, 1–2 injections per week are sufficient. Beginners may start with 250–500 mg/week, while advanced users may combine with other compounds for enhanced effects.
Stacking Options
Testaplex C 250 is versatile and stacks well in bulking or cutting cycles. Popular stack combinations include:
- Decaplex 250 – for mass and joint support
- Methanoplex 20 – as a bulking kick-start
Estrogen Control and PCT
As an aromatizing compound, it may lead to water retention and gynecomastia. To manage estrogen, an AI like Letroplex can be used. Post-cycle, a proper PCT with Clomiplex or Tamoxifen is necessary to restore hormonal balance.
