What is Testosterone Cypionate?
Testosterone Cypionate (Test C) is a long-ester testosterone widely used in bodybuilding, hormone replacement therapy, and performance enhancement. Due to its slow release, it allows for stable testosterone levels with less frequent injections, making it a popular choice among athletes.

Usage Guidelines

• Typical performance range: 300–600 mg per week
• Advanced users: 600–1,000 mg per week (short-term use)
• Injection frequency: Once or twice weekly due to its long half-life
Administration: Injectable form only, as oral use is ineffective due to poor bioavailability
Stacking: Commonly used as the base of bulking or cutting cycles; pairs well with Deca Durabolin, Dianabol, Trenbolone, or Winstrol
Aromatase Inhibitors: Consider using anastrozole or letrozole to control estrogenic side effects
Post Cycle Therapy: SERMs like clomifene or toremifene are recommended to restore natural testosterone production
