Stealth Labs Testosterone Cypionate 250 is a pharmaceutical-grade injectable anabolic steroid designed for testosterone replacement therapy (TRT) and muscle-building cycles. Each 10 mL vial contains 250 mg/mL of pure Testosterone Cypionate, offering athletes and TRT users a slow and steady hormonal release profile with fewer injections per week.
Testosterone Cypionate is one of the most popular long-acting esters due to its smooth onset and extended active life of up to 10 days. This makes it a preferred compound for both beginner and advanced steroid users looking to build size, strength, and improve overall well-being during bulking phases.
Most users administer 250–500 mg weekly. Injections are typically split into 1–2 doses per week for more stable serum testosterone levels. Advanced users may increase to 750 mg/week, though this raises the risk of estrogenic and androgenic side effects.
Stealth Labs Testosterone Cypionate pairs well with other compounds for synergistic results. For bulking cycles, stack with Stealth Deca Durabolin 300 or Stealth Anadrol 50. For cutting, a mild stack with Stealth Winstrol 50 helps retain lean mass.

Testosterone Cypionate can convert to estrogen via aromatization, which may lead to water retention, gynecomastia, or increased blood pressure. To mitigate this, users may incorporate Stealth Arimidex 2 mg or another aromatase inhibitor (AI) into their cycle.
To restore natural testosterone production, begin PCT 2–3 weeks after your last injection. Effective options include Clomid or Nolvadex over a 4-week protocol. Using HCG during cycle may also help prevent testicular atrophy and facilitate smoother recovery.
In clinical settings, Testosterone Cypionate is used to treat hypogonadism in men. According to medical literature on testosterone therapy, it remains one of the most effective long-acting androgens for stable hormone replacement.

Most users begin noticing improvements in strength, libido, and energy within 2–4 weeks, with visible muscle gains following by week 5 or 6.
Due to its strong androgenic nature, it is not recommended for female use unless under specific medical guidance, as it may cause virilization.
Yes, Testosterone Cypionate is commonly prescribed for TRT due to its stable blood level profile and long duration between injections.
