Sustalab-250 by 7Lab Pharma – Advanced Testosterone Blend for Steady Gains

Brand: 7Lab Pharma, Switzerland

Substance: Testosterone Decanoate, Testosterone Phenylpropionate, Testosterone Propionate, Testosterone Isocaproate

Action of the Drug

Sustalab-250 is a multi-ester testosterone blend designed for both immediate and sustained release of testosterone into the bloodstream. It delivers steady anabolic effects, enhancing muscle mass, strength, recovery, and overall performance throughout the cycle.

Use in Sports

Popular among bodybuilders, powerlifters, and strength athletes, Sustalab-250 is used for both bulking and recomposition. Its stable blood levels make it a versatile choice for long-term cycles without frequent injections.

Period of Drug Withdrawal

The combination of short and long esters means full clearance occurs within 3–4 weeks after the last injection, so PCT should be planned accordingly.

Rate of Suppression of Natural Testosterone Production

Strong suppression of endogenous testosterone production occurs, requiring a well-structured PCT for hormonal recovery.

What Should Be Used During and After Use

During use:

• Aromatase inhibitors (Arimidex, Aromasin) to control estrogen
• Regular blood work to monitor hormone balance

After use:

• Clomid or Nolvadex for PCT
• Natural testosterone boosters (DAA, Zinc, Vitamin D3)

Combinations with Other Anabolic and Androgenic Drugs

Sustalab-250 stacks effectively with:

• Dianabol or Anadrol for mass gain
• Trenbolone for strength and recomposition
• Equipoise or Deca-Durabolin for size and endurance
• Winstrol or Masteron for cutting

Possible Side Effects and How to Avoid Them

• Estrogenic effects (bloating, gynecomastia) – use AIs
• Androgenic effects (acne, oily skin) – dose management
• Increased hematocrit – monitor with blood tests
• Testosterone suppression – follow with complete PCT

Why We Recommend It

Our coaching team recommends Sustalab-250 for athletes seeking long-lasting testosterone release with fewer injections and consistent performance benefits throughout the cycle.

Comparison with Other Drugs

Compared to single-ester testosterones like Enanthate or Cypionate, Sustalab-250 offers a more balanced release profile, reducing hormone fluctuations and injection frequency.
