Testolab-P 100 by 7Lab Pharma – Fast-Acting Testosterone Propionate for Lean Muscle Growth

Brand: 7Lab Pharma, Switzerland

Substance: Testosterone Propionate

Action of the Drug

Testolab-P 100 is a fast-acting testosterone ester that promotes muscle growth, strength, faster recovery, and improved performance. Its short half-life ensures quick results, precise hormonal control, and minimal water retention—perfect for lean cycles and strength-focused athletes.

Use in Sports

Widely used in bodybuilding, powerlifting, and fitness for mass gain, cutting, and recomposition phases. Its clean anabolic profile helps athletes gain dense muscle while keeping fat levels low.

Period of Drug Withdrawal

Testosterone Propionate clears the system within 7-10 days after the last injection, making it easy to plan post-cycle therapy (PCT) without delay.

Rate of Suppression of Natural Testosterone Production

As with all testosterone esters, Testolab-P 100 significantly suppresses natural testosterone. Proper PCT is essential to restore endogenous production post-cycle.

What Should Be Used During and After Use

During use:

• Aromatase inhibitors (Arimidex, Aromasin) to manage estrogen
• Regular blood work to monitor hormone levels

After use:

• Clomid or Nolvadex for PCT
• Natural testosterone boosters (DAA, Zinc)
• Liver support if combined with orals

Combinations with Other Anabolic and Androgenic Drugs

Testolab-P 100 stacks effectively with:

• Masteron or Winstrol for cutting cycles
• Trenbolone Acetate for recomposition
• Anavar or Primobolan for lean muscle gains
• Equipoise or NPP for mild bulking phases

Possible Side Effects and How to Avoid Them

• Estrogenic effects (bloating, gynecomastia) – controlled with AIs
• Androgenic effects (acne, aggression) – dose-dependent
• Injection frequency – requires every-other-day injections for stable blood levels
• Testosterone suppression – always follow with a full PCT

Why We Recommend It

As a coaching team, we recommend Testolab-P 100 for athletes seeking rapid results, precise hormonal control, and minimal water retention. Ideal for short cycles, cutting, or kick-starting longer cycles with faster gains than slower esters.

Comparison with Other Drugs

Compared to Testosterone Enanthate or Cypionate, Propionate works faster, causes less water retention, and clears the body quicker—perfect for athletes preparing for competitions or short, effective cycles. Requires more frequent injections but delivers cleaner results.
