Letro-Lab by 7Lab Pharma, Switzerland – Potent Letrozole Aromatase Inhibitor

Brand: 7Lab Pharma, Switzerland

Substance: Letrozole

Action of the Drug

Letro-Lab contains Letrozole, a powerful aromatase inhibitor that effectively reduces estrogen levels, helping to prevent estrogen-related side effects during anabolic steroid cycles.

Use in Sports

Athletes use Letro-Lab to control estrogen buildup, avoid water retention, and reduce the risk of gynecomastia, especially when running aromatizable steroids like testosterone or trenbolone.

Period of Drug Withdrawal

Letrozole has a moderate half-life, and a withdrawal period of 1-2 weeks is typically sufficient before starting post-cycle therapy (PCT).

Rate of Suppression of Natural Testosterone Production

Letrozole itself does not suppress natural testosterone but supports hormonal balance by lowering estrogen, aiding recovery during and after cycles.

What Should Be Used During and After Use

During use: Liver support supplements and cardiovascular protectors.
After use: PCT drugs such as Clomiphene Citrate (Clomid) and Tamoxifen (Nolvadex) to stimulate testosterone recovery.

Combinations with Other Anabolic and Androgenic Drugs

Common combinations include:
- Testosterone (Propionate, Enanthate) to prevent estrogen-related side effects
- Trenbolone to avoid gynecomastia
- Boldenone or Dianabol cycles where estrogen control is critical

Possible Side Effects and How to Avoid Them

• Joint pain or stiffness – maintain hydration and consider fish oil supplements
• Potential negative impact on cholesterol – monitor lipid profiles and maintain a healthy diet
• Excessive estrogen suppression – use the lowest effective dose to avoid joint and mood issues

Proper dosing and cycle monitoring minimize side effects.

Why We Recommend It

Letro-Lab is highly recommended for athletes needing effective estrogen control, ensuring cleaner cycles with reduced water retention and improved muscle definition.

Comparison with Other Drugs

Compared to other aromatase inhibitors like Anastrozole, Letrozole offers stronger estrogen suppression but requires careful dose management to avoid over-suppression.
