Introducing OSL Turkesterone

'Turkesterone supplement bottle with red and white label featuring 'Old School' logo.'

What is it?

Turkesterone is a naturally occurring ecdysteroid, a type of steroid hormone found in plants and insects.

What does it do?

Turkesterone increases muscle mass by promoting protein synthesis, essential for muscle repair and growth. It enhances endurance and strength, making it popular among athletes and bodybuilders. As an adaptogen, it helps the body cope with stress, improving health and recovery. Unlike anabolic steroids, turkesterone is non-hormonal and doesn’t interfere with natural hormone levels, reducing side effects. It also aids in fat loss by boosting metabolism and promoting fat breakdown.

Why OldSchoolLabs?

Although Turkesterone is a good supplement by itself, we have taken the extra step of adding a rare and potent herbal supplement called Tongkat Ali. This truly sets us apart, giving you the maximum of the maximum. Additionally, our labels are completely transparent, so you know exactly what you are putting in your body, unlike other brands that sell products with “special blends.”

Adaptogen Properties:

As an adaptogen, turkesterone can help the body cope with stress, which is beneficial for overall health and recovery from intense physical activity.

Non-Hormonal:

Unlike anabolic steroids, turkesterone is non-hormonal and does not interfere with the body's natural hormone levels, reducing the risk of side effects associated with steroid use.
