Sports bodies that follow the World Anti-Doping Code ban them in and out of competition. This is general information, not legal advice.

Thank you for the five stars! Halotestin is one of the harsher orals, so keep it short and check your liver and lipids.

This is what I'm taking about ! Love it ! Strong and hard as long as you eat healthy. The product is proper.

Thank you! You're right that diet makes all the difference. Halotestin is one of the harsher orals on the liver and cholesterol, so keep it short and keep an eye on your bloodwork.
