Start with the facts
A clear guide to original Tribestan
Tribestan.org separates three things that are often mixed together online: current product information, the broader subject of Bulgarian Tribulus terrestris, and documented historical research material.
Follow the Bulgarian development story
Read the documented history of the product and the work led by Assoc. Prof. Margarita Tomova, Pharm.D.
Explore the research library
Browse documented studies, charts and comparative materials while keeping historical sources separate from current instructions.

Documented Bulgarian history
More than a product name
A Sopharma historical document describes Tribestan as an original phytochemical product developed from Tribulus terrestris L. growing in Bulgaria. It identifies a long research process led by Margarita Tomova and states that she worked for more than 20 years on the creation of the product.
Assoc. Prof. Margarita Tomova, Pharm.D. is therefore not a decorative historical reference. Her work is central to the documented development story behind Tribestan.

Why specification matters
Not every Tribulus product is equivalent
Tribulus terrestris is a botanical name, not a guarantee that two finished products are identical. When comparing products, check the plant material, extraction method, declared amount per tablet or capsule, standardized compounds, manufacturer and accompanying documentation.
Useful questions before buying
- Who manufactures the finished product?
- How much extract is present in one tablet or capsule?
- Which compounds are standardized and how are they described?
- Is the package clearly identified and supplied with a leaflet?
- Is the seller transparent about the product origin?
