Anyone have experience with either or both? Which is better?
I am pretty sure tribestan by Sopharma was the firstproduct to come out. Tribulus is supposed to increase LH and raise natural testosterone levels. Supplement companies now claim the component of trib. that is responsible for raising LH/ test is protodioscin. claims to have a higher concentration of protodioscin. The problem is there really haven't been any studies to support these claims. Sopharma did one or two. Their studies showed the trib. raised testosterone levels by 30% but also showed the it raised estrogen levels by close to 80 %. I tried tribestan by Sopharma when it first came out and I wasn't that impressed with it. I haven't tried the other brand but it looks like they are hoping people mistake it for the sopharma brand. Sopharma was the only company to put their trib. in a box, now ThermoLife is doing it.There is some debate if trib. even works at all.
The owner of ThermoLife used to work with the exclusive importer of Tribosten and went to Bulgaria many times to meet with them. When he started ThermoLife he developed a superior tribulus extract because the Bulgarians were so hard to deal with. ThermoLife did an independent lab test on the top selling tribulus products to prove they have the best product. They were the first ones to develop a high protodioscin extract. The Sopharma brand has always been around 9%-10% max. ThermoLife is guaranteed to be a minimum of 20%.Originally Posted by VanillaGorilla
