Formula snapshot
What is Tribulus Terrestris?
Tribulus terrestris is supplied here as a concentrated 10:1 extract. The extract weight and botanical equivalent describe different things: the amount you receive and the source material represented.
A declared extract ratio makes the concentration clear.
Each 465mg capsule represents a 4,650mg botanical equivalent using the 10:1 ratio. The ratio describes source-material concentration; it is not a measured saponin percentage.

Great
I’ve been taking these Tribulus Terrestris capsules for a few weeks and notice a real difference in my workouts. The extract feels potent yet gentle on my stomach, and I appreciate that it comes from organic sources without fillers. I feel stronger and more energised, and the clean capsules fit nicely into my supplement routine.
They definitely work
Tribulus went in during a heavier gym month. I’ve felt a bit more driven in sessions, not a huge kick but enough to notice
Tribulus has been in my gym bag for a few weeks. sessions feel a bit more focused and the capsules don’t feel harsh
tribulus is subtle for me, but workouts feel a bit more consistent. I’m not chasing a buzz, just something steady
Great product like everything crown supplements does.
