What is Tribulus terrestris?
Tribulus terrestris is a plant used in herbal supplements, often marketed for libido and testosterone. Those are different outcomes: a change in a sexual-function questionnaire does not demonstrate increased testosterone, muscle growth or faster workout recovery.
What does the research support?
In a five-week trial in 22 male rugby players, 450 mg daily of a tribulus extract did not add to strength or fat-free-mass gains from training. That result does not prove every possible formulation is ineffective, but it argues against treating tribulus as an established muscle-building supplement.
A 2017 trial in 180 men with erectile dysfunction found improved sexual-function scores with Tribestan versus placebo. It used 1,500 mg daily of a specific extract for 12 weeks. The result concerns that preparation and population; it does not establish hormone correction or benefits for healthy athletes.
How much is in Bucked Up RUT?
The current manufacturer description of RUT Testosterone Booster lists 750 mg tribulus extract standardized to 95% saponins per three-capsule serving. A percentage of total saponins is not proof of equivalence to the particular furostanol-saponin preparation used in the sexual-function trial.
RUT also contains ashwagandha, tongkat ali, DIM, vitamin D, folate and zinc. Ingredient research cannot establish what this combination will do. No controlled finished-RUT trial was identified in the sources reviewed here.
What about the spray?
The His deer-antler spray lists tribulus within a 1,000 mg proprietary mixture. Its individual dose is undisclosed, so it cannot be compared with RUT’s 750 mg. Combining them would add an unknown amount of tribulus and other ingredients without an established extra benefit.
Check the whole formula for safety
RUT supplies 125 mcg (5,000 IU) vitamin D per serving, above the general adult upper limit of 100 mcg. Get clinician guidance before routine use, especially with other vitamin D products. Its 30 mg zinc also counts toward total daily intake. A tribulus-focused purchase should not overlook these other ingredients.
Medication use, endocrine symptoms or a medical condition deserve professional review. Persistently low energy or sexual difficulties are not enough to diagnose low testosterone. Drug-tested athletes should also consider the separate anti-doping risks of deer-antler products.

Bottom line: Limited sexual-function findings should not be converted into a promise of higher testosterone, better recovery or greater strength.
