About the Product
Quamtrax Tribulus Plus is a supplement containing Tribulus terrestris extract standardized to 90% saponins combined with Zinc (100% of the Recommended Daily Allowance) in tablets, designed for male hormonal support, lean muscle mass development, and sexual health. With 385mg of Tribulus terrestris extract standardized to 90% saponins per tablet, Tribulus Plus offers one of the highest concentrations of Tribulus saponins on the supplement market — far superior to most products that use 40-60% saponin extracts. Zinc at 100% of the NRV enhances the hormonal effect of Tribulus as a direct co-factor in testosterone synthesis. 60 tablets. Free of doping substances.
Ingredients per tablet: Tribulus terrestris dry extract (90% saponins) 385mg + Zinc 10mg (100% NRV).
Benefits
Tribulus terrestris extract with 90% saponins: the highest standardization on the market:
The difference between a Tribulus extract with 40% saponins and one with 90% saponins is substantial — for the same extract dose (385mg), the 90% extract provides more than double the amount of biologically active saponins. This means that 385mg of Quamtrax extract (90% = ~346mg saponins/tablet) is equivalent in saponins to ~860mg of 40% extract (the typical value of many competitors). Protodioscin is the furostanic saponin from Tribulus terrestris with the most documented hormonal activity — it is the compound that preferentially stimulates the release of LH (Luteinizing Hormone) by the anterior pituitary, the hormonal step which in turn stimulates testosterone production by the Leydig cells of the testes. The concentration of protodioscin varies significantly depending on the part of the plant (the fruit has a higher concentration of protodioscin than the aerial parts) and the harvesting location (plants of Bulgarian and Macedonian origin historically have a higher protodioscin content than those of Indian or Chinese origin). An extract standardized to 90% total saponins guarantees a minimum of protodioscin per dose far superior to unstandardized or low-standardization extracts.
The Tribulus + Zinc synergy: the benchmark dual hormonal stack:
The combination of Tribulus terrestris (stimulator of LH and testosterone secretion via saponins/protodioscin) with Zinc (direct co-factor in testosterone synthesis in Leydig cells and LH receptor function) is the natural hormonal support combination with the strongest evidence base and most widely used on the market. Zinc is a co-factor of 17β-hydroxysteroid dehydrogenase (17β-HSD) — the enzyme that catalyzes the final step of testosterone biosynthesis (conversion of androstenedione to testosterone) — and is essential for maintaining LH receptors on the membranes of Leydig cells. Zinc deficiency is directly associated with hypogonadism and reduced serum testosterone in high-intensity athletes — and zinc replenishment normalizes testosterone levels in athletes with documented deficiency. The dose of 10mg of Zinc (100% NRV) per tablet fully covers the EU reference daily intake.
As already described in the Testo (Marvelous) and Organic Tribulus (Himalaya) sections: The protodioscin from Tribulus terrestris has a hormonal mechanism of action via LH, with documented effects on libido and sexual function, but with more moderate evidence regarding increased serum testosterone in healthy young men with normal testosterone. The effects are more pronounced in men with partial androgen deficiency, with low-normal testosterone, or in the context of intense physical stress (overtraining) that reduces testosterone levels.
90% saponins vs. Himalaya's Organic Tribulus (18% fruit saponins): the quality comparison:
Himalaya's Organic Tribulus uses fruit extract standardized to 18% saponins (250mg of extract = ~45mg fruit saponins, rich in protodioscin) + aerial parts powder with 1% saponins (438mg = ~4.4mg saponins). Quamtrax Tribulus Plus uses extract with 90% saponins (385mg of extract = ~346mg total saponins). In terms of total saponins per dose, Quamtrax Tribulus Plus has a significantly higher dose — although the specific protodioscin composition also depends on the botanical origin and the part of the plant used in the extract.
Free of doping substances: suitable for use in competitive sports:
Quamtrax Tribulus Plus is explicitly declared as free of doping substances — relevant for athletes competing under anti-doping regulations (WADA, NADO), given that male hormonal health supplements are subject to greater scrutiny for cross-contamination with prohormones or other prohibited compounds. Anti-doping certification ensures that the product has undergone specific tests for WADA-prohibited substances.
Development of lean muscle mass: the indirect mechanism via endogenous testosterone:
The effect of Tribulus on muscle development is indirect — by supporting endogenous testosterone levels (the main anabolic androgen) and supplementing with zinc (a co-factor in testosterone synthesis), Tribulus Plus can help maintain an optimal anabolic hormonal environment during intensive training cycles, especially when testosterone levels tend to decrease under chronic physical stress (overtraining). It is not a substitute for protein or creatine for muscle growth — it is hormonal support that optimizes endogenous conditions so that training and nutrition can produce the maximum anabolic effect.
Uses
Recommended dose: Check packaging for specific dose (typically 1 to 3 tablets/day with a meal). Use in cycles: 8 weeks of use + 4 weeks break to maintain hormonal receptor sensitivity. 60 tablets = 20 to 60 days of use depending on the dose. Free of doping substances — suitable for competitive athletes.
