About the Product
Quamtrax Tribulus + ZMA is the most complete hormonal and nighttime recovery stack in the Quamtrax portfolio, combining in a single tablet Tribulus terrestris extract standardized to 90% saponins (the most concentrated natural testosterone booster available) with classic ZMA (Zinc + Magnesium + Vitamin B6) — the mineral triad for hormonal support, muscle recovery, and sleep quality. While Tribulus Plus standalone combines Tribulus + Zinc, Tribulus + ZMA also adds magnesium (in dual form: magnesium oxide + magnesium citrate) and Vitamin B6 as a cofactor for mineral absorption and protein metabolism. The Tribulus-ZMA synergy simultaneously covers the hormonal production axis (Tribulus via LH → testosterone), the mineral environment for testosterone synthesis (Zinc), muscle recovery and sleep (Magnesium), and protein metabolism (B6). 2 tablets/day. 90 tablets = 45 days of use. Vegan.
Ingredients: Tribulus terrestris dry extract (90% saponins, fruit) + Microcrystalline cellulose + Tricalcium phosphate + Guar gum + Magnesium oxide + Magnesium citrate + Magnesium salts of fatty acids + Zinc oxide + Pyridoxine hydrochloride (Vitamin B6).
Benefits
The Tribulus + ZMA synergy: the dual hormonal stack with four axes of action:
Quamtrax Tribulus + ZMA is superior to standalone Tribulus Plus (Tribulus + Zinc) and standalone ZMA (Zinc + Magnesium + B6) because it simultaneously covers the four axes of male hormonal support and sports recovery that neither of the other two covers individually. Tribulus (90% saponins) stimulates LH secretion and testosterone production. Zinc is a cofactor for testosterone synthesis and LH receptor function. Magnesium is essential for muscle relaxation, sleep quality (during which 70 to 80% of daily GH secretion occurs), and ATP synthesis. Vitamin B6 is a cofactor for amino acid metabolism, neurotransmitter synthesis, and improves intestinal absorption of zinc and magnesium. Together, the four components form the most complete hormonal support and nighttime recovery stack in a single dose.
Tribulus terrestris extract 90% saponins (fruit): the maximum concentration of protodioscin:
As already described in the sections on Tribulus Plus by Quamtrax and the previous Testo and Organic Tribulus in this session, Tribulus terrestris standardized to 90% saponins is the highest concentration available on the market — superior to the standalone Tribulus Plus from the same Quamtrax portfolio (also 90%, confirmed) and much superior to most products on the market (40 to 60%). The use of the fruit as part of the plant (vs. whole plant or aerial parts) ensures the highest content of protodioscin — the furostanic saponin with the highest documented hormonal activity — given that Tribulus terrestris fruit has a significantly higher protodioscin concentration than aerial parts. Protodioscin stimulates the release of LH by the anterior pituitary, which in turn stimulates the Leydig cells of the testes to produce testosterone.
ZMA: the reference mineral triad for recovery in sports nutrition:
ZMA (Zinc + Magnesium + Vitamin B6) is one of the most studied micronutrient combinations in sports nutrition for testosterone support, sleep quality, and muscle recovery. As already described in the sections on Marvelous Nutrition's ZMA, zinc and magnesium are the two most deficient minerals in intensively training athletes (lost in large quantities through sweat) and the two minerals with the greatest direct impact on the androgenic hormonal axis.
Zinc (zinc oxide): the direct cofactor for testosterone synthesis:
Zinc Oxide provides the elemental zinc necessary for the activity of 17β-HSD (the final enzyme in testosterone synthesis in Leydig cells) and for the maintenance of LH receptors on the membranes of Leydig cells. Zinc deficiency in athletes is directly associated with a reduction in serum testosterone. The study by Kilic et al. (2010) documented that zinc supplementation prevented the drop in testosterone induced by exhaustive exercise in wrestling athletes.
Magnesium (magnesium oxide + magnesium citrate): the dual form for maximum absorption and bioactivity:
The use of two forms of magnesium in Tribulus + ZMA is a smart formulation choice: magnesium oxide has the highest elemental magnesium content per gram (60%), being the most concentrated form to deliver large amounts of magnesium in a small tablet dose; magnesium citrate has higher oral bioavailability (citrate forms soluble complexes with Mg²⁺ that are absorbed more efficiently than oxide). The combination of the two forms balances concentration (oxide) with bioavailability (citrate), resulting in a magnesium intake that is both generous and efficiently absorbed. As already described in the section on Marvelous Nutrition's Magnesium Bisglycinate, magnesium is a cofactor for >300 enzymes, essential for muscle relaxation, ATP synthesis, and sleep quality (via modulation of GABA-A and NMDA receptors).
Vitamin B6 (Pyridoxine HCl): the cofactor that amplifies ZMA absorption and effect:
Vitamin B6 (pyridoxine hydrochloride) is included in ZMA for specific functional reasons: it is a cofactor for aminotransferases (amino acid metabolism, especially relevant for nighttime protein recovery), enzymes for neurotransmitter synthesis (serotonin, dopamine, GABA — modulators of sleep quality), and improves intestinal absorption and cellular utilization of zinc and magnesium. The combination of Zinc + Magnesium + B6 is more effective than zinc and magnesium alone because B6 amplifies the mineral effect at both the intestinal absorption level and the intracellular bioactivity level.
Pre-sleep use: the timing that maximizes Tribulus-ZMA synergy:
Quamtrax Tribulus + ZMA is ideal for taking before bedtime (following the classic ZMA protocol, which is typically taken 30 to 60 minutes before bed, on an empty stomach or away from calcium-rich foods). This timing is especially effective because: ZMA supports deep sleep quality (SWS — Slow Wave Sleep) during which 70 to 80% of daily GH secretion occurs; Tribulus supports the nighttime LH peak (which has a circadian rhythm peaking in the early hours of sleep); and magnesium directly promotes muscle relaxation and transition to sleep via GABAergic modulation. Quality sleep amplifies all hormonal and anabolic effects — without adequate sleep, no natural testosterone booster works to its full potential.
Uses
Recommended dose: Take 2 tablets daily with a glass of water. For maximum hormonal and recovery benefit, take 30 to 60 minutes before bedtime, away from calcium-rich foods (milk, cheese, yogurt) or calcium supplements (which compete with zinc and magnesium for intestinal transporters). Use in cycles: 8 weeks of use + 4 weeks off. 90 tablets = 45 days of use at 2 tablets/day.
