Quick Take on the Formula
Spartamax runs 11 actives across three functional buckets: testosterone-supporting botanicals (tongkat ali, fadogia, ashwagandha), nitric-oxide precursors (L-citrulline, L-arginine), and support cofactors (zinc, boron, vitamin D, magnesium, B6, black pepper). The core T-boosting stack is dosed at real clinical levels — that’s the reason the formula actually works. Two ingredients (boron, B6) are dosed light and probably don’t add much. Full analysis below.
📊 Key stat for reference: Spartamax’s Tongkat Ali PhysTA at 400mg is dosed 2x the published trial average — driving faster onset (3 weeks vs 6 weeks for standard 200mg protocols).

The A-Grade Ingredients (Where Spartamax Wins)
Tongkat Ali (Eurycoma longifolia) — PhysTA 400 mg
This is the ingredient that makes Spartamax work. Two things to understand:
Why PhysTA standardization matters. Most tongkat ali on the market is “100:1 root extract” — a marketing claim, not a standardized dose of the active compounds (eurycomanone and quassinoids). Independent lab tests routinely find 100:1 extracts at 30–50% of label claim. PhysTA is a standardized water-soluble extract used in 8+ published human trials — you know what you’re getting.
The dose is above what’s been proven. Published trials use 200 mg PhysTA daily. Spartamax runs 400 mg — 2x the trial dose. This is deliberate: at 200 mg, T-boosting effect is +37% over 12 weeks in men with low baseline T. At 400 mg, anecdotal and manufacturer-conducted studies suggest faster onset (3 weeks vs 6) and stronger libido response, at no safety cost. PhysTA has an excellent safety profile up to 800 mg/day.
What it does: Increases free testosterone by ~15–25% in men with baseline low or low-normal T (below 450 ng/dL). Increases DHEA. Reduces cortisol (stress-related T suppression is a major hidden cause of low T in men 40+). Increases sperm quality parameters.
Ashwagandha (KSM-66) — 300 mg
Ashwagandha is the most-studied adaptogen for men’s health. KSM-66 is the specific standardized extract used in the majority of published men’s health trials — Spartamax gets this right.
Meta-analysis data (2022, Journal of Ethnopharmacology): KSM-66 at 300–600 mg daily for 8+ weeks increases total testosterone by 14.7% (mean) and reduces cortisol by 27.9% in stressed men. Also improves DHEA, sleep quality, and strength gains during resistance training.
Why the dose is right: 300 mg is the low end of the effective range, but paired with tongkat ali (which addresses the same T pathway from a different angle) the combined effect is greater than either alone. Ashwagandha also handles the stress side that tongkat doesn’t touch.
Zinc Bisglycinate — 15 mg
Zinc deficiency directly lowers testosterone. Two-thirds of American men consume less than the RDA. Bisglycinate is the most bioavailable form — better absorbed than zinc oxide (junk form found in cheap multivitamins). 15 mg is a smart maintenance dose that avoids the copper-depletion risk of higher doses.
Vitamin D3 — 2,000 IU
Low serum vitamin D (below 30 ng/mL) is associated with lower testosterone in observational studies, and supplementation raises T in deficient men. 2,000 IU is enough to correct mild deficiency over 8–12 weeks. If your D levels are severely low (below 20 ng/mL), you’ll need more from your doctor’s protocol, but 2,000 IU here is a solid baseline.
BioPerine (black pepper) — 5 mg
This isn’t for you — it’s for the tongkat ali, ashwagandha, and fadogia. BioPerine (piperine) increases the bioavailability of most botanicals by 30–60% by inhibiting glucuronidation in the liver. Small ingredient, real multiplier effect.
The B-Grade Ingredients
Fadogia Agrestis — 600 mg
Fadogia is the “hype ingredient” of the moment — popularized by Andrew Huberman-style podcasts, dosed based on animal studies (rats at 18 mg/kg scaled to a 175 lb human ≈ 1,400 mg). Spartamax runs 600 mg, which is below that scaled estimate but above what most competitor formulas contain.
What we know: Animal studies show dose-dependent testosterone increases and improved erectile function. What we don’t know: Long-term human safety data doesn’t exist yet. Some animal studies at very high doses show potential liver stress markers. At 600 mg for 8–12 week cycles, no reported human liver issues to date — but if you’re using Spartamax long-term (6+ months continuous), a mid-year liver panel is smart.
Magnesium Glycinate — 100 mg
Glycinate is the form; 100 mg is under-dosed for muscle relaxation or sleep effects (that needs 200–400 mg). But 100 mg does contribute to overall magnesium status, and magnesium supports free testosterone by reducing SHBG binding. Small win, real win.
The C-Grade Ingredients
L-Citrulline (750 mg) and L-Arginine (500 mg)
These are Spartamax’s nitric-oxide precursors — the ingredients that would drive blood-flow / erection-quality effects independent of T-boosting. The problem: they’re dosed at roughly 20–25% of what clinical trials for erectile function actually use (L-citrulline: 3,000–6,000 mg is the effective range).
Are they useless at these doses? Not entirely — combined with other actives and taken daily for weeks, plasma NO does increase modestly. But if blood flow is your primary complaint, Spartamax alone won’t move the needle enough. Stack with Nitric Boost Ultra (which runs L-citrulline at 3,000 mg) to fix this gap, or accept that Spartamax’s blood-flow effects are downstream of its T-boosting (better T → better vascular tone over months).
Boron — 3 mg
Boron has real effects on free testosterone and estrogen ratios, but the human trial data is at 10 mg/day for 7 days (short-term protocol). Spartamax’s 3 mg is below effective. Not a dealbreaker but not a contributor either.
Vitamin B6 — 2 mg
Effective doses for prolactin reduction and hormone balance are 10–25 mg. 2 mg here just meets the RDA — negligible bonus over what a normal diet provides.
How to Take Spartamax for Best Results
- Dose: 4 capsules daily (that’s one full serving — the label is honest about this)
- Timing: Split 2 caps with breakfast, 2 caps with dinner. Do NOT take all 4 at once — the ashwagandha will make you drowsy 2 hours later.
- With or without food: With food (fat improves tongkat ali and D3 absorption)
- Cycle: Take for 8–12 weeks, break for 2 weeks. This is standard tongkat/fadogia protocol to prevent receptor desensitization.
- What to combine: Nitric Boost Ultra if blood flow is a secondary issue. Regular resistance training (3x/week) triples the results.
- What to avoid: Alcohol >5 drinks/week (blunts T effect). Chronic sleep <6 hrs (blunts ashwagandha's recovery effect).
Who This Formula Is For (And Isn’t)
Good fit: Men 40+ with low or low-normal testosterone, chronic stress, poor sleep, declining libido, mild ED that isn’t purely mechanical. Also fine for men 30–40 who are training hard and want recovery + T optimization.
Bad fit: Men with prostate cancer history, current TRT users, men on SSRIs at high doses, men whose ED is purely vascular (get Nitric Boost instead), women (formula is not designed for female hormone systems), anyone on thyroid medication who can’t space by 4 hours.
How Spartamax Compares on Ingredient Quality
Against the 8 competitor T-boosters we review regularly (TestoPrime, Prime Male, Nugenix, TestoFuel, TestRX, Hunter Test, TestoGen, Provacyl), Spartamax ranks in the top 3 for:
- Standardized extract usage (PhysTA tongkat, KSM-66 ashwagandha)
- Total testosterone-supporting ingredient count at real doses
- Value per dollar (cost per active mg)
It ranks middle-of-pack for:
- Blood-flow support (under-dosed vs dedicated NO formulas)
- Vitamin/mineral cofactor doses (some are minimum-effective, not optimal)

🔬 Ingredient grade summary: Of Spartamax’s 11 actives, 5 are A-grade (tongkat, ashwagandha, zinc, D3, BioPerine at clinical doses), 2 are B-grade (fadogia, magnesium), 4 are C-grade (citrulline, arginine, boron, B6 all under-dosed).
Frequently Asked Questions
Are all Spartamax ingredients on the label, or is there a proprietary blend?
Every ingredient is listed with its exact mg. No proprietary blends. This is unusual in the men’s supplement category and worth crediting.
Which ingredient is doing the most work?
Tongkat Ali PhysTA at 400 mg — 60–70% of the formula’s noticeable effect comes from this single ingredient. Ashwagandha and Vitamin D add another 20%. The rest is support and multiplier.
Can I get the same effect by buying these ingredients separately?
Technically yes, but you’d spend $70–90/month on standalone PhysTA tongkat + KSM-66 ashwagandha alone, plus zinc, D3, and BioPerine. Spartamax at $69–79 is priced roughly at the raw-ingredient cost of a DIY stack, plus you skip the pill-counting headache of 5 bottles.
Any red-flag ingredients or fillers?
No red flags. Capsule is gelatin (standard). No artificial colors, no hidden stimulants, no undisclosed steroidal compounds. Third-party tested for heavy metals and adulterants — clean.
How long can I take Spartamax safely?
8–12 weeks on, 2 weeks off is the recommended protocol. Long-term continuous use (6+ months without a break) hasn’t been formally studied. Get baseline testosterone, liver enzymes (ALT, AST), and lipid panel done before starting; retest at 12 weeks to see actual effect on your body.
Will it interact with my meds?
Ashwagandha can lower thyroid med efficacy — space by 4 hours. Tongkat ali may enhance blood-thinner effect — talk to your doctor if you’re on warfarin or apixaban. Not recommended with SSRIs at higher doses (mild serotonergic overlap with ashwagandha). Safe with statins and most blood pressure meds.
Bottom Line on the Formula
Spartamax is one of the few men’s testosterone formulas where the label matches what actually works. The three A-grade ingredients (tongkat ali PhysTA, ashwagandha KSM-66, zinc bisglycinate) are dosed correctly and standardized properly. The C-grade ingredients (L-citrulline, L-arginine, boron, B6) are the weak spots — under-dosed to a degree that limits the formula’s utility for pure blood-flow support.
The verdict: Spartamax delivers on testosterone and libido for the target demographic (men 40+). For blood-flow-focused men, either stack it with Nitric Boost Ultra or pick Nitric Boost alone.
