TESTOGEN · FORMULA COMPARISON
Standard Nugenix T-Booster and Mars Men use different approaches to ingredient disclosure. Mars Men’s current panel states the quantities of its principal actives individually. Standard Nugenix combines three ingredients in a 2,103 mg complex. This article concerns standard Nugenix, not Total-T.

OUR VERDICT
Our recommendation
Mars Men provides more individual dose information than standard Nugenix’s central blend. Our overall pick is Testogen Ultimate, which also declares its active amounts and adds the broader nutrient and botanical combination we prefer.

What the Nugenix blend does and does not tell you
The standard Nugenix complex contains citrulline malate, Testofen fenugreek and tribulus. Its 2,103 mg total is useful information, but it does not tell you the amount of each. We therefore cannot fairly compare Nugenix’s fenugreek dose numerically with Mars Men or Testogen.
Testofen is still an identifiable branded extract, and its specification deserves to remain visible. A blend limitation does not erase that strength or establish that an ingredient is underdosed.

Amounts apply to each stated serving. Extract weights, raw-herb equivalents and elemental nutrient amounts are different measurements.

“Not included” means absent from the assessed formula. “Not verified” means the available information does not establish the detail; it does not imply the brand hides it. Blend totals and their ingredients must not be added together twice.
Testogen Ultimate: 13 active ingredients. Mineral figures are nutrient amounts, not the weight of the full mineral compound.
Mars Men: Current 11-active label assessed 11 September 2026. It lists taurine 750 mg; accompanying website text says 675 mg. This table follows the panel. Older Mars Men formulations differ.
Nugenix: Standard Nugenix T-Booster. The 2,103 mg complex is the combined weight of citrulline malate, Testofen and tribulus, not the amount of each ingredient.
Capsule and other ingredients
Testogen Ultimate: Vegetable-cellulose capsule and NuFLOW rice-hull ingredient.
Mars Men: Vegetarian capsules stated; full other-ingredient list not shown on the assessed panel. Dicalcium phosphate appears in the K2 preparation.
Nugenix: Gelatin capsule and magnesium stearate.
Mars Men offers a different set of choices
Mars Men has tongkat ali, shilajit, cistanche and taurine, plus separate nutrients. It does not provide the citrulline-and-tribulus selection of standard Nugenix. Comparing only the zinc row would miss most of the actual decision.
Testogen offers another route: disclosed KSM-66, standardized fenugreek and Panax ginseng, nettle root and D-aspartic acid, accompanied by specified nutrients. We favour this combination while leaving the competitor-only ingredients in the full table.
Why Testogen gets our recommendation
Individual quantities make it easier to compare the formula and identify overlap with other supplements. Testogen pairs that transparency with magnesium, P5P B6, D3, MK-7 K2, zinc, copper and boron. Standard Nugenix lists B6, B12 and zinc, and Mars Men lacks several of Testogen’s listed nutrients.
The recommendation is for Testogen’s overall selection, not a claim that every person needs more nutrients. Someone committed to Testofen or to Mars Men’s specific botanicals has a different reason to choose. The table keeps those reasons visible.
Evidence and sensible expectations
The tables compare composition, not proven head-to-head outcomes. A named extract can help identify what is being studied, but an ingredient study does not automatically validate a finished multi-ingredient product. For example, KSM-66 has been studied at 300 mg twice daily in a resistance-training trial; Testogen’s 200 mg serving is different. 2
D-aspartic acid research also includes mixed findings. We do not promise that adding it, or choosing the longest formula, will produce a particular testosterone increase. Our recommendation reflects the combination and ingredient detail we prefer. 3
Check suitability before combining supplements
Testogen supplies 100 mcg (4,000 IU) vitamin D3 daily, at the commonly used adult upper intake level. Count other sources; this is not a target everyone should aim to reach. 1
Do not stack these formulas simply because their ingredients differ. Check nutrient overlap, medicines and health conditions with an appropriate professional. Persistent fatigue or changes in sexual health deserve assessment rather than an assumption that a supplement will resolve them.
Questions before choosing
Does this compare the current Mars Men formula?
Yes. It follows the current 11-active label, including 750 mg taurine. The accompanying website text differs on taurine; older versions should not be mixed into this comparison.
Why include Testogen in this comparison?
Mars Men provides more individual dose information than standard Nugenix’s central blend. Our overall pick is Testogen Ultimate, which also declares its active amounts and adds the broader nutrient and botanical combination we prefer.
Should I take these products together?
No combined regimen is recommended here. Choose according to suitability and avoid duplicating nutrients or botanicals without appropriate advice.
Our final choice
Mars Men makes more individual dose information available than standard Nugenix’s central blend. Testogen Ultimate pairs that same kind of dose clarity with the nutrient and botanical selection we prefer, making it our overall recommendation.

Unknown details remain marked rather than treated as absent. Ingredient forms, extract weights and raw-herb equivalents are kept distinct.
