BRUTAL FORCE / FORMULA & TRAINING
Advertisement feature by Brutal Force. We benefit financially from sales of our top recommended products.
Ageless Male and Nugenix share Testofen, but a training-focused reader needs more than a shared ingredient name. We favour Ageless Male for the disclosed amount within this pair. Testogen leads overall, and DBULK is the option we feature for a muscle-building goal.
Overall formula pick
Testogen Ultimate
For the named Testofen decision, we favour Ageless Male. For broad support, Testogen is our pick; for the muscle-building goal, consider DBULK.

Ageless Male
original Testofen-based Ageless Male shown on the reviewed label, not Ageless Male Max; 2 tablets; 38 servings per container.

“Not included” indicates confirmed absence from the assessed formula. “Not verified” identifies a gap in the information available for this comparison; it does not mean the manufacturer hides the amount.
Testogen Ultimate: 13 active ingredients. Mineral figures are nutrient amounts, not the weight of the full mineral compound.
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.
Ageless Male: Microcrystalline cellulose, rice flour, croscarmellose sodium, magnesium stearate, hypromellose, glycerin and hydroxypropyl cellulose.
Nugenix: Other-ingredient list not verified for this version.
Nugenix
original standard US Nugenix, not Total-T, T2 or Ultimate; 3 capsules.
The Testofen comparison is clear enough to be useful
Ageless Male states 600 mg Testofen, while original Nugenix does not disclose its share of the three-ingredient complex. That makes the Ageless Male serving easier to relate to named-extract research. It does not establish a comparative muscle-gain result. 1
Nugenix includes citrulline malate and tribulus, but their separate amounts are also undisclosed. The formula should not be assumed to provide a particular workout dose of citrulline simply because the ingredient appears on the label.
What changes when Testogen enters the choice
Testogen provides a different fenugreek extract and a substantially broader herb-and-nutrient combination. Its KSM-66, D-aspartic acid and specified mineral forms are the basis of our recommendation. They are not a claim that Testogen has matched Ageless Male's Testofen dose.
Original Ageless Male remains a focused four-active product with clearly specified nutrient forms. The preference for Testogen is about choosing the more extensive overall design, not dismissing the usefulness of a simpler formula for someone who wants that extract.
The DBULK option for a muscle-building goal
DBULK is the muscle-oriented Brutal Force alternative for readers whose goal is not really a Testofen comparison. Its leucine-and-botanical mix should be assessed for that separate purpose. The most useful next step is to decide which role you need, rather than combine products because their advertising emphasises different benefits.
- Muscle-oriented formula with L-leucine, ashwagandha and MSM.
- Also described with puncture vine, sodium hyaluronate, suma and vitamin D3.

Review overlapping vitamins, minerals and herbs before adding a product to an existing training stack. Testogen contains 4,000 IU (100 mcg) D3, so its dose needs to be considered with other sources. A preferred formula is not automatically suitable for every user. 2
Unwanted reactions warrant stopping the product and obtaining appropriate advice. Ongoing symptoms need proper assessment; this comparison cannot diagnose testosterone deficiency or replace treatment. 3
