BRUTAL FORCE / FORMULA & TRAINING
Advertisement feature by Brutal Force. We benefit financially from sales of our top recommended products.
If Nugenix has caught your attention because of strength or physique goals, start with its actual formula. This review covers the original product, not Total-T, T2 or Ultimate. Testogen Ultimate is our leading testosterone-support recommendation; DBULK addresses a more specifically muscle-focused purchase.

“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.
Nugenix: Other-ingredient list not verified for this version.
A blend total is not a workout dose
Citrulline malate appears in original Nugenix, but its individual quantity sits inside a 2,103 mg complex with Testofen and tribulus. That leaves no sound basis for treating this bottle as a measured citrulline supplement for training. An ingredient name and an assessable dose are different pieces of information.
The same issue applies to Testofen. We can recognise the named extract without claiming the blend matches a published study. Tribulus also does not turn the whole combination into a proven testosterone intervention for trained men. 1 2
Why our testosterone pick is Testogen
Testogen's four-capsule serving sets out its ingredients separately, including 2,025 mg D-aspartic acid and 200 mg KSM-66. That makes a more useful starting point for a ingredient-based purchase than guessing how a proprietary complex is divided. It does not establish a guaranteed increase in strength.
For us, the distinction is a broad, specified daily formula rather than an acute pre-workout effect. The vitamin and mineral forms, transparent quantities and short other-ingredient list support that choice. A harder session after starting a product is not, by itself, evidence that testosterone has risen.
The DBULK option for a muscle-building goal
DBULK belongs in this decision if the original shopping goal was muscle building rather than a general testosterone formula. Its mix includes L-leucine, ashwagandha and MSM. We would assess that training-oriented combination separately, instead of pretending it is a like-for-like replacement for Nugenix's Testofen blend or a reason to take two products together.
- Muscle-oriented formula with L-leucine, ashwagandha and MSM.
- Also described with puncture vine, sodium hyaluronate, suma and vitamin D3.
- Three capsules daily on the product page; follow the directions on the supplied bottle.

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. 3
Unwanted reactions warrant stopping the product and obtaining appropriate advice. Ongoing symptoms need proper assessment; this comparison cannot diagnose testosterone deficiency or replace treatment. 4
