BRUTAL FORCE / FORMULA & TRAINING
Advertisement feature by Brutal Force. We benefit financially from sales of our top recommended products.
For an active reader comparing Nugenix with TestoPrime, the first question is whether each ingredient dose can actually be assessed. TestoPrime has the advantage there. Testogen is our leading overall recommendation, and DBULK offers the distinct muscle-focused route.
Overall formula pick
Testogen Ultimate
TestoPrime wins the pair on assessability; Testogen wins our overall formula choice. DBULK is the alternative for a muscle-building rather than general testosterone-support 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.
TestoPrime: Hypromellose, microcrystalline cellulose, silica, magnesium stearate and maltodextrin.
TestoPrime
original 12-ingredient TestoPrime, not TestoPrime Gold; 4 capsules.
Citrulline on a label does not make a pre-workout
Original Nugenix includes citrulline malate but does not disclose its share of the 2,103 mg complex. You cannot assume the bottle supplies a particular training-oriented citrulline dose. The shared blend also prevents a precise Testofen dose comparison.
TestoPrime's individually stated ingredients avoid that uncertainty. Its D-aspartic acid and KSM-66 still need realistic expectations: ingredient disclosure helps assessment, but is not proof that the finished formula improves gym performance. 1
A clearer label is the beginning of the decision
We would favour TestoPrime over original Nugenix for formula visibility and variety. We then prefer Testogen for its 200 mg KSM-66 and broader nutrient selection, including magnesium and boron alongside its other herbs.
Nugenix's methylcobalamin B12 remains a distinguishing nutrient that Testogen omits. Our recommendation is not an attempt to make every ingredient identical. It reflects which complete daily-support design we find more persuasive for general testosterone support.
The DBULK option for a muscle-building goal
DBULK provides a more specifically muscle-oriented option than either side of this named comparison. Its leucine, ashwagandha and MSM selection should be judged for that purpose. If that was the goal all along, choosing the appropriate category is more useful than expecting an unspecified blend to behave like a targeted workout product.
- 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. 2
