BRUTAL FORCE / FORMULA & TRAINING
Advertisement feature by Brutal Force. We benefit financially from sales of our top recommended products.
TestoPrime's name gives little away about its relevance to a training programme. The original blend contains D-aspartic acid, KSM-66 and several plant extracts. Our first choice remains Testogen Ultimate, while DBULK deserves a separate look when muscle building is the central aim.
Overall formula pick
Testogen Ultimate
Testogen Ultimate is the most convincing all-round choice here. TestoPrime has identifiable botanical differences; DBULK is the more relevant alternative to examine when the decision is about a muscle-focused supplement.

“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.
Capsule and other ingredients
Testogen Ultimate: Vegetable-cellulose capsule and NuFLOW rice-hull ingredient.
TestoPrime: Hypromellose, microcrystalline cellulose, silica, magnesium stearate and maltodextrin.
Do the training claims match the serving?
The KSM-66 extract amount in original TestoPrime is 55.68 mg. Do not compare a printed root-powder equivalent with the extract quantity used in a study. Testogen contains 200 mg of the same named extract, which is a meaningful formulation difference without being a prediction of a particular strength gain.
D-aspartic acid is almost equal between the two formulas. A 2,000 mg versus 2,025 mg comparison gives us no persuasive reason to expect different lifting outcomes. Research in resistance-trained men is a reason to keep expectations measured, whichever bottle you choose. 1
A broader daily formula wins our vote
The supporting nutrients explain our preference better than an argument about maximum doses. Testogen adds magnesium, boron, copper and K2 to its herbal selection. TestoPrime instead includes green tea, garlic and pomegranate, so it is a different design rather than simply an incomplete version of the same product.
TestoPrime supplies 40 mg zinc per daily serving. Include that when checking zinc from a multivitamin or other supplements. Testogen provides 25 mg zinc and 4,000 IU vitamin D3, which also need to be counted in your total intake.
The DBULK option for a muscle-building goal
On Brutal Force, we separate general testosterone support from a dedicated muscle-building goal. DBULK is our product for the latter: its leucine-and-botanical approach is different from TestoPrime's formula. Choose it because that approach fits your goal, not because a name implies drug-like gains or because adding another bottle must improve a stack.
- 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
