BRUTAL FORCE / FORMULA & TRAINING
Advertisement feature by Brutal Force. We benefit financially from sales of our top recommended products.
Prime Male and TestoPrime share enough ingredient names to look interchangeable, but the servings tell another story. We would choose Prime Male of the pair when KSM-66 is the priority. Testogen remains our overall testosterone-support pick, with DBULK for a dedicated muscle-oriented choice.
Overall formula pick
Testogen Ultimate
We favour Prime Male for the pair's KSM-66 comparison, Testogen for the overall daily formula, and DBULK for a specifically muscle-building goal.

“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.
Prime Male: Prime Male Vitality. All 12 manufacturer-identified active ingredients are shown. Unverified quantities and the conflicting black-pepper unit are marked explicitly. This assessed formula uses Panax ginseng; older mucuna-containing versions are not mixed into it.
Capsule and other ingredients
Testogen Ultimate: Vegetable-cellulose capsule and NuFLOW rice-hull ingredient.
Prime Male: 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.
Extract identity makes this comparison possible
Both products identify KSM-66, so their actual extract amounts can be compared: 300 mg in Prime Male and 55.68 mg in original TestoPrime. This does not prove a proportional performance difference. It does prevent a powder-equivalent headline from obscuring the amount being taken.
Neither figure gives a licence to apply every ashwagandha training result to the finished blend. The research regimen and whole product would still need to match. Testogen's 200 mg is also a formulation entry rather than a guaranteed strength outcome.
Choose the supporting formula deliberately
Prime Male offers magnesium and nettle; TestoPrime has green tea, garlic and pomegranate. Both are four-capsule routines. A lifter should therefore decide whether the ingredient selection fits rather than assuming either brand has a capsule-count advantage.
Testogen combines KSM-66 and D-aspartic acid with a wider selection of specified nutrients. That overall formulation earns our recommendation. Prime Male provides more KSM-66, as shown in the full comparison.
The DBULK option for a muscle-building goal
For a muscle-building purchase, DBULK is the Brutal Force product we would examine after settling the distinction between general support and training-specific intent. Its leucine-and-MSM-containing blend is a separate design, not an extra layer that must be added to either Prime Male or TestoPrime.
- 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. 1
