Primal Storm Ingredients: All 6, and What the Research Says
Primal Storm's 838 mg Proprietary Male Support Blend holds six herbs, listed heaviest first: tribulus, horny goat weed, longjack (tongkat ali), Panax ginseng, ashwagandha, and yohimbe last, meaning smallest by weight. The label never breaks out a single milligram amount. This page walks through all six, checks each against its own research dose, and gives yohimbe the extra attention its risk profile calls for.
What's actually inside Primal Storm's 838 mg blend?
Six herbs share one number. Weight order shows who leads; it does not show the dose.

Equal bars are a placeholder, not a claim. The label lists 6 ingredients in one 838 mg total and does not say how much of each is inside.
One serving is 2 capsules, and every pair carries the same 838 mg blend. US labeling rules require blend ingredients to print heaviest to lightest, so tribulus sits first and yohimbe sits last. That order is the only quantity clue on the label; the milligrams themselves stay hidden inside the combined total. Here is the label order:
- Tribulus Terrestris Extract
- Horny Goat Weed Extract
- Longjack Extract
- Ginseng Root Extract
- Ashwagandha Extract
- Yohimbe Extract

Tribulus Terrestris Extract
Tribulus terrestris · plant
Listed first, which on a blend means the largest share by weight. A 2025 systematic review found Tribulus improved erectile function in some trials at 400-750 mg/day but had little consistent effect on testosterone.
- In one serving
- Inside the 838 mg blend (amount not published)
- Dose used in research
- 400-750 mg/day of standardized extract for 1-3 months in the reviewed trials
- Safety note
- LiverTox rates Tribulus terrestris an unlikely cause of liver injury at typical doses, and the one severe case (jaundice and kidney dysfunction in a bodybuilder) was judged more likely caused by undisclosed anabolic steroid use rather than Tribulus itself.

- Vilar et al., 2025
Horny Goat Weed Extract
Epimedium sagittatum · herb
A traditional Chinese herb; its research is mostly in animals. No controlled human efficacy trials of Epimedium or icariin for sexual function were found; erectile benefits are shown only in rat studies.
- In one serving
- Inside the 838 mg blend (amount not published)
- Dose used in research
- no established human efficacy dose
- Safety note
- LiverTox rates horny goat weed an unlikely cause of liver injury, but a 2025 case report documented severe muscle spasms and markedly elevated creatine kinase and creatinine in a man who took an unregulated online Epimedium supplement.

Longjack Extract
Eurycoma longifolia (tongkat ali) · root
Also called tongkat ali. The best-studied men's root in the blend. Multiple small RCTs and a meta-analysis show testosterone increases, especially in men with low baseline levels or age-related androgen deficiency; trial durations are mostly short (2 weeks to 6 months).
- In one serving
- Inside the 838 mg blend (amount not published)
- Dose used in research
- 200-600 mg/day standardized root extract
- Safety note
- Tongkat Ali is generally well tolerated in short clinical trials with no consistent liver-enzyme changes, but LiverTox rates it a possible, rare cause of liver injury based on one case report that was confounded by concurrent bodybuilding and possible undisclosed steroid use.
Ginseng Root Extract
Panax ginseng · root
Asian ginseng, studied for fatigue and for erectile function. Systematic reviews describe the evidence for fatigue and erectile function as modest or suggestive but not conclusive, due to small and lower-quality trials.
- In one serving
- Inside the 838 mg blend (amount not published)
- Dose used in research
- roughly 600 mg-3 g/day of standardized ginseng extract, often taken for several weeks
- Safety note
- Asian/Panax ginseng may lower blood sugar levels, so people on diabetes medication should use it cautiously.

Ashwagandha Extract
Withania somnifera · root
An Ayurvedic herb studied for stress and, in one trial, men's hormones. A single placebo-controlled crossover RCT in aging, overweight men found 600 mg/day of ashwagandha extract raised testosterone and DHEA-S versus placebo, though self-reported vitality and sexual well-being improved equally in both groups.
- In one serving
- Inside the 838 mg blend (amount not published)
- Dose used in research
- 600 mg/day of standardized extract
- Safety note
- NIH ODS reports a small number of serious adverse-event cases linked to ashwagandha, including liver injury (jaundice, elevated bilirubin) in people taking 450-1,350 mg/day that resolved after stopping use, and thyrotoxicosis in three women that also resolved after discontinuation, consistent with ashwagandha's reported ability to raise thyroxine (T4) levels.

Yohimbe Extract
Pausinystalia yohimbe · bark
A bark extract linked to serious side effects, including high blood pressure and fast heart rate. A 1998 meta-analysis of 7 RCTs found purified yohimbine outperformed placebo for erectile dysfunction, but that evidence predates modern PDE5-inhibitor drugs and used a pharmaceutical-grade, known dose -- not an undisclosed botanical extract inside a proprietary blend.
- In one serving
- Inside the 838 mg blend (amount not published)
- Dose used in research
- older RCTs of purified yohimbine for erectile dysfunction used roughly 15-30 mg/day of yohimbine hydrochloride
- Safety note
- Yohimbe/yohimbine carries the most serious safety profile in this blend: NCCIH links it to cardiac arrhythmia, blood pressure problems, heart attacks, and seizures, and a poison-control analysis found yohimbe callers needed medical care more often than other supplement callers.

Primal Storm's dose vs. the research dose, ingredient by ingredient
| Ingredient (label order, heaviest first) | Amount in Primal Storm | Dose used in research | Human evidence |
|---|---|---|---|
| Tribulus Terrestris Extract | Not published | 400-750 mg/day of standardized extract for 1-3 months in the reviewed trials | Limited |
| Horny Goat Weed Extract | Not published | no established human efficacy dose | Weak |
| Longjack Extract | Not published | 200-600 mg/day standardized root extract | Moderate |
| Ginseng Root Extract | Not published | roughly 600 mg-3 g/day of standardized ginseng extract, often taken for several weeks | Limited |
| Ashwagandha Extract | Not published | 600 mg/day of standardized extract | Limited |
| Yohimbe Extract | Not published | older RCTs of purified yohimbine for erectile dysfunction used roughly 15-30 mg/day of yohimbine hydrochloride | Limited |
Tongkat ali alone was studied at 200-600 mg a day, tribulus at 400-750 mg, ashwagandha at 600 mg. Stack any two of those and you are already past 838 mg, before ginseng, horny goat weed or yohimbe get any share at all. Something here sits under its studied dose.
The math gets harder still with yohimbe in the mix, since its safe range and its active range sit close together. More: how Primal Storm works.
The three roots: tribulus, horny goat weed and longjack
Three of the six ingredients are roots or root extracts with a long history in men's formulas: tribulus, horny goat weed and longjack. They lead the blend by weight, in that order.
Tribulus terrestris is first on the label, so it is the largest single share of the 838 mg. A 2025 systematic review found tribulus, at 400-750 mg a day for one to three months, improved erectile function in three of five studies, mostly in men with mild to moderate erectile dysfunction, but eight of ten studies found no meaningful change in testosterone (Vilar et al., 2025).
Horny goat weed is second by weight. Its main compound, icariin, helped nerve-injured rats regain erectile response in lab studies, but no human trial has tested it for sexual function (Shindel et al., 2010). A safety trial found icariin tolerated up to 840 mg a day but causing GI upset at 1,680 mg, with poor absorption throughout (Brown et al., 2019).
Longjack is the label's name for Eurycoma longifolia, better known as tongkat ali, the best-studied root here. A meta-analysis found it raises testosterone, especially in men with low starting levels, at roughly 100-600 mg a day (Leisegang et al., 2022), and a 6-month trial pairing 200 mg a day with exercise improved erectile function and testosterone in about half the men studied (Leitão et al., 2021). The label does not say whether Primal Storm uses a standardized extract, as those trials did, or a plain powder.
The adaptogens: Panax ginseng and ashwagandha
Ginseng and ashwagandha come fourth and fifth by weight. Both are traditional adaptogens, studied more for fatigue and stress than for any single men's-health outcome.
Panax ginseng has two systematic reviews behind it. One found modest evidence it eases fatigue, at roughly 200 mg to 3 g a day, with few side effects (Arring et al., 2018). A second, on red ginseng for erectile dysfunction near 1,800 mg a day, called the evidence suggestive but too thin to be firm (Jang et al., 2008).
Ashwagandha sits fifth. A crossover trial in aging, overweight men gave 600 mg a day of a standardized extract for 16 weeks and found it raised DHEA-S and testosterone versus placebo, though vitality and well-being improved about equally in both groups (Lopresti et al., 2019). Primal Storm shares its 838 mg across five other ingredients, unlikely to reach 600 mg alone.
Yohimbe: the sixth ingredient, and the one that needs the most care
Yohimbe extract is the final ingredient on the label, meaning the smallest share of the 838 mg blend. Smallest share does not mean safest.
Yohimbe bark contains yohimbine, the compound behind its effects. A 1998 meta-analysis of 7 trials in 419 men found purified yohimbine beat placebo for erectile dysfunction at known doses of about 15-30 mg a day (Ernst et al., 1998). That evidence predates modern ED drugs and says nothing about an unregulated extract of unstated strength.
NCCIH links yohimbine to cardiac arrhythmia, blood pressure problems, heart attacks and seizures, and reports that yohimbe poison-control callers needed medical care more often than other supplement callers (National Center for Complementary and Integrative Health (NCCIH), 2025). A 2016 lab analysis of 49 commercial yohimbine supplements found content ranging from none detected to 12.1 mg per serving; only 22% of products even listed an amount, and among those, measured content ranged from 23% to 147% of the label claim (Cohen et al., 2016). Primal Storm states no amount at all, so none of that can be checked here.

What Primal Storm's ingredient label doesn't tell you
Reading every word on the label still leaves real gaps. A proprietary blend is legal to sell this way; some questions have no printed answer.

Per Operation et al., 2023, a proprietary blend keeps a shopper from knowing their real exposure to any one ingredient in it. Full transcription: Primal Storm Supplement Facts.
Ingredients: common questions
What are all 6 ingredients in Primal Storm?
Tribulus, horny goat weed, longjack (tongkat ali), Panax ginseng, ashwagandha and yohimbe, in one 838 mg blend.
How much of each ingredient does Primal Storm contain?
Not published. A proprietary blend prints only the combined 838 mg total, not each ingredient's own amount.
Which ingredient is the largest share of the blend?
Tribulus terrestris. Blend ingredients print by weight, and tribulus is listed first.
Which ingredient is the smallest share?
Yohimbe extract, listed last, even though it carries the blend's most serious safety profile.
Which ingredient has the best human research?
Longjack (tongkat ali). Pooled trials link it to higher testosterone at 100-600 mg a day in men with low baseline levels.
Can 838 mg hold research doses of all 6 ingredients?
Not likely. Tongkat ali, tribulus and ashwagandha alone were studied at doses that add up to more than 838 mg.
Is yohimbe safe in a proprietary blend?
It carries real risk alone, and an undisclosed dose makes that risk harder to judge. See our full side-effects breakdown.
Does Primal Storm publish extract standardization?
No. The label names each herb but states no extract ratio or standardization for any of the six.
