Ownership disclosure: Better Man Report and JOYMODE share ownership. How we compare products.
OUR TAKE
Where it fits.
The Nitrosigine amount matches the 1,500 mg protocol in a published acute vessel-function study.
THE LIMITATION
Six capsules per serving. A matching ingredient dose does not prove this combination produces the same outcome or outperforms another brand.
01 / INSIDE THE FORMULA
What is actually in a serving?
Amounts below are per 6 capsules. Manufacturer directions and daily cost are listed separately.
| Nitrosigine (arginine silicate) | 1,500 mg |
|---|---|
| S7 proprietary botanical blend | 150 mg total; green coffee bean, green tea, turmeric, tart cherry, blueberry, broccoli and kale; individual amounts undisclosed |
| Trans-resveratrol | 90 mg |
| BioPerine black pepper extract | 15 mg |
The disclosure check
Nitrosigine, resveratrol and BioPerine individually disclosed; S7 is a proprietary botanical blend with only its total disclosed.
- L-citrulline
- Not in the listed formula
- Nitrate contribution
- Arginine silicate formula; no added nitrate ingredient
A proprietary blend may disclose its total weight while keeping individual amounts private. That limits dose comparisons; it does not establish that the product has no effect.
More label details, testing & evidence
Juvenon BloodFlow-7 Nitro XXXL · Sources checked September 8, 2026. Supplier specifications, certification listings and batch reports have different scopes; the notes below identify each.
| Other ingredients | Gelatin, microcrystalline cellulose and silica; the label also prints “vegetable magnesium and stearate,” an apparent excipient wording error. It does not establish an elemental magnesium dose.Sources: Juvenon — Supplement Facts |
|---|---|
| Botanical parts & marker | S7 identifies green-coffee bean, green-tea leaf and turmeric-root extracts plus blueberry, broccoli, tart cherry and kale; individual weights are proprietary. BioPerine is black-pepper fruit extract; Sabinsa specifies at least 95% piperine for that ingredient, not an assay of this bottle.Sources: Juvenon — Supplement Facts · Sabinsa — BioPerine ingredient specification |
| Caffeine & testing | Juvenon describes this formula as caffeine- and stimulant-free despite the coffee/tea ingredients, and states that every batch is third-party tested for purity/potency. No public report for a current lot was verified.Sources: Juvenon — BloodFlow-7 Nitro XXXL · Juvenon — brand testing statement |
| S7 evidence beyond the pilot | FutureCeuticals now describes a 90-day placebo-controlled S7 study as well as earlier acute research. The full newer report was not reviewed here. The eight-person acute pilot is therefore one research anchor, not a complete inventory of all S7 evidence. Neither validates the finished BloodFlow-7 combination.Sources: FutureCeuticals — S7 research summary |
Still unconfirmed: S7’s individual component/marker quantities remain proprietary; current-lot assays and finished-formula outcome trials were not verified.
02 / THE EVIDENCE
Does the claim hold up?
CLAIM CHECK
Does XXXL establish the strongest product?
A broad strongest-product claim would need a defined outcome and a credible comparison against the relevant alternatives. We have not verified that evidence. Nitrosigine is arginine silicate, not a nitrate dose. The S7 supplier also describes a newer 90-day placebo-controlled ingredient study; full methods were not verified here, and supplier research is not a trial of this finished formula.
Assessment: Comparative superiority not verified. Source checked September 8, 2026.
