Blood Pressure Support — Nitric Oxide / Amino Acid Formula
PressPril: A Disclosed Formula, a Shared PO Box, and a Misquoted Citation
PressPril's sales page doesn't sit at presspril.com's own homepage — it's hosted at a separate, non-obvious address, which is why an earlier pass at this page couldn't find it. Now that we've found it: the ingredient panel is genuinely disclosed with real per-ingredient doses, which is more than we can say for several sibling products we've reviewed. But the distributor's PO Box is shared with at least four other unrelated brands we've separately researched, the ZIP code printed on the label doesn't match the one on the sales page, and the sales page's own pull-quote misattributes a citation to a completely unrelated study.

Guarantee60 days, one-time payment, no subscription
An earlier pass at this page checked presspril.com's own homepage, which loads a generic, unbranded Jekyll hosting placeholder with no product content — and concluded no live product existed. That conclusion was wrong: the real sales page sits at a separate, non-obvious path on the same domain, not linked from the homepage itself. We're correcting the record here rather than leaving the earlier, incomplete finding up.
The real sales page is live and complete
It has a full hero section, three pricing tiers, an ingredients section with a printed Supplement Facts label, a 60-day guarantee, an FAQ, and a references section citing eight named studies. This is a normal, functioning sales funnel — it just isn't reachable by visiting the domain's own root address.
The checkout tracking script still has placeholder text in it
The page's own BuyGoods tracking snippet contains the literal text "REPLACE_ACCOUNT_ID" in two places in its source code, even though the actual "Buy Now" buttons link to a working checkout with a real account ID. That's sloppy, unfinished implementation on the vendor's side — not something that affects whether an order goes through, but a sign the page hasn't been fully cleaned up before going live.
The ingredient panel
To PressPril's credit, the printed Supplement Facts label discloses an individual milligram amount for every active ingredient — it does not hide behind an undosed "proprietary blend," a pattern we've flagged as a real gap on several other products.
Per-capsule amounts, as printed on the label
Niacin 7.5mg (47% DV), Calcium as calcium carbonate 18mg (1.5% DV), L-Arginine (base) 200mg, L-Arginine AKG 2:1 Extract 200mg, L-Citrulline HCl 100mg, L-Citrulline Malate 100mg, Beta Alanine 40mg. Other ingredients: hypromellose (vegetable capsule), vegetable stearate, silicon dioxide. One capsule per serving, 30 servings per bottle.
The underlying compounds are real and studied
L-Arginine and L-Citrulline are both nitric-oxide precursors with real published research on blood pressure, cited both on the vendor's own page and independently confirmed by us below (see Sources). That's a genuine point in the formula's favor — the ingredients aren't invented, and the doses aren't hidden.
Worth knowing: published dose ranges in the cited research for L-Citrulline typically run from 3,000–6,000mg per day in trials showing a measurable blood-pressure effect, taken as a standalone supplement. PressPril's combined L-Citrulline content (HCl + Malate) is 200mg per capsule — noticeably lower than the doses used in the trials it cites. We're not saying the formula does nothing at this dose; we're saying the label's own numbers are worth comparing against the research it points to, which is exactly what the citation section below is for.
Company & distributor
PO Box only, and a ZIP code that doesn't match itself
The printed label lists: "Distributed by: PressPril, PO Box 12730, Ogden, UT 84412." The sales page's own text, in its Supplement Facts caption, lists the same PO Box with a different ZIP code: "PO Box 12730, Ogden, UT 84404." Same box number, two different ZIP codes, on two pieces of the vendor's own material.
The exact same PO Box appears on other, unrelated brands
PO Box 12730 in Ogden, UT is not unique to PressPril. In separate research on other products for this same portfolio of review sites, we've found this identical PO Box number used as the distributor address for MemoHoney, BrainMary, Glyco Eden, and Honey Peak Gelatin — none of which are related to PressPril by product category or apparent manufacturer. A shared commercial mailbox used across multiple, unrelated supplement brands is consistent with a mail-forwarding or fulfillment-service address rather than a dedicated company location.
Support email domain doesn't match the brand
The label lists a support contact at "healthycostumer.us" — a domain name unrelated to "presspril.com" or the PressPril brand name itself (and, going by the spelling, likely intended to read "healthycustomer").
A citation that doesn't match its own reference list
PressPril's sales page quotes the same study twice — once as a pull-quote partway down the page, and again in its own numbered references section at the bottom. The two citations don't agree with each other.
The pull-quote cites the wrong paper entirely
The page's mid-page pull-quote attributes a statement about L-Citrulline and blood pressure to "Yang HH, et al., Nutr Metab (Lond). 2019;16:88," listing PMID 31889977. We looked that PMID up directly: it belongs to a real, published paper — but on an unrelated topic ("X-ray microtomography and linear discriminant analysis enable detection of embolism-related acoustic emissions," a study about tree branches, published in Plant Methods). It has nothing to do with L-Citrulline, blood pressure, or human physiology at all.
The page's own reference list gets it right
The same page's numbered references section, quoting what appears to be the identical study, correctly lists it as "Yang HH, Li XL, Zhang WG, Figueroa A, Chen LH, Qin LQ. Nutr Metab (Lond). 2019;16:89," PMID 31889969 — which we independently confirmed is the real, correct paper: "Effect of oral L-citrulline on brachial and aortic blood pressure defined by resting status: evidence from randomized controlled trials," published in Nutrition & Metabolism. So the real paper is genuinely cited once, correctly, on PressPril's own page — it's just contradicted by a second, incorrect citation of the same paper elsewhere on that same page.
We're not saying this was deliberate — mismatched citation numbers are a common copy-paste error in mass-produced sales pages built from templates. But it's a real, independently-verifiable error sitting on the vendor's own page today, and it's the kind of thing worth checking yourself rather than assuming every citation on a supplement sales page points where it claims to.
The "-Pril" name
"PressPril" combines "press" (as in blood pressure) with the suffix "-pril" — the real, standardized ending used for a class of prescription blood-pressure medications called ACE inhibitors: lisinopril, captopril, enalapril, and ramipril are all real, FDA-approved prescription drugs. PressPril's actual formula contains none of those drugs or anything chemically related to them — it's an amino-acid and nitric-oxide-precursor blend, a different mechanism entirely. The name is a marketing choice, not a claim of drug content, but it can read as more clinically credible than an unregulated dietary supplement actually is. At least two other supplements, BloodPril and Bazopril, use the same "-Pril" naming pattern; we have no evidence connecting either of them to PressPril's manufacturer.
Looking for a more heavily-dosed, single-ingredient option instead?
PressPril's own cited research is real — L-Citrulline and L-Arginine genuinely have published blood-pressure trials behind them. But the doses in those trials (typically 3,000–6,000mg of L-Citrulline per day) run well above PressPril's combined 200mg per capsule. A standalone, higher-dosed L-Citrulline or beetroot-nitrate supplement gets you closer to the amounts the research actually tested.
What it actually is: a standardized beetroot capsule disclosing a specific per-serving amount (550 mg) and naturally occurring nitrate content on the label — the same active pathway (dietary nitrate → nitric oxide) that PressPril's own cited research is built around.
Why we're pointing here instead: a higher, disclosed dose of the same active pathway, from a manufacturer with a normal, findable retail listing and no shared-PO-Box pattern.

Frequently asked questions
Is PressPril a scam? We didn't find evidence of that — the ingredients are real, the doses are disclosed, and the guarantee terms are stated plainly (60 days, one-time payment, no subscription trap). What we did find are transparency gaps: a PO Box shared with several unrelated brands, a ZIP code that doesn't match itself between two of the vendor's own materials, and a mismatched citation on its own sales page.
Is PressPril the same thing as BloodPril or Bazopril? We have no evidence that it is. Those are separate products sharing the same "-Pril" naming convention.
Why isn't there a "Buy Now" link to PressPril's own checkout on this page? Given the shared-PO-Box pattern and the ZIP code inconsistency, we're not comfortable sending readers to a checkout we can't fully verify the company behind. We've linked to a single-ingredient alternative with a more heavily-dosed, disclosed active ingredient instead.
Does Living Well Weekly sell PressPril directly? No. We're an independent research page; we don't process orders or hold inventory for any product.
Bottom line
PressPril is a real product with a real, disclosed ingredient panel — genuine amino-acid compounds at stated doses, not an undosed proprietary blend. That's a real point in its favor. But the distributor's PO Box is shared with at least four other, unrelated brands we've separately researched, the ZIP code printed on the label contradicts the one on the sales page, and the sales page's own pull-quote cites a completely unrelated study by mistake (even though the correct citation appears elsewhere on the same page). None of that proves the product doesn't work — the underlying compounds are real and studied — but it's enough inconsistency in the company's own materials that we're not comfortable linking to their checkout. If it's the nitric-oxide/blood-pressure angle that interests you, a higher-dosed, single-ingredient alternative is the more verifiable way to try it.
