Disclaimer
The FDA disclaimer as printed on the label, four things this product’s readers should know, and how this site is paid.
Written and reviewed by the Protoflow Editorial Desk · Last updated September 24, 2026
Quick answer
† These statements have not been evaluated by the Food & Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease. Nothing on this site is medical advice. The capsule shell is gelatin. Niacin is 75 mg against a 35 mg adult upper limit. Three ingredients each affect bleeding. Urinary and erectile symptoms are medical questions first. This site earns a commission if you order through it, which does not change your price.
Regulatory
The FDA statement, and what it actually means
This is the page we would ask you not to skim. Most disclaimers are written to be unreadable on purpose. This one is written to be used, because the product this site describes is sold against symptoms that are sometimes the first sign of something needing an appointment.
The FDA statement, as printed on the label itself
† These statements have not been evaluated by the Food & Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.
Printed on the wrap itself, in a boxed rule, tied by a dagger to both of the front-of-label claims. This is what a correctly disclaimed structure/function claim looks like, and the label gets it right.
No dietary supplement is approved before it is sold
This is the point most often misunderstood in this category, and it is not a criticism of any particular product. ODS states it plainly: “The U.S. Food and Drug Administration (FDA) does not determine whether dietary supplements are effective before they are marketed.” What exists instead is a responsibility placed on the company: “Supplement companies are responsible for having evidence that their products are safe, and the label claims are truthful and not misleading.”
So the rules a label follows are these. A structure/function claim may A structure/function claim may “describe the role of a nutrient or dietary ingredient intended to affect the normal structure or function of the human body, for example, ‘calcium builds strong bones.’” A disease claim says a product can “diagnose, treat, cure or prevent any disease”, which only an approved drug may do. Those claims are not pre-approved by anybody before the bottle goes on sale.
Nothing on this website is medical advice
No page here diagnoses anything, none recommends a treatment, and none is reviewed by a clinician — no doctor and no formulator is named anywhere in the material this site was given. These pages read a label and check it against federal reference pages. That is useful, and it is not the same thing as care. Do not start, stop or change any medicine because of something you read here.
Specific to this bottle
Four things this product’s readers should know
General disclaimers are easy to ignore because they apply to everything and therefore to nothing. These four apply to this bottle.
The capsule is gelatin, and this product is not vegetarian
The other-ingredients line on the wrap reads, word for word: “Rice Flour, Gelatin, Magnesium Stearate, Silicon Dioxide, Maltodextrin, Soy Protein Concentrate, Water.” Gelatin is made by boiling down animal collagen — skin, bone and connective tissue, usually bovine or porcine. It is the second ingredient in that row, which on a capsule product means it is almost certainly the shell. The supplied marketing pack ships a round VEGETARIAN mark with a carrot in the middle of it. Those two things cannot both be true of the same bottle.
This site prints the label. If you avoid animal products for religious, ethical or dietary reasons, that line decides the question.
Niacin at 75 mg is over its upper limit
The panel declares niacin (vitamin B3) at 75 mg, marked 469% of the Daily Value. The arithmetic is right: the Daily Value is 16 mg and 75 divided by 16 is 469%. The amount is the question. NIH ODS sets the upper limit for adults at 35 mg of niacin from dietary supplements — this serving is more than double it — and reports that supplements with 30 mg or more of nicotinic acid can make “the skin on your face, arms, and chest turn red and burn, tingle, and itch”, which “can also lead to headaches, rashes, and dizziness”. The label does not say which form of niacin it uses, and nicotinic acid and niacinamide behave differently. That single missing word is the difference between a harmless row and a flushing one.
The limit applies to your total intake, not to this bottle’s share of it, so add in any multivitamin before you judge the row. ODS on long-term high-dose use: it “can cause liver problems, including hepatitis and liver failure.”
Three ingredients in this bottle each affect bleeding
Three of the fourteen rows carry the same published warning, and they are in the same capsule. Vitamin E, per NIH ODS, “can increase the risk of bleeding in people taking anticoagulant or antiplatelet medicines, such as warfarin (Coumadin)”. Ginkgo, per NCCIH, “may increase the risk of bleeding in people who are taking anticoagulant drugs, such as warfarin”. Asian ginseng, per NCCIH, “may worsen autoimmune disorders and interfere with blood clotting”. None of those three amounts is extreme on its own. The point is that they arrive together, in one bottle, taken twice a day, by an age group that is more likely than most to be on a blood thinner already.
If you take warfarin or anything else that thins the blood, or you have surgery coming, this is a pharmacist conversation before it is a purchase.
Urinary and erectile symptoms are medical questions first
This is what the page exists for. MedlinePlus on an enlarged prostate: “An enlarged prostate is when your prostate gland becomes larger than normal. It’s also called benign prostatic hyperplasia or BPH for short.” It is common with age, which is exactly why the next sentence matters: “It’s important to see your health care provider if you have any of these symptoms because they could be from a more serious health problem.”
And on erectile difficulty, MedlinePlus is equally direct: “ED can be a sign of health problems. It may mean your blood vessels are clogged. It may mean you have nerve damage from diabetes.” Which is why “if you have ED, you should tell your doctor”
Neither is a supplement question. If a product bought for a symptom makes it easier to wait out a symptom that should have been examined, it has done harm even though the capsules themselves were harmless.
Safety
Interactions, the caution panel, and who should not take this
Protoflow prints its own caution panel, and it is the right instruction for this formula: If you are currently taking any medication, consult with a physician prior to use. Do not exceed suggested use.
Interactions
Tell whoever prescribes for you, and your pharmacist, everything you take — including this. NCCIH: “Some dietary supplements may harm you if you have a particular medical condition or risk factor or are taking certain prescription or over-the-counter medications.” And the instruction that follows: “Take charge of your health—talk with your health care providers about any complementary health approaches you use.”
The specific conversations are these. Vitamin E, ginkgo and Asian ginseng are the bleeding stack above. Ginseng has two more: NCCIH reports that it “Asian ginseng may worsen autoimmune disorders and interfere with blood clotting.” and that it “Asian ginseng might lower blood sugar levels.”, which makes it a conversation for anyone with an autoimmune condition or on diabetes medicine. Hawthorn has a duration limit rather than an interaction: “No research studies have tested whether it is safe to use hawthorn for more than 16 weeks.” A six-bottle supply is half a year.
Seven ingredients with no federal safety summary
Epimedium, damiana, muira puama, catuaba, tribulus, oat straw and cayenne have no NCCIH page and no ODS fact sheet. That is not a finding of harm. It does mean that for seven of the eleven botanicals here there is no federal safety statement to check an interaction against — worth saying to a pharmacist rather than assuming somebody has checked.
Pregnancy, nursing and under-18s
For completeness, because the label does not name these groups. NCCIH reports that saw palmetto “Saw palmetto may be unsafe for use during pregnancy or while breastfeeding.” Nobody pregnant or breastfeeding should take this formula without asking a clinician first, and nobody under 18 should take it at all — the storage line says KEEP OUT OF REACH OF CHILDREN, and this site treats the product as being for Adults 18 and over.
No trial of this formula, at these amounts, has been published or was supplied to this desk, and nothing on this website predicts what will happen to you.
Earnings disclosure
How this website is paid, and what it publishes anyway
This website earns money, and you should know how. The order button points at the brand’s own information and sales page, where the checkout is operated by BuyGoods. This site earns a commission if you buy through it. That does not change your price. We do not print the address as text anywhere, and the earnings disclosure is on the disclaimer page.
What that does and does not change
It does not change your price: the commission comes out of the seller’s margin, and it gives this desk no access to your order or your card details. What it does mean is that this site has a financial interest in you pressing a button, and the only honest response is to publish what argues against pressing it as plainly as what argues for.
So, on the page where it costs the most: the capsule shell is gelatin while the marketing ships a vegetarian seal; the niacin row is more than twice its adult upper limit; three ingredients each carry a published bleeding caution; seven of the eleven botanicals have no federal consumer page and three of the other four report no benefit; not one botanical carries an extract ratio; and the label prints no contact route at all. Those sentences cost this site money and they stay.
And the part that is genuinely good
Said in the same voice, because a disclaimer that only accuses is not honest either. Fourteen ingredients, fourteen amounts, no proprietary blend. In a men’s botanical formula that is genuinely unusual — a blend is normally where this category hides how little of each herb is in the capsule. Here every figure is printed and every figure can be checked. The front-of-label claims are careful, disclaimed and name no condition. Every criticism above exists only because this label publishes enough to make it possible.
No customer testimony is published here
The supplied pack describes its own review block, in its own words, as “layout copy only”, and three of its eight named buyers carry the same sentence word for word. None of it is published here.
Where the facts on this site come from
Amounts, claims, cautions and contact details are read off the supplied wrap label. Context comes from MedlinePlus, NCCIH, ODS and the FDA.

Questions
Protoflow FAQ: disclaimer questions
Is it vegetarian?
<strong>No.</strong> The other-ingredients line reads “Rice Flour, Gelatin, Magnesium Stearate, Silicon Dioxide, Maltodextrin, Soy Protein Concentrate, Water.” Gelatin is made from animal collagen. The marketing pack ships a vegetarian roundel; the label contradicts it, and the label is the document that counts.
Is the niacin a problem?
It is the row to ask about. 75 mg is more than twice the 35 mg adult upper limit for niacin from supplements. ODS reports that 30 mg or more of nicotinic acid can make “the skin on your face, arms, and chest turn red and burn, tingle, and itch”, and that long-term high-dose use “can cause liver problems, including hepatitis and liver failure”. The label does not say which form it uses.
Should I use this instead of seeing a doctor?
No, and MedlinePlus makes the reason concrete rather than abstract: “ED can be a sign of health problems. It may mean your blood vessels are clogged. It may mean you have nerve damage from diabetes.” On urinary symptoms it is equally plain that they “could be from a more serious health problem”.
Does the FDA approve supplements like this?
No. ODS: “The U.S. Food and Drug Administration (FDA) does not determine whether dietary supplements are effective before they are marketed.” FDA’s own description of its role is that it can act against an adulterated or misbranded product “after it reaches the market”.
Do you earn money if I buy through this site?
Yes. The order button leads to the brand’s own sales page and this site earns a commission if you buy. That does not change your price, and it has not changed a word on these pages — you are currently reading a site that tells you the vegetarian seal is wrong.
