| Category | Capsule supplement marketed for male stamina, libido, and virility, centered on supporting “endothelium” function and nitric oxide production |

| Guarantee | 90-day 100% money-back guarantee |
What Is EndoPump?
EndoPump is a dietary supplement sold through ClickBank and marketed to men who want to support stamina, libido, and overall virility. The official sales page frames its approach around the endothelium, the thin layer of cells lining blood vessels, and its role in nitric oxide production, which the vendor says is “the essential missing piece when it comes to a healthy libido.”
The product is presented through a long-form sales page featuring a doctor persona (referred to as “Dr. Leo Shub,” described as having worked with executives at several well-known companies) who is credited with the formula. We could not independently verify this backstory, and readers should treat it as unverified marketing narrative rather than a documented credential.
EndoPump comes as capsules, sold in single-bottle and multi-bottle bundles, with the vendor recommending consistent daily use to notice results.
Ingredients
The EndoPump sales page lists the following active ingredients, along with the general benefit each is claimed to support. Note that specific per-ingredient dosages (milligram amounts) are not published on the sales page, so it is not possible to independently assess whether the amounts used match the levels studied in the cited research:
| Ingredient (as labeled) | What It Is Claimed To Do |
|---|---|
| Vitamin E | cited by the vendor for supporting endothelial function and healthy libido levels |
| Niacin | cited for supporting healthy endothelium function |
| Horny Goat Weed Extract | cited for endothelial function, energy levels, blood flow, and stamina |
| Muira Puama Powder | cited for libido, stamina, and latency |
| Tribulus Terrestris Extract | the vendor cites a study showing a “78.1% increase in virility and stamina” and nitric oxide function support |
| Turnera Diffusa Leaf (Damiana) | cited for stamina and libido support |
| Ginkgo Biloba Powder | cited for fighting endothelial oxidative stress |
| Oat Straw Powder | cited for libido, performance, and mood support |
These are all commonly studied ingredients in the men’s health supplement category, and several (horny goat weed, tribulus terrestris, damiana, oat straw) show up frequently in similar ClickBank offers. The citations on the sales page point to general research on these ingredients individually, not to any clinical trial of the finished EndoPump formula itself, so the vendor’s specific numeric claims (like the 78.1% figure) should be read as describing an ingredient-level study, not a result users should expect from taking EndoPump.
How Does It Work?
The vendor’s core pitch is that supporting the endothelium, and by extension the body’s natural nitric oxide production, can help blood flow, which it ties to stamina, libido, and virility. This is a real area of cardiovascular and men’s health research in general (nitric oxide’s role in vascular function is well documented), but that is different from evidence that EndoPump’s specific capsule, at whatever doses it contains, produces those effects. The sales page does not publish any clinical testing of the finished product, so claims about how well it works are based on the vendor’s description of individual ingredients rather than trial data on EndoPump itself.
Pros and Cons
Pros
- Ingredient list is disclosed by name on the sales page, unlike some competing offers that hide their formula entirely
- Uses several ingredients (horny goat weed, tribulus terrestris, damiana) with a reasonable body of general research behind them
- Sold through ClickBank, which means a standardized checkout and refund process
- 90-day money-back guarantee is longer than many competitors’ 30- or 60-day windows
- Simple capsule format with free U.S. shipping on all bundle sizes
Cons
- No milligram dosages are published for any ingredient, so buyers can’t compare the formula to clinically studied amounts
- No clinical trial or third-party testing of the finished EndoPump product is cited, only general ingredient research
- The “FBI-surgeon” origin story built around Dr. Leo Shub cannot be independently verified and reads as promotional narrative
- The 78.1% “increase in virility and stamina” statistic is attributed to a single cited ingredient study, not to EndoPump as a finished product
- Per-bottle price rises for smaller orders ($71 for one bottle vs. $44/bottle on the 6-bottle bundle), which is a common upsell structure worth budgeting for
Pricing & Where to Buy
Pricing shown on the order page at the time of this review was tiered by bundle size:
| Bundle | Price | Notes |
|---|---|---|
| 1 bottle | $71 | $71 per bottle; one-time purchase or “Subscribe & Save 10%” auto-ship option |
| 3 bottles | $159 | $53 per bottle; listed by the vendor as the most popular option |
| 6 bottles | $264 | $44 per bottle; lowest per-bottle price on the page |
All bundles ship free within the U.S. EndoPump is sold exclusively through the official site and processed by ClickBank, which handles the checkout and refund request process. We recommend buying only through the official page linked in this review to make sure your order is covered by the vendor’s guarantee and ClickBank’s standard buyer protection, and to avoid third-party resellers.

Is EndoPump Legit or a Scam?
EndoPump is not an outright scam in the sense of taking payment and delivering nothing. It is a real supplement sold through ClickBank’s established affiliate and payment infrastructure, which includes a standard refund process. That said, several aspects of the marketing are worth approaching with caution:
- The doctor-discovery narrative (an “on-call” physician for major companies who allegedly discovered the formula) is a common storytelling device in this niche and is not independently verifiable from the sales page.
- Specific ingredient dosages are not disclosed, which is a transparency gap compared to supplements that publish a full Supplement Facts panel.
- The headline statistic (a “78.1% increase in virility and stamina”) comes from research on one ingredient in isolation, not a trial of EndoPump itself, a distinction the sales page does not make clearly.
- The 90-day money-back guarantee is a genuine consumer protection if honored as described, and ClickBank’s role as retailer of record gives buyers a standardized dispute path if a refund request is denied.
Overall, EndoPump reads as a fairly typical entry in the ClickBank men’s health category: real, commonly studied ingredients presented with more marketing flourish than clinical substantiation. Buyers should weigh the disclosed ingredient list and refund window against the lack of dosing transparency and product-specific testing before committing to a multi-bottle order.
Frequently Asked Questions
What’s in EndoPump?
The official sales page lists Vitamin E, Niacin, Horny Goat Weed Extract, Muira Puama Powder, Tribulus Terrestris Extract, Turnera Diffusa Leaf (Damiana), Ginkgo Biloba Powder, and Oat Straw Powder, but does not publish the dose of each ingredient.
Is EndoPump safe?
The listed ingredients are commonly used in men’s health supplements, but without published dosages we can’t fully evaluate safety at the amounts EndoPump actually uses. Talk to a doctor before starting, especially if you take medication or have an underlying health condition.
How long until I see results?
The vendor recommends taking EndoPump consistently and backs it with a 90-day guarantee, which suggests they expect results to take time to build rather than appear immediately. Individual results will vary.
What is the refund policy?
EndoPump is covered by a 90-day, no-questions-asked money-back guarantee according to the sales page. Purchases are processed through ClickBank, so refund requests go through ClickBank’s standard process as well as the vendor’s own support line.
Where can I buy EndoPump?
EndoPump is sold exclusively through its official ClickBank order page. We have not seen it offered through major retailers, and buying elsewhere would not be covered by the vendor’s guarantee.
Final Verdict
EndoPump combines a handful of genuinely well-studied men’s health ingredients, including horny goat weed, tribulus terrestris, damiana, and Ginkgo biloba, with a marketing narrative (the “FBI-surgeon” backstory, the uncontextualized 78.1% statistic) that outruns what the sales page can actually document. The ingredient disclosure and 90-day guarantee put it ahead of ClickBank offers that hide their formula entirely, but the missing dosages and lack of finished-product testing mean buyers are still trusting the vendor’s word on how much of each ingredient they’re getting. It’s a reasonable option to try within the guarantee window for someone who has already researched these ingredients and wants to see how the combination works for them, not a product we’d call a clear must-buy.
Before you buy: this product’s official sales page may present its claims more confidently than the independent research on its ingredients currently supports. Read the breakdown above, weigh it against the vendor’s own marketing, and decide for yourself before you check out.
