Choosing a Male Performance Supplement: A Maxorin Buyer's Checklist
Quick answerScore six things before you buy: full amounts or a proprietary blend, studied doses, third-party testing for hidden drugs, an authorized seller, a written refund policy and the price per day. Scored honestly, Maxorin earns 17 of 30. It does well on seller, refunds and price, and loses points for blend amounts and an unpublished lab certificate.
What should a male performance supplement checklist cover?
A good male performance supplement shows what is inside, in amounts you can check. It comes from a seller you can reach, with a refund policy you can use. Six points cover all of that, for any capsule, powder or gummy.
Score each point from 1 to 5, for 30 in total. Further down, we run Maxorin through the same test and show every score.
1. Full amounts
Every ingredient named, each with its own amount per serving.
2. Studied doses
Amounts near what human trials actually used.
3. Tested for hidden drugs
An outside lab result tied to a lot number.
4. Authorized seller
A named seller with a phone and an address.
5. Refund policy
A set window, a way to claim and a returns address.
6. Price per day
The checkout total divided by days of use.
Point 1: Does the label show full amounts or a proprietary blend?
Start with the Supplement Facts panel. A full label lists each active ingredient with its own amount. A proprietary blend lists one total weight for a group of ingredients.
Federal rules let a blend show only its total, as long as the ingredients appear in order of weight (21 CFR 101.36). So the first ingredient is the largest and the last is the smallest. You still cannot see how much of each is inside.
Give 5 points for full amounts on every ingredient. Give fewer as more of the formula hides inside a blend.
Point 2: Are the doses close to what studies used?
Next, line up each amount with the dose human trials used. A product can name a studied ingredient and still hold far less than the tested amount. The name alone tells you little.
How to check
Find the study behind each ingredient and note the daily dose. Compare it with the label. With a blend, you can work out a ceiling for each ingredient by dividing the blend weight by its place in the list. Our post on how to read a proprietary blend label shows the math step by step.
What the numbers look like
The table below compares Maxorin's label with the study doses. A lower dose is not proof that an ingredient fails. It does mean the product is not the dose that was tested.
| Ingredient | Maxorin (per serving) | Doses used in studies | Gap | Source |
|---|---|---|---|---|
| L-Citrulline | At most 570 mg (first in blend) | 1,500 mg a day | Whole blend is 38% of it | (Cormio et al., 2011) |
| L-Carnitine | At most 285 mg | About 4 g a day (two carnitine forms) | Whole blend is 14% of it | (Cavallini et al., 2004) |
| Pine bark extract | At most 190 mg | 80-120 mg a day, always with 1.7 g arginine | Could fit; no arginine in Maxorin | (Stanislavov & Nikolova, 2003) |
| Maca root extract | At most 142 mg | 1,500-3,000 mg a day | At most about 10% of it | (Gonzales et al., 2002) |
| Grape skin extract | At most 114 mg | No human ED data; resveratrol 30-270 mg | Cannot compare | (Wong et al., 2011) |
| Saffron extract | At most 95 mg | About 30 mg a day | Could fit; amount not published | (Maleki-Saghooni et al., 2018) |
| Vitamin B3 (niacin) | 20 mg | Daily need 16 mg; upper limit 35 mg | Printed amount; within limits | (NIH ODS, Niacin) |
| Zinc | 11 mg | Daily need 11 mg; upper limit 40 mg | Printed amount; meets the need | (NIH ODS, Zinc) |
Point 3: Has an outside lab tested for hidden drugs?
This point matters most for safety. The FDA does not approve dietary supplements before they reach the market (FDA, Q&A on Dietary Supplements). Testing is up to the maker, and results are not always shared.
Male performance products carry a special risk. The FDA has found hidden sildenafil and tadalafil in many products sold as supplements (FDA, sexual enhancement notifications). In 2026, it warned about one sold as "natural" that held both drugs (FDA, X10 notice, 2026).
What good testing looks like
Look for a certificate of analysis from an outside lab. It should name the lot number on your bottle and show a screen for drug compounds. A logo alone is not a test result.
Why hidden drugs are dangerous
Hidden ED drugs can drop blood pressure to a dangerous level when mixed with nitrate heart medicines. If you take nitrates, talk to your doctor before using any product in this category.
Point 4: Are you buying from an authorized seller?
An authorized seller can confirm your order, your lot and your refund. A random marketplace listing often cannot. Buying from the named source also cuts the risk of fakes.
Score this point on what you can reach. Look for a named company, a phone number, a street address and an email that someone answers.
For Maxorin, the seller is Maxoerin, the licensed U.S. retail desk. It is a retailer, not the manufacturer. The order desk is +1 (323) 348-1373. The where to buy page lists the official route.
Point 5: Is the refund policy written and usable?
A refund policy should be written down, with a time limit, a way to claim and a returns address. Vague promises such as "satisfaction guaranteed" with no details score low.
Questions to ask
How many days do you have, and do they count from purchase or delivery? Who pays return shipping? How long does the money take to come back?
Maxorin gives 60 days from purchase. You call the order desk with your order ID and mail the bottles to 280 Park Avenue, Floor 19, New York, NY 10017. Refunds post 3-5 business days after the return is credited, then take 5-10 days to show on the card. Full details are on the refund policy page.
Point 6: What is the real price per day?
List prices and "savings" can hide the real cost. Price per day is a fairer number. Divide the checkout total, shipping included, by the days the order lasts.
At one capsule a day, each Maxorin bottle lasts 30 days. Tap a pack below to see its daily cost.
The 2-bottle pack adds shipping at checkout, so its true daily cost is a little higher. See the pricing page for each pack.

What red flags mean you should walk away?
Some claims are warning signs on any product in this category. If you see one, walk away or check with a pharmacist first.
"Works like Viagra"
A supplement is not a drug. A product that acts like one may contain one.
Results in minutes
Fast, drug-like effects are a sign of a hidden ingredient.
No label or no company
No Supplement Facts panel, address or phone means no one to hold to account.
Cure or treat claims
Supplements may not claim to treat ED or any disease.
Only sold in gas stations or pop-up sites
The FDA often finds tainted products in these channels.
No refund details
A promise with no window or address is hard to use.

Maxorin buyer's checklist FAQ
What is a proprietary blend?
It is a group of ingredients listed under one total weight. The label must list them in order of weight, but it does not have to show how much of each one is inside.
Why compare a label with study doses?
Trials tested set amounts. If a product holds far less than the tested amount, the trial result may not apply to it.
How can a supplement hide a drug?
The FDA does not approve supplements before they are sold. It has found hidden sildenafil and tadalafil in many products marketed for sexual enhancement.
Has Maxorin published a lab certificate?
Not yet. The pack shows lot MAX-26/MA-8307 and a certificate reference, MAX-8307-26-MA. These are references only, and no lab certificate has been published.
Who is the authorized seller of Maxorin?
Maxoerin is the licensed U.S. retail desk for Maxorin. It is a retailer, not the manufacturer.
How do I work out the price per day?
