    1. How do I know if your product has the amount of minoxidil you claim?

    A. Very good question. You should ask the question when you shop high strength minoxidil online. 

    We have our product tested by an independent reputable USA lab to ensure that the concentration meets our specification

    You can see the testing result at the end of this page.

    As far as we know, there is no other supplier of 15.0% minoxidil that was tested and passed the specification. 


    2. I noticed that you have another product called Dualgen-15 With PG. How is it different from this product?

    A. We initially only offered Dualgen-15 NO PG.

    Later we added Dualgen-15 With PG  in response to the request of some of our customers.  

    These two products have the same effective ingredients (15.0% minoxidil, 5.0% azelaic acid, 0.025% retinol, and 0.001% caffeine) and are equally effective.

    The only difference is that DualGen-15 NO PG uses glycerin, whereas DualGen-15 With PG uses propylene glycol (PG) as the delivery vehicle.

    The use of glycerin in DualGen-15 NO PG eliminates any scalp irritation caused by propylene glycol that is seen in ~10% users.

    It also slows down slightly the drying time.

    So if you know you are allergic to propylene glycol, it is best to use DualGen-15 NO PG. Otherwise, you can consider DualGen-15 With PG.



    3. Why use a 5% or higher minoxidil solution when 2% – 5% minoxidil solutions are readily available over the counter in many countries? 

    A. Minoxidil displays a dose-dependent effect with higher concentrations, improving the responsiveness and greater regrowth of hair.

    The higher the effective dose of minoxidil, the better the result is.

    That is exactly the reason why 5% minoxidil gave better results than 2% (see below)



    4. Is 15% minoxidil safe?

     Answer:  Large clinical studies with thousands participants showed that minoxidil concentration had to be greater than 20 ng/mL to give systemic effects.

     5% minoxidil solution has 1.2 ng / mL of minoxidil in the serum. 

    Thus, there is more than a 16-fold safety margin from the use of 5% topical minoxidil

    There is more than 5-fold safety margin with the use of a 15% topical minoxidil solution assuming the serum concentration is tripled when the topical minoxidil is increased from 5% to 15%.

    In reality, the serum concentration should be less tripled.

    Thus the safety margin is more than 5-fold. 

    Nonetheless, the product has minoxidil, thus people are strongly recommended to be vigilant about all the listed side effects when using 15% minoxidil.

    We haven’t seen any customer who developed side effects with the use of azelaic acid in this formula yet.

    See the complete minoxidil side effects here.


    5. Can you tell me the solvent composition of your product?

    A. The solvent consists of Purified Water, Ethanol, and Glycerin. 

    We can't give the ratio of the solvents as it is our trade secret.

    We have done extensive experiments to optimize the solvent composition to ensure our products have the optimal absorption, usability and effectiveness. 


    6. Is a glycerin based formula less effective than a propylene glycol based formula with the same minoxidil concentration? 

    A. No. Both glycerin and propylene glycol are pharmacologically inactive ingredients in the minoxidil products.

    They are used in minoxidil solutions as solvent so minoxidil can be in solution form.

    In addition, their slow rate of evaporation allows the effective ingredients minoxidil to form a thin film on the scalp for continued absorption.


    7. Does minoxidil harm healthy hair? 

    A. Not at all. Although the exact pharmacodynamics of minoxidil is not well understood, the effect of minoxidil is to safely promote growth and to maintain maturity of the hair follicles.

    These effects are most observable in hair follicles affected by male pattern baldness (MPB).


    8. Why is azelaic acid added to 15% minoxidil solution?

     A: There are two main reasons why 15% minoxidil is usually compounded as 15% minoxidil with azelaic acid:

    1). It has shown in vitro study that azelaic acid is a strong DHT blocker.

    It reduces the DHT concentration in the scalp to reverse genetic hair loss (male pattern baldness) that is currently believed to be caused by the excessive DHT in the scalp.

    2). The other reason that is not so well known to the general public is that it actually helps the absorption of minoxidil.

    Minoxidil is a base, which likes to grab a proton in a solution and become an ionic molecule.

    Our skin does not absorb any ionic molecules (a molecule that is positively or negatively charged) very well.

    When azelaic acid is added, it will form azelaic acid-minoxidil complex, which is a neutral molecule and can be absorbed by our skin or scalp much more efficiently.


     9. If 15% minoxidil works better than 5%, why isn't there any big pharm company that offers it? 

     A: There are three reasons why big pharm company is not offering it.

    (1). Technical challenge.

    Very few companies in the world know how to compound 15% minoxidil.

    Believe it or not, most 15% minoxidil products available online are fake.

    They are either repackaged 5% minoxidil solutions or even no minoxidil at all.

    You can easily find out if a 15% minoxidil is real or not by having it tested by a reputable analytical lab.

    Arl Bio Pharma (http://arlok.com/) can test it for 150 US dollars.  


    (2). Prohibitively Expensive:

    Companies need to go through an FDA approval process to allow them to market the solution.

    The approval process can easily cost hundreds of million dollars, and it can take many years to complete the clinical trials.


    (3). Lack of Patent Protection:

    They don't have a patent for the use of higher than 5% minoxidil solutions to treat male pattern baldness, which means any company can make and sell it.

    For something to be patentable, one of the requirements is that it has to be something new that has never been disclosed to the public before.

    So even if a big pharmaceutical company decides to invest in 15% minoxidil and successfully gets FDA approval, it won't be able to patent it since this formula has long been used.

    Yes, if they can make a 15% minoxidil foam, they could patent the 15% minoxidil foam because no one has ever made such a product to our best knowledge.

    Without a patent, a big company won’t invest in it to get FDA approval because its profits cannot be guaranteed.

    Keep in mind that when big companies make decisions on investment, the first thing they consider is how much profit it can make, not how good a product is.

    If selling sugar water or junk food can bring them big profit, they will not hesitate to do so.


    10. Are all 15% minoxidil products the same?

     A: No. Part of the reason is mentioned in question 9.

    Most of the  15% minoxidil products are actually not real.

    In addition, the solvent vehicles and their amounts are different between brands, resulting in difference in absorption and usability and ultimately their effectiveness.

    Furthermore, the difference in auxiliary ingredients (such as finasteride, azelaic acid, retinol, and or caffeine) further differs one brand from another.


    11. Is 15% minoxidil  stable?

     A: The stability of 15% minoxidil varies depending on how it is compounded.

    If properly compounded, it has pretty decent stability.

    We have done stability study. It shows that It is stable for at least 3 years.

    All minoxidil products should be stored at room temperature

    Crystallization may occur if it is stored in a refrigerator. 

    If crystal is formed in a minoxidil solution due to improper storage, you can warm your 15% minoxidil bottle in hot water and shake the bottle for a few minutes to dissolve the crystals.


    12. How to use 15% minoxidil solution?

     A: It is typically recommended to use 15% minoxidil once a day in the evening.

    Because of the high concentration, it takes time to dry.

    If properly applied, most of the product should be absorbed by the scalp in 1 hour.

    It is also recommended to use a 5% minoxidil in the morning.


    13. Do you have any before and after photos to show it works. 

     A: we have many such photos sbumitted by customers. 

    Below is one example of using Dualgen-15 NO PG for six months.

    You can view more resutls here  (15% minoxidil results). 

    You can also read the customer reviews shown on each product page.

    14. Do you have anything stronger than Dualgen-15 NO PG?

    A. Yes. We do have stronger solutions available. 

    Please check out our Dualgen-15 NO PG Plus, and Dualgen-15 With PG Plus

    Both products have 15% minoxidil and topical finasteride at 0.1%.



  • best 15% minoxidil







  • (1). If you are not allergic to propylene glycol, you can choose our DualGen-15 With PG that is expected to be slightly less greasy than DualGen-15 NO PG.

    (2). This product is recommended to use once a day. You can use it with a lower strength of minoxidil product such as Dualgen-5 or Essengen. Using DualGen-15 NO PG in the evening is recommended because it takes slightly longer time to dry than a 5% minoxidil solution (such as DualGen-5 or EsseGen-5) because of the high concentration of minoxidil and the additional effective ingredients. 

    (3). If you want a product with stronger DHT blocking capability, you can try Dualgen-15 NO PG Plus or Dualgen-15 With PG Plus.

It working for me!
I’m going to keep using this product because it’s working for me!
Dualgen 15% No PG
I am very impressed with this product I myself started to see results in as little as 30 days.
Entrega en España a los ocho días del pedido, buen precio. Lo aplico directamente al cuero cabelludo, produciéndose el secado en muy poco tiempo, con molestias muy suaves, siento unos pinchazos flojos por ambos párpados durante unos minutos después del uso, debe ser por ir al 15% y ser más efectivo. No experimento en el cabello la sensación de quedar pegado ni aceitoso y picazones como otros minoxidiles. Lo llevo usando menos de un mes, y la puntuación es muy buena, y las sesiones las realizo rápidamente, con otras marcas me lleva más tiempo.
Fabulous results
Reasonably priced product, great results seen within 3 months. It does take a while to dry but my son used the solution with PG and got scalp irritation.
The delivery time to Hungary's excellent...
- Ordering such products regularly - Arriving before my expectation, i.e. within 1week, excellent
Faster results.
Dualgen 15 appears to work faster, causing new growth to appear quicker. I learned to apply it sparingly with the dropper in areas where most needed. My earlier use of a spray head was not good, in that it was noticeably tacky in the sprayed area for most of the day. The trick is to get it to the scalp area and not to saturate the overlying hair.
4.5 *
Geat results just takes time to dry.
Great trader. Product arrives super quick. Early days yet, but given the exceptional reviews I'm hoping for some good results.
Good, more potent/greater results than others
I am not a chemist. However, my opinion would be that the additional ingredients, Retinol, Caffeine, and ABN Complex are responsible for the better results of this product. I believe the mixture of the third additional ingredient cannot be published. Bottle states "TM". It would be helpful for the manufacturer to give a brief description of what the third ingredient's benefit is/are and why. Enough detail can be provided as to be helpful to us, the customer, without infringing on your privacy concerns.
Great product. Very fair price, great quality with labels that can be trusted. Rest assured when you purchase here.
very promising product. Using only for 3 weeks.
Got this last 3 weeks ago and started using. It's too early to conclude but it think my hair is showing signs of growth. I will continue using this for few months.
MonoxidilMax - cheap and effective alternative!
Yes! This product is cheaper than other similar products and is of high quality. 5 stars
6 years of buying from this seller
I’ve bought Dualgen and minoxidil etc from this seller since 2012. I have never once had a problem, or undelivered product, or items seized by customs. Just amazing, solid, reliable service for 16 years. I used Dualgen as a prophylactic measure when I had no hair loss whatsoever. My hair has gone slightly thinner over the years (I’m 60 next birthday) but my hairdresser, a trichologist, told me that I’d have huge hair loss by now if it weren’t for minoxidilmax.
Fast shipping, i'm looking fw. to see result
Amazing product!
Great results and excellent company!
great product
very quick from order to delivery. I use it with other products but after years of looking for something that works I do think I have finally found the right combination and I am now seeing growth.
Great producd
Will definitely deal with again. Fast shipping and Great producd
Works better than 5% Minoxidil
It definitely works better the lower concentration ones, I have been using minoxidil %5 for years it always works for me until recently it seems to stop working. Now I got the higher concentration and I back to track, my only complaint about it is it does not work that much faster, and it drys out you hair and scalp
can't be any happier
I'm a 45 year old man, I"ve been off of Propecia for over a year and started using DualGen 15 (DualGen 5 in the mornings) recently. Now a little over 2 months later there a large crop of smaller hairs coming in, almost like I have a second canopy-if you know what I mean. Also have noticeable growth on the front hairline. Very satisfied customer
Love it
Will definitely deal with again. Quick response. Fast shipping. Great product, exactly as described. A+++, Smooth transaction.
Way better than Rogaine
Had used Rogaine for 3 years prior to this. I didn't see any regrowth but had severe scalp irritation with Rogaine. I have zero irritation with this product and hair regrowth is very obvious after using it for half a year.
