No User Rating for now

Though in its initial stages of clinical testing, CB-03-01 seems to be one of the most promising drugs for a wide range of applications. The drug may even replace a class of medications known as finasteride in the days to come.

CB-03-01 is an external anti-androgen and has grown quite popular with many people suffering from problems of hair loss etc.

In this review, we will try to find out more about this drug, its usage, its advantages, and side-effects, if any.

Basic Drug Information

Let us begin by looking at the necessary information about this drug and every pertinent information available in this regard. It is a topical anti-androgen that displays good skin penetration. Cosmo has patented this compound, and investigations and studies are on under the name Breezula.

Some Basic Details of this drug:

  • MW – 402.52
  • CAS – 19608-29-8
  • Purity – 98 percent

Application and Functions

The drug is in its clinical testing phases, and though the effects of the drug on bodybuilders are not proven, anecdotal evidence shows their results. The drug is supposed to take externally and, as such, does not enter the human bloodstream. As such, it does not affect the healthy hormone system in humans. It does not have any effect on your testosterone levels as well.

Its vast applications include treatment of hirsutism, hair loss, acne, etc. Its effects are still a subject of comprehensive study, but there have been many testimonials of users benefiting from the drug. It is, in fact, the only topical anti-androgen that has been approved as a hair loss prevention treatment.

CB-03-01 works differently – it is not an inhibitor like Dutasteride and Finasteride, but it leaves the androgen levels as they were but competes with androgen receptors.

So what are the benefits? Let us find out.

The Benefits

The compound is said to have significant benefits in cases of extensive hair loss and to help people grow some hair who have gone completely bald. Comprehensive studies are underway to develop this compound as a medicine to prevent hair loss and induce hair growth.

The best results are experienced when this drug is taken as a preventive aid following a proactive approach. This is also one of the safest treatments that you can rely on. It does not affect the endogenous hormonal profiles at all. If the user has been using this compound before hair loss or once the first signs of hair loss are seen, it helps in maintaining the best hair for years.

The Limitations

Apart from the benefits, there are certain downsides of using this compound as well, which is listed as under:

1. Price

The price of this compound is, in fact, the most significant limitation. There are very few companies that are selling it as of now, and all of them are selling it at extremely high prices.

2. High Dosage Required

To achieve good results, you would need anywhere between 150 to 450 mg of this drug, and that means more quantity required, which can go up to $100 to $300 per week.

3. Efficacy

In some isolated cases, it may not be that effective at all, and that means that it would need some additional compounds for them to show some results.

Now that we have seen the benefits as well, the limitations let us find out more.


The ideal dosage that can show any visible results is 150 to 450 mg per day, and that is dependent on the scalp area on which the compound is applied. There may be a need for a 7.5 percent solution required to be used twice a day. The FDA does not approve the mixture, and so the dosage guidelines mentioned above are purely based on user testimonies and observations.

It is recommended that you buy from companies which stock natural compounds and thus selecting companies of particular repute is advisable.

Final Verdict

With all that being said and done, we can comfortably conclude that CB-03-01 is a promising compound; however, it is still to emerge as a standalone therapy or hair treatment solution.

We will still have to wait till this compound gets approved by the FDA and maybe is available at a price that is affordable by all.
