Buying Bio-Identical Hormones: Overview and Advice

Buying bio-identical hormones isn't something you just do through a webshop or a foreign site: in 2026, it's the route through which you get them, not the packaging, that determines whether your treatment is safe and tailored to you. This overview places the five ways to obtain bio-identical hormones side by side, with the risks, the diagnostics, and the costs that come with each.

In short

• Buying bio-identical hormones through a compounding pharmacy with a BIG-registered doctor gives you the most control over dosage in 2026, provided blood monitoring continues.
• Unregulated webshops without a prescription lack diagnostics and monitoring: this is where the greatest risk of an incorrect dosage lies.
• Menovia combines blood, DNA, and microbiome testing with the DUTCH test before a BIG-registered doctor prescribes anything, within a program of at least 6 months.
• Since May 2026, part of the consultation costs at Menovia are reimbursed through supplementary insurance; compounded medication, DHEA, and testosterone fall outside this.

Why this matters

The discussion around hormone therapy is often flattened to the 2002 WHI study. That study examined women with an average age of 63 who combined conjugated equine estrogen with synthetic MPA, not bio-identical hormones in women around menopause. More recent French cohort research (E3N) shows that bio-identical progesterone combined with estrogen doesn't show a significantly increased breast cancer risk compared to synthetic progestogens.

That difference in composition is exactly why the route through which you obtain bio-identical hormones matters in 2026. Not every 'bio-identical' label guarantees the same purity, dosage, or guidance. For persistent symptoms, it's known what helps against hot flashes according to scientific research alongside hormone therapy, and that overview also shows why a bare purchase without a diagnosis achieves little.

How we assess these routes

This comparison assesses each route on four fixed points: whether diagnostics (blood testing and, for example, the DUTCH test) come before the first prescription, whether a BIG-registered doctor is involved in guidance, whether the medication is regulated and of known purity, and how transparent the costs are in 2026. The basis for this is the whitepaper 'Menopause: A Broader View', supplemented with guidelines from the North American Menopause Society (NAMS) and positions from the Dutch Association of Internal Medicine on hormone therapy.

None of the routes below get a standalone product label. This is medical care, not a purchase decision with a star rating.

The 5 routes to obtaining bio-identical hormones

1. Compounding pharmacy with a prescription from a BIG-registered doctor

A compounding pharmacy makes bio-identical estrogen or progesterone to order, based on a prescription tailored to your blood values. This is called compounded preparation: the dosage is put together per woman, instead of coming from a fixed box. In 2026, this compounded medication still falls outside the partial reimbursement that has applied to consultations since May 2026.

Advice: choose this route only in combination with ongoing blood monitoring, since an incorrect dose of bio-identical estrogen can cause symptoms just as easily as a deficiency can.

2. Regular pharmacy with a registered bio-identical preparation

GPs and gynecologists also prescribe registered bio-identical estrogen and progesterone preparations, available at any pharmacy. These preparations come in fixed doses, which is a major difference from compounded preparation.

Fixed doses don't always match the individual hormone levels that come out of blood testing. Advice: usable as a starting point, but always ask for a follow-up measurement after 12 weeks, since a fixed dose doesn't produce the same hormone level in every woman.

3. Online menopause clinic with diagnostics beforehand, such as Menovia

Menovia only has a BIG-registered doctor prescribe after testing: blood testing, DNA testing, microbiome analysis, and/or the DUTCH test. Since May 2026, part of the consultation costs are reimbursed through supplementary insurance, depending on your policy. Advice: suitable for those who want a tailored treatment plan without the waiting time of a physical clinic, provided you check in advance what your policy covers, since compounded medication, DHEA, and testosterone remain out of pocket. What a good clinic should offer is covered further in what to look for in a hormone therapy clinic.

4. Unregulated webshops and foreign sites without a prescription

Sites offering bio-identical hormones without a prescription, often as a cream or powder, provide no blood testing and no monitoring. The concentration on the label doesn't always match what's actually in the product.

“A dosage without blood testing is gambling, not treatment.”

Advice: skip this route. Without blood testing and doctor oversight, you don't know whether the dosage is too high or too low, and an incorrect dose of bio-identical progesterone can cause side effects that no one follows up on. In addition, the medication may contain unsafe substances.

5. Phytoestrogens and supplements that call themselves 'bio-identical'

Plant-based substances like soy isoflavones are often sold as a natural alternative to bio-identical hormones. Chemically, they aren't identical to the estradiol your own body produces, even though the marketing isn't always clear about that.

Advice: don't use these supplements as a replacement for hormone therapy with moderate to severe symptoms. They can serve as an addition alongside lifestyle changes, not as a replacement for a medically grounded program.

Comparison table: which route fits your situation

What to look for before buying bio-identical hormones

• Always ask for blood testing before the first prescription. Without FSH and estradiol values, no one knows whether the dose is right; an FSH value above 25 to 30 IU/L often points to menopause.
• Check whether the prescriber is BIG-registered. This can be looked up in the public BIG register and is just as important with an online program as with a physical doctor.
• Check reimbursement before you start. Coverage varies by insurer and policy, and since May 2026 applies only to consultations, not to compounded medication, DHEA, or testosterone.
• Ask about the monitoring schedule. Good guidance doesn't just repeat blood testing every 12 weeks, but combines this with a monthly consultation with a doctor and the MRS questionnaire to track your symptoms.
• Ask whether GLP-1 medication is relevant as an addition, not as a replacement. Within a program, GLP-1 medication within a program can be used alongside bio-identical hormone therapy and lifestyle, never as a standalone alternative.

Frequently asked questions

Can you just buy bio-identical hormones online without a prescription?

No, responsible use requires a prescription from a BIG-registered doctor after blood testing. Webshops without a prescription offer no diagnostics and no monitoring, which makes the dosage unreliable.

What's the difference between bio-identical and synthetic hormones?

Bio-identical hormones are molecularly identical to the hormones the body itself produces, synthetic variants like MPA aren't. The E3N study shows that this difference in composition is linked to a different breast cancer risk profile.

Is bio-identical hormone therapy safe according to recent research?

The 2002 WHI study examined synthetic hormones in women with an average age of 63, not bio-identical hormones around menopause. More recent cohort research such as E3N shows no significantly increased risk for bio-identical progesterone combined with estrogen.

What does a program with bio-identical hormones cost in 2026?

An online program like Menovia's costs €75 to €199 per month, with an intake of €350 to €1,299 depending on the chosen program. Compounded preparation at a pharmacy has a separate price per compound that varies by pharmacy.

Is bio-identical hormone therapy reimbursed?

Since May 2026, part of the consultation costs are reimbursed through supplementary insurance, depending on your policy. Compounded medication, DHEA, and testosterone aren't registered in the Netherlands and aren't reimbursed.

How long does it take before bio-identical hormones work?

The first effects usually become noticeable within 12 weeks, the point at which the first follow-up measurement takes place. A full program runs for at least 6 months to properly adjust dosage and symptoms.

Can you combine bio-identical hormones with GLP-1 medication?

Yes, GLP-1 medication such as semaglutide or tirzepatide can be used as an addition alongside bio-identical hormone therapy and lifestyle, never as a replacement. This is assessed by a doctor on a case-by-case basis.

What is a DUTCH test and why is it needed before you get hormones?

The DUTCH test measures hormones and their breakdown products through urine and gives a more detailed picture than blood testing alone. At Menovia, this is one of the four diagnostic pillars before a BIG-registered doctor prescribes anything.

In conclusion

The most underestimated step in buying bio-identical hormones isn't the choice between cream or tablet, but the blood monitoring that follows afterward. A program that measures nothing after the first dose isn't treatment, it's a gamble, even if the label says 'bio-identical.' Those starting in 2026 would do well to choose a route where diagnostics and follow-up measurement are a standard part, not an extra you have to demand yourself.
