Non-Binary and Low-Dose HRT
Most hormone services have a standard plan built around a full change in one direction. Plenty of people want something else. Some want some of the changes and not others, some want to go slowly and see how it feels, and some want a body that is not read clearly either way. Low-dose HRT, sometimes called microdosing, is how many of them approach it.
The honest summary is that a lower dose generally means slower and often smaller changes, not a choice of which changes you get. Hormones do not let you pick from a menu. Knowing that up front is the most useful thing on this page.
I am not a doctor and I have not taken hormones myself. I coordinate trans and non-binary patients through surgery in Bangkok, and a fair number of them started hormones at a low dose, changed their minds about the dose along the way, or stopped once they had the changes they wanted. This page is what I have learned from them and from the published guidance, which on this topic is thin.

What "low dose" and "microdosing" mean
"Low dose" usually means a dose below the standard starting or target dose for someone aiming at a full binary change, and a lower target for blood levels. There is no single figure; it is whatever you and a prescriber agree.
"Microdosing" is an informal term, mostly from community spaces, not a medical one. People use it for anything from a slightly reduced dose to a very small one. Because it has no fixed definition, two people who say they are microdosing may be taking very different amounts. If you use the word with a prescriber, say what you actually mean by it.
Some people also use a low dose as a starting point, to see how they feel before deciding whether to go further.
What a lower dose actually does
Hormones work on the same body systems whatever the dose. A lower dose tends to mean changes arrive more slowly and may stop at a smaller point, but the same kinds of changes happen, broadly in the same order. You cannot, for example, take a low dose of testosterone and get facial hair without any voice change, or a low dose of estrogen and get softer skin without any breast growth.
Some changes are sensitive to small amounts. On testosterone, voice deepening and clitoral growth can begin at low doses, and both are permanent. On estrogen, breast development begins early and is permanent once established. If there is a change you definitely do not want, that is the conversation to have with a prescriber before starting, not after.
Other changes, such as fat redistribution, skin texture, body hair and muscle, tend to be slower and more dose-dependent, and more likely to reverse if you stop. What changes, and when and the masculinizing timeline set out which is which. Is HRT reversible? goes into it further.
Before you start
Write down the two or three changes you most want and the one or two you most want to avoid, and take the list to your first appointment. It makes the conversation specific, and a prescriber can tell you straight whether a lower dose will get you there.
Stopping once you have what you want
Some people take a standard or low dose until they reach the changes they want, then stop or reduce. This works for the permanent changes: a voice that has dropped or breast tissue that has grown will stay. The reversible changes tend to drift back over the following months as your own hormones take over again.
Stopping or reducing is something to do with a prescriber, not alone. It affects periods, mood, energy and bone health, and a prescriber can plan it so it is not a shock.
The bone health question
Your bones need a reasonable level of some sex hormone, estrogen or testosterone, to stay strong. That matters most for people who have had their gonads removed or are taking something that suppresses their own hormones, such as a GnRH agonist or a strong anti-androgen, without replacing them fully.
If your plan lowers your own hormones and only partly replaces them, ask your prescriber how they will keep an eye on bone health. Long-term health covers it in more detail.
The evidence is thin
Almost all research on gender-affirming hormones has looked at standard doses aiming at a binary change. Low-dose and non-binary regimens have been studied far less, so nobody can give you a reliable table of what a given low dose will do over a given time. Prescribers are working from general knowledge of how the hormones behave, and from their own patients.
That does not mean it is unsafe or unwise. It means expectations should be loose, blood tests still matter, and the plan will probably be adjusted along the way. The WPATH Standards of Care, version 8, recognise non-binary people's goals and support individualised treatment, but they do not set out specific low-dose regimens.
Talking to a prescriber
Some prescribers are comfortable with non-binary goals and will build a plan around them. Others default to the standard regimen and need a clear explanation. Either way, describing what you want in terms of changes, rather than a label, gets a better answer.
Useful questions to ask:
- Which of the changes I want are likely at a lower dose, and roughly how slowly?
- Which changes I do not want are still likely, and are they permanent?
- What blood levels are you aiming for, and how often will you check them?
- If I want to stop or reduce later, how would we do it?
Monitoring is the same as on a standard dose. Informed consent services tend to be the most flexible about non-standard plans, and blood tests and monitoring explains what gets checked.
If a prescriber insists on the standard dose
Ask them to explain the medical reason. Sometimes there is one, often bone health if your own hormones are being suppressed. If the reason is only that it is their usual plan, it is reasonable to look for a prescriber who works with non-binary patients.
Frequently asked questions
What is microdosing HRT?
An informal term for taking hormones at a lower dose than the standard, with no fixed definition. Say what dose you actually mean when you talk to a prescriber. See what low dose and microdosing mean.
Can I choose which changes I get from hormones?
Not really. A lower dose slows changes and may make them smaller, but you get the same kinds of change, and some sensitive ones, such as voice deepening on testosterone, can start at low doses. See what a lower dose actually does.
Can I stop once I have the changes I want?
Some people do. Permanent changes stay, and reversible ones tend to drift back. Plan it with a prescriber. See stopping once you have what you want.
Is low-dose HRT safe?
It has been studied much less than standard doses, so expectations should be loose and monitoring still matters, including for bone health. See the evidence is thin and the bone health question.
