Some people (usually non‐binary assigned female at birth) may prefer to use a lower dose of testosterone, sometimes referred to by patients as ‘micro‐dosing.’ There is no evidence to suggest that this results in less of the effects of standard testosterone doses, and certainly, all permanent effects can still occur, but it does allow more patient control over the speed of physical changes. To ensure cardiovascular and bone health, it is suggested that the testosterone level should be maintained above 5–6 nmol/L.
