Hormone replacement therapy (HRT) can help transgender women who are transitioning build muscle, but generally not to the same extent as for those who went through a testosterone-dominant puberty. The effects vary based on factors like genetics, lifestyle, diet, and exercise routine.
Muscle building on feminizing HRT
For transgender women starting HRT, any muscle building effects are modest compared to what can be achieved naturally by men. This is because testosterone is a crucial hormone for building muscle mass. However, estrogen HRT does not directly hinder muscle growth either.
- With feminizing HRT, some retaining of existing muscle mass is possible with strength training
- Muscle mass decrease may occur due to lower testosterone levels
- Fat redistribution to hips/thighs typical on estrogen can make building leg muscle difficult
Promoting muscle growth
Here are some tips to help maximize muscle growth potential while on feminizing HRT:
- Strength train consistently - this stimulates muscle protein synthesis
- Eat enough protein - aim for 0.7-1g per pound of body weight
- Stay adequately hydrated and get enough rest
- Use good form and progressive overload
- Work both upper and lower body
- Lift moderately heavy weights with higher reps
Muscle changes timeline
The timeline for muscle changes from feminizing HRT includes:
- 1-3 months - Possible start of lean mass loss if not strength training
- 6-12 months - Noticeable muscle mass and strength decreases
- 2 years - Most muscle and strength loss has occurred
So keeping up with strength training is important, especially in the first 1-2 years. The longer on estrogen HRT, the harder it becomes to maintain muscle. Genetics and fitness levels also impact timelines.

Building significant muscle mass
For transgender women who wish to build levels of muscle mass approaching male averages, the options are limited due to the effects of estrogen HRT. Possible avenues include:
- Use of androgens like testosterone by some transgender female athletes
- Short-term discontinuation of HRT - health risks make this generally inadvisable
- Postponing estrogen HRT if in early transition stage
- Considering use of selective androgen receptor modulators (SARMs) - research is limited regarding effects and safety
As with anyone, transgender women should have realistic expectations when it comes to muscle building. Factors like genetics, diet, lifestyle and hormone levels play key roles in determining individual responses. Open conversations with health providers are important when considering changes to transition-related care plans.
Health considerations
There are some health factors for transgender women to consider as well when looking to build muscle mass:
- Increased muscle mass may make fat redistribution more difficult
- Can negatively impact breast development
- Potential for elevated hemoglobin/hematocrit levels
- Unknown impacts on cardiovascular and metabolic health
Monitoring weight changes, bloodwork, and risk factors is wise if intentionally trying to bulk muscle mass considerably above female typical levels.
Conclusion
* Some muscle retention is possible for transgender women on HRT, with dedicated strength training
* Building muscle like birth-assigned males is unlikely due to lower testosterone
* Realistic expectations are important - genetics constrain potential
* Seeking supervised use of androgens/SARMs if aiming for more muscle
* Health monitoring advised if purposely bulking up muscle long-term
