Is A Practical Guide to Feminizing HRT Relevant for Transmasculine People?

Partially, but it was not written for you. The guide's own foreword states that its primary audience is people considering feminizing HRT and established transsexuals, and that while "sections of this are still highly relevant" for transmasculine readers, "there are key differences in goals and outcomes." The author points to a separate masculinizing HRT guide instead, noting they had not examined it in full depth.

What the guide actually covers

The document is a community-written, living reference on feminizing HRT. Its stated purpose is to give "simplified direct answers to the most common questions on how to safely and effectively perform HRT," in contrast to community wikis the author considers impractical for people who want actionable guidance rather than every semi-relevant biological process and graph.

The author describes themselves as a layperson, not a doctor or medical professional, and frames the entire document as opinion rather than medical advice or statement of fact.

Where it may still be useful to you

• Understanding a partner's or friend's regimen. If someone close to you is starting or adjusting feminizing HRT, the guide's direct-answer format can help you follow what they are doing and why.
• General HRT literacy. Some mechanics of hormone delivery, monitoring, and self-advocacy carry across directions of therapy even when the specific drugs and targets differ.
• Navigating community resources. The author's critique of sprawling wikis and their warning to stay off certain trans subreddits (specifically /r/mtf, which they call "particularly bad") reflects a general stance on where to look for information, not a feminizing-specific one.

Where it will not serve you

• Dosing and regimen decisions. The guide's core content is built around feminizing goals. Applying it to masculinizing HRT would mean substituting an entirely different set of medications and targets the document does not address.
• Outcome expectations. The foreword is explicit that goals and outcomes differ. What counts as a successful result in this guide is defined by feminizing endpoints.
• A masculinizing reference. The author does not claim to provide one. They link out to a separate guide they describe as looking "pretty solid" but unexamined.

What to do instead

If you are transmasculine, treat this guide as background reading at most, and use your own judgment about anything you take from it. For your own regimen questions, go to a masculinizing-specific resource or a clinician. The author's own framing supports this: they wrote for a feminizing audience, flagged the limits of cross-applicability themselves, and deferred to a different document for your direction of care.

If you are non-binary, the same logic applies with an added caveat. The guide assumes a feminizing trajectory, so its relevance depends on whether your goals overlap with that trajectory, not on your identity label.
