Wikipedia unsurprisingly has some great information on transgender people and trans-related things.
https://en.wikipedia.org/wiki/Transgender_hormone_therapy_(female-to-male) – informational page regarding trans men (FTM)
https://en.wikipedia.org/wiki/Transgender_hormone_therapy_(male-to-female) – informational page regarding trans women (MTF)

https://en.wikipedia.org/wiki/Non-binary_gender – information page regarding non-binary info, people and the history of what being non-binary is as well.
https://en.wikipedia.org/wiki/Pharmacokinetics_of_estradiol – this is a really great resource for knowing the half-life, the length of time required for the concentration of a particular substance (typically a drug) to decrease to half of its starting dose in the body, of specific administration of estradiol. Such as patches, pills, injections, etc.
https://en.wikipedia.org/wiki/Pharmacokinetics_of_testosterone – The exact same thing exists for trans guys as well with testosterone.
A transgender therapist who is transgender herself made a big list of HRT providers in Texas and in the surrounding states such as Oklahoma and Louisana. I personally have gone to 3 people on this list. She did a fantastic job with making this list and I would defiantly recommend looking at her website if you haven’t already.
https://moderntranshormones.com/ – Beverly Cosgrove is a transgender woman and a trans medicine researcher who publishes her opinions on her website. She talks frequently about routes of administration of estradiol such as injections and about anti-androgens such a Spironolactone. I would recommend looking at her website if you haven’t already.
An important footnote, never take medical advice for your personal situation based off of what people on the internet say. Always be safe and talk to your doctor before changing your regimen or medication. The point of Beverly’s website and many others is to help start a conversation that you can have with you and your doctor.
http://www.ftmguide.org – This is an amazing website and overall guide for trans men. The author of the website, Hudson, created this website as an update guide of a book that he read as a kid. On this website you can find information ranging from hormonal to medical information to information about shoes and clothes. The website is all encompassing and has amazing information accessible for any reader who is interested or wanting to learn more about the topic. Hudson did an amazing job with his website and I would highly suggest anyone who wants to learn more about trans men related information, to check out his website.
https://www.abrathatfits.org/calculator.php – for trans women or non binary people struggling to find out what bust or bra size they are, a bra that fits, hopefully is here to help. The website has a calculator to try and give you a general idea of what bra size you might be. Not only that but they have a subreddit https://www.reddit.com/r/ABraThatFits/, for other ladies who might be struggling to find a bra that fits as well. For anyone who is growing boobs but isn’t comfortable with getting a professional measurement of them, websites such as a bra that fits can be very helpful.
UCSF, University California San Francisco, is one of the most prominent leaders in transgender care. On their website, they have fantastic information regarding the medical side of transgender care.

On the Revel and riot website, a website whose mission statement is to help LGBTQ+ individuals has an article called transgender 101. They have a lot of really good information, especially if you are newer to information on transgender individuals. I would personally recommend giving it a read:
https://www.psychiatry.org/patients-families/gender-dysphoria/what-is-gender-dysphoria – American Psychiatric Association has information on what Gender dysphoria is, and the qualification of being diagnosed with gender dysphoria for both kids and adults. For those who don’t understand what gender dysphoria is and want to learn more about it, websites such as this one can be a valuable resource.
Both of these are great guides for you to start understanding some of the complexities of hormones for both trans men and trans women.
