here's an excerpt from the Open Gate Labs (diy hrt provider) site for anyone interested in homebrewing diy:

It does not take a chemist to make gel, sublingual or even injections small scale for personal use or to distribute locally. And that’s what you should learn to do. I won’t hold your hand throughout the entire process, but if you’re able to do some research on your own it’s not super difficult to do.

A few hundred dollars is all you need to get started, you’ll be doing yourself a favor and strengthening the decentralized flow of life saving medication that it seems like endless people want gone.

Known homebrewers are not going to be around forever. New people may be good, new people may be bad, what will you be? Please do what you can to support the DIY community.

diy is genuinely life saving for many people. of course, remember that there are risks present when purchasing and using home brewed hrt, and more when making it yourself, but with enough research and caution it's overall quite safe.
