So I am hypothetically, allegedly, possibly, asking for a friend about info regarding to DIY hrt. What are common pitfalls to avoid, people's favorite sources and ways to stay safe wile doing DIY. firstly, is coffee.hrt a good aggregator for pharmaceutical sites? Secondly, on average, how long can the results of estrogen be hidden before it become obvious? Thirdly, where can I find good dosage charts. Lastly, if I can't access or afford blood testing, how do I keep dosage safe and effective?
1- Yes, it is a good aggregator.(I assume you mean hrt dot coffee)
2- Hiding effects really depends on the people around you and how much they know about hormones. Only person I know who got figured out due to changes was from an accepting family which had multiple trans friends. They were boymoding because they themselves were a chud and their family was woke, which is a rare situation. As long as you hide the hormones themselves you should be fine for one or two years.
3- As others said Transfemscience is a great source.
4- If you follow the guidelines and get effects your dose is probably fine. Of course hormone tests are the only reliable way to know but getting the effects at the normal times is the second best way to know things are going well. Also you probably know this but do not try at home testosterone tests, they are unreliable for trans women.
