Welcome to the forum, glad you found us!
However there is one big question I should start off with, namely why do you want to do it yourself, as opposed to getting it done properly by a doctor?
While both injections and stirring have been done by many, they also have considerable medical risk, starting with infection, general trauma and so on, so we really try to discourage it. It also doesn't work that well as a castration method (though it can certainly make you sterile)
You don't say where you are posting from, and I know that some countries are not sympathetic to our desires, but in a lot of the world there is now a definite path to not only castration, but to the entire reassignment surgery (going by your profile, it sounds like that is what you'd really want to end up with eventuallly - tell me if I'm wrong)
The World Professional Association for Transgender Health (WPATH) has released their "Standards Of Care, Version 8" which we usually refer to hear as the "SOCv8" - it's a free download at
https://wpath.org/publications/soc8/ - I strongly advise downloading a copy and reading at least the Eunuch and Mental Health chapters, and probably most of the rest given your goals. Then do a search for Transgender centers in your area and reach out to them... It is a lengthy process and you have to convince a lot of doctors along the way that this is something you really really want, but it is straightforward and safe. In many places it will also be covered in large part and often totally by your health insurance.
If you live in a place that isn't supportive, there are also many options for 'medical tourism' to get surgery. This route is more expensive, but can be quicker and simpler.
You have an advantage in some ways, as the TG centers are far more used to dealing with patients wanting to do full binary transitions than those like me that want to stay in the 'mushy middle'
While I definitely do NOT encourage it, if you are really determined to follow the do it yourself path, we recently managed to import the message base from the previous version of the forums, which gives us over 25 years of people's experiences, including several threads about alcohol and calcium chloride injections, and likely stirring, which can give you an idea about what others have done, and found did or did not work....
