This is how the tranny cartels make their estrogen
They purchase "pharmaceutical grade" estradiol, which is fairly easy to procure.
Then, they mix this with some cheap solvent and antibacterial and sell them at low prices to people without prescriptions.
I cannot stress this enough: THIS ESTRADIOL IS FOR EXPERIMENTS ON CELL LINES AND NOT FOR HUMAN CONSUMPTION
So little is being done about this that the even use regular postal services to drug mentally ill and confused kids/young people.
