I have E2V oil, but decided to start with oral. There aren't too many domestic sources of estradiol valerate oil, and Turkish Pharm has it domestically, but you gotta buy at least $200 of stuff and the E2V is 100mg/mL, so dilution is required, which requires filtering (unless your BB is already sterile and my is not) and all that. Way too much work, but once you have it, you will have a pile of it for a very very long time. Ordering via India in small ampules seems more productive; this is what I did. Oral seemed easier to start experimenting with.
Damn, u clearly know ur stuff! Thanks for the estradiol valerate lesson! Lol
