I ordered this 400mg one from Symphony Labs:
Estradiol Enanthate (10 mL × 40 mg/mL)
I was planning to use this for a long time by injecting 4mg weekly with 30G insulin syringes but someone here told me it is recommended to trash it after 6 months.
Anyone used until the vial is empty like 2 years?


Look, with perfect conditions the vial should last until empty. I didnt mean to make you think that you cant empty it.
As with everything in life, its all about risk tolerance. Especially with diy, how much risk are you personally willing to accept? If you feel that you can empty it, then i cant and wont tell you you cant.
Do look for the things i mentioned in other thread, because that is important. But i made that thread because i had the same issue. I didnt want to throw that vial away. BUT i wasnt as careful as i am now with that particular vial, so i have not injected from it again. My second vial i have pushed past the 28 day thing, but thats because im sure i was careful. I guess my risk tolerance is low, i have a case with sanitized caps for the vials, wipe everything down before and after with alc pads, and i still wont go past 6 months. But thats also cause ill empty it before then
So ultimately, because youre doing diy, its up to you. Definitely research, like you have been, and feel free to ask questions. I want you to be able to empty your vial, and im rooting for you. I was just trying to tell you the things i heard, and am living by now. ❤️❤️
