Estradiol and Estradiol Valerate both come up in the same conversations; they overlap on estrogen receptors and menopausal symptoms. Estradiol: Estradiol, often abbreviated E2, is a steroid hormone and the most potent of the naturally occurring estrogens, the principal group of female sex hormones. Estradiol Valerate: Estradiol valerate is an estrogen medication and an ester prodrug of estradiol, the main natural estrogen.
Estradiol, often abbreviated E2, is a steroid hormone and the most potent of the naturally occurring estrogens, the principal group of female sex hormones. Produced chiefly by the ovaries, it governs the development of female secondary sexual characteristics and the menstrual cycle, and it also plays important roles in bone, brain, and cardiovascular health in both sexes. As a medicine it is used in menopausal hormone therapy, hormonal contraception, feminizing hormone therapy for transgender women, and the treatment of certain hormone deficiencies. It is available in many forms, including tablets, patches, gels, and injections.
Estradiol valerate is an estrogen medication and an ester prodrug of estradiol, the main natural estrogen. Once in the body it is split by enzymes into estradiol and valeric acid, so its effects are essentially those of estradiol itself. It is used in menopausal hormone therapy, as part of some hormonal contraceptives, in feminizing hormone therapy for transgender women, and, historically, in the palliative treatment of prostate cancer. It is taken by mouth as a tablet or given as a long-acting oil injection into muscle.

strengths are the entries' qualitative ratings (strong / moderate / weak); Ki and EC50 figures appear where an entry records them.
easiest to source: Estradiol is currently listed by more trusted vendors (2), so it's the simpler one to get hold of. for effects and safety, read each full entry; this is educational, not medical advice.
