Ate there any studies measuring estrone levels for equipoise , at different doses, say 150, 300, 450, and 600 mgs ?
Estrone causes collagen tissue production to stimulate ? , skin elasticity, and memory protection
I still say EQ cannot convert directly to estrone, only estradiol because it has a 17-hydroxyl group, not a 17-keto group. Aromatase only modifies the A-ring, it does NOT do anything at C17 which is on the opposite side of the steroid molecule. And there’s no other enzyme besides aromatase to produce estrogens of any type in the body - both in women and men, they are all converted by aromatase from androgens.
Now once EQ is converted to estradiol, it can be converted again into estrone, and similarly estrone can be converted to estradiol, via 17β-HSD enzymes, which are expressed to varying degrees in different tissues. So estrone is both a metabolite and precursor to estradiol and vice versa - normally estrone acts as a reservoir for estradiol production - except in post-menopausal women when it becomes the dominant estrogen (from adrenal DHEA) and as you likely know they typically develop major low estrogen symptoms, including male body fat distribution, hot flashes, accelerated ASCVD, body hair growth, low energy/libido, aches and pains, etc - that’s without HRT of course.
Some, maybe all of the Δ1-testosterone group may inhibit 17β-HSD1, in different people to varying degrees, which would cause a relative rise in E1 and relative decrease in E2. E2 is up to 100x as potent as E1 at receptor transactivation, so it doesn’t take much extra E1 to have an inhibitory effect on E2 - it basically acts as a competitive inhibitor when attached to an ER.
And I am aware of lab results showing high E1 in EQ users. Either it’s from excessive 17β-HSD1 inhibition in those people, or they have some new enzyme yet to be discovered.
