DHEA has many roles in the body, few are understood.
Some freely convert DHEA-->E2 in their adrenals, others not.
DHEA only increases testicular testosterone production when T production was rate limited by low DHEA. So don't expect that DHEA will increase your T levels just because there is more.
Less E2 might increase T by reducing E2's negative feedback signal on your HPTA.
If you want to get leaner, you need to know that your thyroid function is OK. Best way to check that is oral body temperature.

- also should get 98.6 mid-afternoon
- temps can be low if iodine deficient, not using iodized salt and/or vitamins listing iodine&selenium
