You need to check TT, FT, E2 AND LH/FSH to see what the SERM is doing. If LH/FSH are lowish, your pituitary is the problem. If LH/FSH are high, your testes are the problem and hCG would have limited effects too.
Low prolactin is better than high, but perhaps that points to a pituitary insufficiency also notably if LH/FSH were low on the SERM.

Lethargy can easily also be from low thyroid function, often a result of not using iodized salt. You can eval thyroid function by checking oral body temperatures as per the thyroid basics sticky. Thyroid fT3 is part of the body’s temperature control loop and fT3 regulates mitochondrial activity in your cells, creating ATP, the foundation of your energy levels. Note that statin drugs can interfere with all of that in some individuals.
