blood work you need (at minimum):
1. Testosterone, Total
2. Testosterone, Free
3. Sensitive E2 Assay (Not basic estradiol, that's for women)
4. CBC (Compete blood count)
5. CMP (Comprehensive metabolic panel)
6. Lipid Profile (post cycle is fine)
7. LH and FSH (pre-cycle and post PCT)
These panels need to be done pre-cycle to ensure that your internals are ready for this ride. Mid-cycle to verify that your estrogen blocker dose is working, your blood isn't too thick, your liver is still safe and that your gear is legitimate and not fake or underdosed. Post cycle so that you can verify that you've completed your cycle safely and no issues need attention.
Here is your blood work timing:
Pre-Cycle blood work: 2 weeks prior to cycle.
Mid-Cycle blood work: 7 to 8 weeks into a 12 week cycle. Or 5 weeks into an 8 weeker.
Post-Cycle blood work: 6 weeks after PCT.
