I inject 200mg of testosterone cypionate every 2 weeks for hrt. i wanted to know what supplements i should i use everyday for this regimen?

None: Not only should you not take any supplements, you need to stop the testosterone unless it's being given for testosterone deficiency - in which case there is better and safer replacement, particularly in someone who already has gynecomastia. Check w/your physician.

DHEA: And perhaps Anastrozole 1 mg 3 times weekly to control the usual and customary increase in serum estradiols that comes with injectable therapy. However i would also like to question your injection interval or every fourteen days. The half life of test cyp int he body is 5 days, meaning in 5 days 50% of your dosing is gone. Your injection interval should be the usual and customary 7 days.
