Can research peptides be used alongside HRT (estrogen or progesterone)?

Some people do stack research peptides while on HRT, but that is not evidence that the stack is studied or safe. Anything that may change estrogen metabolism, inflammation, fluid balance, or IGF-1 can in theory change how HRT feels or how labs look. Lab work on DIM with transdermal estradiol, for example, shows metabolite-pattern changes and raises the possibility of blunting some estrogenic effect of menopausal hormone therapy. Run any add-on past the clinician who manages your HRT before you treat forum consensus as a protocol.
