Shared Safety Flags

2x 2 compounds share the teratogenic safety flag (HCG, Letrozole). Monitor accordingly.
~
HCG + Letrozole
Monitor

HCG stimulates intratesticular aromatase activity directly, producing estradiol independently of peripheral aromatization. This can partially counteract letrozole's systemic aromatase inhibition. When combining HCG with letrozole, be aware that estradiol levels may be less suppressed than expected, and dose adjustments may be needed. Monitor bloodwork.
