Shared Safety Flags

2x 2 androgenic compounds (Anastrozole, Masteron). Additive androgenic load — increased risk of hair loss, acne, prostate effects.
2x 2 compounds share the aromatase-inhibitor safety flag (Anastrozole, Masteron). Monitor accordingly.
2x 2 HPTA-suppressive compounds (Anastrozole, Masteron). Deep hormonal shutdown expected — plan extended PCT.
2x 2 compounds disrupt lipids (Anastrozole, Masteron). Get lipid panel mid-cycle — consider adding lipid support.
2x 2 compounds share the teratogenic safety flag (Anastrozole, Masteron). Monitor accordingly.

Masteron's inherent anti-estrogenic properties often reduce or eliminate the need for anastrozole when running moderate testosterone doses. If both are used, estradiol should be monitored carefully to avoid over-suppression, which can impair joint comfort, lipid health, and bone mineral density. Many users find that adding Masteron to a testosterone cycle allows them to drop their AI entirely or reduce the dose significantly.
