Shared Safety Flags

2x 2 androgenic compounds (Oxandrolone, Primobolan). Additive androgenic load — increased risk of hair loss, acne, prostate effects.
2x 2 compounds share the carcinogenic-risk safety flag (Oxandrolone, Primobolan). Monitor accordingly.
2x 2 hepatotoxic compounds (Oxandrolone, Primobolan). Liver damage risk significantly increased. Include liver support (TUDCA/NAC) and monitor ALT/AST.
2x 2 HPTA-suppressive compounds (Oxandrolone, Primobolan). Deep hormonal shutdown expected — plan extended PCT.
2x 2 compounds disrupt lipids (Oxandrolone, Primobolan). Get lipid panel mid-cycle — consider adding lipid support.
2x 2 compounds share the teratogenic safety flag (Oxandrolone, Primobolan). Monitor accordingly.

Oxandrolone + Primobolan
Avoid

Both Oxandrolone and Primobolan carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently.
