Add peptides or compounds to check all pairwise interactions, cumulative organ load, and safety flags.

This stack requires monitoring: 1 interaction(s) need attention. No critical conflicts, but bloodwork and regular check-ins recommended.

Shared Safety Flags

2x 2 androgenic compounds (MK-2866, RAD-140). Additive androgenic load — increased risk of hair loss, acne, prostate effects.
2x 2 compounds share the carcinogenic-risk safety flag (MK-2866, RAD-140). Monitor accordingly.
2x 2 hepatotoxic compounds (MK-2866, RAD-140). Liver damage risk significantly increased. Include liver support (TUDCA/NAC) and monitor ALT/AST.
2x 2 HPTA-suppressive compounds (MK-2866, RAD-140). Deep hormonal shutdown expected — plan extended PCT.
2x 2 compounds disrupt lipids (MK-2866, RAD-140). Get lipid panel mid-cycle — consider adding lipid support.

MK-2866 + RAD-140
Monitor

Both are SARMs competing for the same androgen receptor. Stacking MK-2866 with RAD-140 will increase total androgenic load and significantly amplify HPTA suppression beyond what either compound produces alone. If combining, lower doses of each should be used, and bloodwork monitoring of testosterone, LH, and FSH is essential. Most users find RAD-140 alone sufficient and do not benefit meaningfully from adding MK-2866.
