Ligandrol (LGD-4033) interactions
with RAD-140
Avoid · moderateStacking strong SARMs at full dose maximizes HPTA suppression and lipid disruption. Use only one anabolic SARM at a time at meaningful doses.
Timing: Do not run 3+ SARMs concurrently
with Ostarine
Caution · mildCombining two SARMs increases suppression beyond either alone. Ostarine is milder than LGD — this stack is more manageable than RAD+LGD but still requires bloodwork monitoring and PCT consideration.
Timing: Use Ostarine 10–15 mg with LGD 5 mg; monitor testosterone levels
with RAD-140
Caution · moderateBoth are highly suppressive SARMs — stacking significantly increases HPTA suppression and may require aggressive PCT. Combined androgenic load increases hair loss risk in predisposed individuals.
Timing: Use lower doses of each if stacking; run no longer than 8 weeks
with RAD-140
Caution · moderateBoth are potent SARMs with significant testosterone suppression. Stacking amplifies suppression without proportional benefits. PCT required after either, especially together.
Timing: Avoid stacking unless experienced — run one SARM per cycle for better assessment
with RAD-140
Caution · highBoth LGD-4033 and RAD-140 are among the most suppressive SARMs. Stacking them without exogenous testosterone can lead to severe hypogonadism. Full PCT required post-cycle.
Timing: Avoid stacking these two aggressive SARMs — suppression is severe
with Cardarine
CompatibleLGD-4033 drives strength and lean mass; Cardarine offsets the cardiovascular impact and supports conditioning.
Timing: Co-administer daily for lean bulk or recomp
with MK-677
Compatible · lowPopular lean mass stack. LGD-4033 is one of the most suppressive SARMs — expect testosterone suppression requiring PCT. MK-677 non-suppressive and complementary.
Timing: Run MK-677 year-round; LGD-4033 in 8–12 week cycles with PCT
