SARM Stacking Guide: Best Combinations, Protocols & Safety Concerns

Bulking Stack

• LGD-4033: 5-10mg/day
• RAD-140: 10mg/day
• Duration: 8 weeks
• Expected: 10-15 lbs muscle
• Suppression: Severe—comprehensive PCT required

Cutting Stack

• Ostarine: 20mg/day
• Cardarine: 10-20mg/day (PPARδ agonist, NOT a SARM)
• Duration: 8 weeks
• Expected: Muscle preservation + fat loss
• Warning: Cardarine carries cancer risk (animal studies)

Recomp Stack

• Ostarine: 20mg/day
• LGD-4033: 5mg/day
• Duration: 8 weeks
• Expected: 5-8 lbs muscle + fat loss

Suppression

Stacking compounds suppression exponentially, not additively:

• Single SARM: Moderate suppression
• Two SARMs: Severe suppression
• Three+ SARMs: Near-complete shutdown

Liver Stress

Multiple oral compounds increase hepatotoxicity risk:

• Both compounds processed through liver
• CYP450 enzyme competition
• Cumulative bile duct stress

PCT Complexity

• Longer PCT duration (6-8 weeks vs 4)
• Higher SERM doses potentially needed
• HCG often required
• Recovery timeline: 12-20 weeks

Beginner (NOT Recommended to Stack)

First-time users should run single compound to assess tolerance.

Intermediate

• Two compounds maximum
• 8 weeks duration
• Moderate doses
• Full PCT protocol

Advanced

• May stack 2-3 compounds
• Requires blood work monitoring
• Comprehensive PCT with HCG
• Minimum 8-week recovery between cycles

Dual SARM Stack PCT

• Weeks 1-2: Tamoxifen 40mg + Clomiphene 50mg + HCG 3000IU EOD
• Weeks 3-4: Tamoxifen 20mg + Clomiphene 25mg
• Weeks 5-6: Tamoxifen 10mg + Clomiphene 12.5mg

Ancillary Support

• DHEA: 100-200mg/day
• NAC: 1200mg/day (liver)
• Milk Thistle: 1000mg/day
• Tongkat Ali: 400mg/day
