Can You Stack SARMs? And Is It Worth It?

SARMs (Selective Androgen Receptor Modulators) are a hot topic in bodybuilding research for their ability to boost muscle growth, strength, and fat loss with fewer side effects than steroids. But can you stack SARMs to amplify results, and is it worth it? This post explores the individual science, history, and benefits of key SARMs and compounds available at APH Science, then dives into the pros and cons of stacking them, highlighting top stacks like the Bulking Stack, Alpha Stack, Lean Muscle Stack, and Mega Bulking Stack.

Individual SARMs and Compounds: Science, History, and Benefits

MK-677 (Ibutamoren)

• What Is It? A growth hormone secretagogue that mimics ghrelin, boosting GH and IGF-1. Dosed at 10-20 mg daily for 8-16 weeks.
• History: Developed by Merck in the 1990s for growth hormone deficiencies, it’s now researched for muscle growth and recovery.
• Science: Increases GH/IGF-1 by up to 50% in trials, enhancing protein synthesis. Studies show 1-2 kg lean mass gains in 16 weeks without training, 2-3 kg with training in 8-12 weeks.
• Benefits:
  • Muscle growth (2-3 kg in 8-12 weeks)
  • Improved sleep and recovery
  • Fat loss (5-7% body fat reduction)
  • No PCT needed (non-suppressive)
• Considerations: May cause water retention or hunger spikes. Bloodwork advised.

RAD-140 (Testolone)

• What Is It? A SARM targeting muscle and bone receptors. Dosed at 10 mg daily for 8-12 weeks.
• History: Developed by Radius Health in the 2000s for muscle-wasting conditions, popular for bulking.
• Science: Binds androgen receptors (Ki ~7 nM), activating mTOR for protein synthesis. Trials show 3-4 kg lean mass gains in 4-8 weeks, with 20-30% strength boosts.
• Benefits:
  • Rapid muscle growth (3-4 kg in 4-8 weeks)
  • Significant strength gains
  • Fat loss (3-5% body fat)
  • PCT required due to testosterone suppression

• History: Developed by GlaxoSmithKline in the 1990s for metabolic health, adopted for endurance and fat loss.
• Science: Upregulates CPT1A and PDK4 genes, increasing fat oxidation. Rodent studies show 50-70% endurance gains and 5-8% fat loss in 8 weeks.
• Benefits:
  • Endurance boost (50-70%)
  • Fat loss (5-8% body fat)
  • Improved heart health (10-15% HDL increase)
  • No PCT needed (non-hormonal)

• History: Developed by GTx as a stronger Andarine alternative, researched for lean gains.
• Science: Binds receptors (Ki ~1 nM), boosting protein synthesis. Preclinical data shows 2-3 kg lean mass gains and 5-7% fat loss in 8 weeks.
• Benefits:
  • Lean muscle (2-3 kg in 8-12 weeks)
  • Strength gains (15-25%)
  • Fat loss and definition
  • PCT required due to suppression
• Considerations: Stronger suppression than other SARMs. Bloodwork critical.

Can You Stack SARMs? Is It Worth It?

Stacking SARMs—combining multiple compounds—aims to amplify results by targeting different pathways (e.g., muscle growth, fat loss, recovery). It’s common in bodybuilding research, but is it worth it? Let’s explore the benefits, risks, and top APH Science stacks.

Benefits of Stacking SARMs

1. Synergistic Effects: Combining SARMs like RAD-140 (anabolic) with Cardarine (fat loss/endurance) or MK-677 (recovery) hits multiple goals, yielding 4-6 kg muscle gains and 5-10% fat loss in some stacks.
2. Customisation: Stacks can be tailored for bulking, cutting, or recomp, optimising results for specific goals.
3. Enhanced Recovery: Compounds like MK-677 or Ostarine speed recovery, supporting intense training during stacks.
4. Maximised Gains: Stacks like the Mega Bulking Stack combine three compounds for amplified muscle growth (5-7 kg in 8-12 weeks).

Risks and Considerations

• Increased Suppression: Stacking suppressive SARMs (RAD-140, Ligandrol, S23, high-dose Andarine) heightens testosterone suppression, requiring robust PCT like Recharge 2.0.
• Side Effects: Higher doses or multiple compounds may increase risks like vision changes (Andarine), fatigue, or liver strain. Bloodwork is crucial.
• Limited Data: Human studies on stacking are sparse; most evidence is preclinical or anecdotal.
• Cost: Stacking can be pricier, though APH Science stacks offer value.

Top SARM Stacks

1. Bulking Stack (RAD-140 + MK-677)
   • Purpose: Aggressive bulking.
   • Effects: RAD-140 drives 3-4 kg muscle gains and 20-30% strength boosts; MK-677 adds 2-3 kg via GH and recovery. Expect 4-6 kg total gains in 8-12 weeks.
   • Why It Works: RAD-140’s anabolic power pairs with MK-677’s recovery and appetite boost for massive size.
   • PCT: Required due to RAD-140 suppression.
   • Bloodwork: Monitor testosterone, IGF-1, liver enzymes.
2. Alpha Stack (Ligandrol + MK-677)
   • Purpose: Fast muscle growth.
   • Effects: Ligandrol delivers 3-4 kg muscle and 15-25% strength gains; MK-677 enhances recovery and adds 2-3 kg. Total gains: 4-6 kg in 8-12 weeks.
   • Why It Works: Ligandrol’s potency meets MK-677’s GH-driven recovery for rapid, quality gains.
   • PCT: Required due to Ligandrol suppression.
   • Bloodwork: Check testosterone, IGF-1, lipids.
3. Lean Muscle Stack (Cardarine + Ostarine)
   • Purpose: Lean gains and fat loss.
   • Effects: Cardarine cuts 5-8% body fat and boosts endurance by 50-70%; Ostarine adds 1-2 kg lean muscle and preserves mass. Results: 1-2 kg muscle, 5-8% fat loss in 8-12 weeks.
   • Why It Works: Cardarine’s fat-burning and stamina pair with Ostarine’s lean muscle retention for a defined physique.
   • PCT: Not typically needed at low doses.
   • Bloodwork: Monitor lipids, glucose.
4. Mega Bulking Stack (MK-677 + RAD-140 + Andarine S4)
   • Purpose: Maximum bulking and definition.
   • Effects: RAD-140 (3-4 kg muscle, 20-30% strength), MK-677 (2-3 kg, recovery), and Andarine (1-2 kg lean muscle, 5-7% fat loss) combine for 5-7 kg muscle gains and 5-7% fat loss in 8-12 weeks.
   • Why It Works: Triple synergy hits anabolic growth, recovery, and lean definition for colossal results.
   • PCT: Required due to RAD-140 and potential Andarine suppression.
   • Bloodwork: Test testosterone, IGF-1, oestradiol, liver enzymes.

How to Stack SARMs Safely

• Start Low: Use minimum effective doses (e.g., 10 mg RAD-140, 25 mg Andarine) to assess tolerance.
• Cycle Length: Stick to 6-12 weeks, with 4-8 week breaks.
• PCT Planning: Use Recharge 2.0 for suppressive stacks (Bulking, Alpha, Mega Bulking).
• Bloodwork: Test pre-cycle, mid-cycle (4-6 weeks), and post-cycle for testosterone, liver, lipids, and IGF-1. Use LetsGetChecked with code SARMS20 for 20% off.
• Nutrition: High-protein (1.6-2.2 g/kg bodyweight), tailored carbs/fats for bulking or cutting.
• Training: Match stack goals—heavy lifts for bulking, volume/cardio for leaning.

Is Stacking Worth It?

Stacking SARMs can be worth it if you’re aiming for faster, more dramatic results, but it’s not for beginners. The right stack (e.g., Bulking Stack for size, Lean Muscle Stack for definition) can outperform solo compounds, delivering 4-7 kg muscle or 5-10% fat loss in 8-12 weeks. However, increased risks like suppression or side effects demand careful planning, bloodwork, and PCT. For novices, single compounds like Ostarine or Cardarine are safer starting points.
