Best SARMs Stack for Bulking in 2025: How to Maximize Size, Strength & Recovery

If you’ve been searching for the ultimate way to bulk in 2025, you’re probably hearing more about SARMs stacks. SARMs, or Selective Androgen Receptor Modulators, are becoming a favorite for lifters who want steroid-level muscle gains without all the nasty side effects. But stacking them—using two or more SARMs together—is where things get really interesting.

What Are SARMs and Why Stack Them?

SARMs work by selectively targeting androgen receptors in muscle and bone, promoting growth without the same risks steroids pose to other organs. While one SARM alone can be effective, stacking them can amplify your gains by combining different mechanisms—some improve strength, others promote muscle cell growth or recovery. Stacking lets you maximize size, strength, and recovery all at once.

Top SARMs for Bulking in 2025

• LGD-4033 (Ligandrol): Often called the “king of bulking SARMs,” LGD-4033 is powerful for increasing lean muscle mass and strength quickly.

• RAD 140 (Testolone): Known for rapid muscle growth and fat loss with minimal side effects.

• YK-11: A myostatin inhibitor that supercharges muscle hypertrophy by blocking growth inhibitors in your muscles.

• S23: An advanced bulking agent that’s gaining popularity for lean mass gains and strength improvements.

Best SARMs Stacks for Bulking

• Stack 1: RAD 140 + LGD-4033: This combo is ideal if you want fast, noticeable size and strength increases. RAD 140 builds muscle and burns fat, while LGD-4033 packs on solid lean mass.

• Stack 2: LGD-4033 + YK-11: If you want serious hypertrophy, YK-11’s myostatin inhibition combined with LGD-4033’s bulking power makes an effective pair.

• Stack 3: RAD 140 + S23 + MK-677 (Advanced Stack): For experienced users, adding MK-677 (a growth hormone secretagogue) helps with appetite, recovery, and lean gains, making this a potent bulking cycle.

How to Use SARMs Stacks Safely

Dosage matters a lot. Beginners should start low—RAD 140 around 10 mg/day and LGD-4033 at 5-10 mg/day. Experienced users can increase doses but must monitor side effects carefully. Typical cycles run 6-8 weeks. Most importantly, always follow up with a Post Cycle Therapy (PCT) protocol to restore natural hormone balance.

Diet and Training Tips While Bulking on SARMs

You can’t out-train a poor diet. Aim for a protein intake of 1-1.2 grams per pound of body weight daily, with plenty of carbs to fuel your workouts and healthy fats for hormone health. Focus your training on heavy compound lifts with progressive overload, hitting the gym 4-5 times a week. Recovery is key—get enough sleep and consider supplements like omega-3s and magnesium.

Potential Side Effects and How to Manage Them

SARMs are milder than steroids but can still suppress testosterone and cause mood changes or mild headaches. Liver support supplements and avoiding alcohol can help protect your liver. If you notice side effects, reduce dose or cycle length.

Where to Buy Quality SARMs in 2025

Not all SARMs are created equal. Look for vendors with third-party lab testing and transparent reviews. Avoid suspiciously cheap products—quality matters for your health and results.
