Best SARMs for Bulking 2025 (Expert Guide + Real Results)

If you’re looking to pack on serious size in 2025 without diving headfirst into full-blown anabolic steroids, SARMs are still holding their ground as the go-to tool for enhanced lifters. But with more options on the market than ever before—and even more misinformation online—knowing which SARMs are best for bulking is key if you want real gains without wrecking your hormone panel.

In this guide, we break down the top 5 SARMs for mass in 2025 based on growth potential, suppression risk, half-life, and real-world results.

📊 Top SARMs for Bulking in 2025

SARM Muscle Gain Suppression Half-Life Water Retention Notes
RAD-140 🌟🌟🌟🌟 High 16–20 hrs Low Strong dry gains
YK-11 🌟🌟🌟🌟🌟 Very High ~6–10 hrs Moderate Myostatin inhibitor
LGD-4033 🌟🌟🌟🌟 Moderate 24–36 hrs Mild Excellent for size
S23 🌟🌟🌟 Very High ~12 hrs Mild Strong but suppressive
MK-677 (oral) 🌟🌟🌟 None 24 hrs High GH secretagogue

🏆 1. RAD-140 (Testolone)

Best for: Clean, dry size with minimal water bloat

RAD-140 has held its crown for years because it delivers size without puffiness. It’s one of the strongest mass-building SARMs on paper and in the gym, with many users reporting 5–10 lbs of lean mass in 8 weeks.

  • Dose: 10–20mg/day

  • Cycle length: 8–12 weeks

  • Stack suggestion: RAD-140 + MK-677 or LGD-4033

  • Suppression: Moderate to high; PCT recommended

“RAD feels like test-lite. Great pumps, solid strength, no moon face.”

⚔️ 2. YK-11

Best for: Breaking plateaus and dry mass gains

Technically a SARM-like myostatin inhibitor, YK-11 ramps up follistatin production, potentially unlocking growth your genetics capped. It also acts as a partial androgen, so it delivers similar aggression and fullness as mild gear.

  • Dose: 5–10mg/day

  • Cycle: 6–8 weeks max

  • Stack suggestion: YK-11 + RAD-140 or LGD-4033 (aggressive)

  • Suppression: High — PCT mandatory

“YK-11 is for experienced lifters only. Think dry, vascular, explosive.”

🏋️ 3. LGD-4033 (Ligandrol)

Best for: Size and strength in first-time users

This is the most well-studied SARM to date. LGD-4033 puts on size fast — often with a mild strength boost and smoother recovery. Expect more water weight than RAD or YK, but also more scale movement.

  • Dose: 5–10mg/day

  • Cycle: 8 weeks

  • Stack suggestion: LGD-4033 + MK-677 (classic bulk)

  • Suppression: Moderate

“This is the one I recommend to guys on their first run. It delivers.”

🔥 4. S23

Best for: Hardcore size and hardening

S23 is potent. It’s more suppressive than most SARMs and has a strong binding affinity to androgen receptors. Great for cutting or lean bulking phases, but not beginner-friendly. It can harden physique and increase aggression in the gym.

  • Dose: 10mg/day (split into 2 doses)

  • Cycle: 6 weeks max

  • Stack suggestion: S23 + RAD-140

  • Suppression: Very high — must have PCT

“Big pumps, crazy aggression. Not for the faint of heart.”

🩸 5. MK-677 (Ibutamoren)

Best for: Growth hormone boost, appetite, sleep

Not a true SARM, but MK-677 makes this list because it helps create the perfect growth environment. It stimulates GH release, improves REM sleep, and cranks up hunger. Use solo or stack for synergy.

  • Dose: 10–25mg/day

  • Cycle: 12–16 weeks

  • Stack suggestion: MK-677 + RAD-140 or LGD-4033

  • Suppression: None (but can elevate prolactin & blood sugar)

“MK-677 = hunger, recovery, size. Just be ready to eat.”

📊 Stacking for Mass: Sample Protocol

12-week Advanced Mass Stack:

  • RAD-140 (10mg/day)

  • LGD-4033 (5mg/day)

  • MK-677 (15mg/day)

Support:

  • Fish oil, citrus bergamot, NAC (liver, lipids)

  • Enclomiphene or Nolva (PCT after)
