RAD 140 vs LGD 4033: The Battle for the Ultimate Muscle-Building SARM
- by Brian Duclos
Everyone wants the fastest route to lean, hard muscle without the crash that comes from traditional steroids. Two compounds dominate that conversation: RAD 140 (Testolone) and LGD 4033 (Ligandrol). Both promise massive gains, improved recovery, and clean muscle retention — but which actually delivers?
In this breakdown, we’ll cut through the hype and look at what research and real users actually show when comparing RAD 140 vs LGD 4033. You’ll learn how each works, what the side-effect profiles really look like, and how to stack or cycle them safely for serious results.
RAD 140 (Testolone)
Mechanism: Highly selective androgen receptor modulator that binds aggressively to muscle tissue receptors with a stronger anabolic-to-androgenic ratio than testosterone — roughly 90:1 [1].
Effects: Stimulates lean muscle growth, boosts protein synthesis, and increases strength without the same prostate or hair-loss risk tied to anabolic steroids.
Bonus: Early animal data shows potential neuroprotective effects [2].
LGD 4033 (Ligandrol)
Mechanism: Selectively targets skeletal-muscle androgen receptors, enhancing nitrogen retention and muscle protein synthesis [3].
Effects: Yields steady lean-mass increases and strength gains, often with less aggression and smoother recovery compared to RAD 140.
Clinical Data: In a 21-day trial, subjects gained up to 1.2 kg of lean body mass with minimal side effects [3].
Bottom line: RAD 140 hits harder and faster. LGD 4033 is steadier, more forgiving, and ideal for first-timers.
Across fitness communities, here’s the consensus:
RAD 140: Delivers explosive strength increases and fuller muscle density within 2–3 weeks. Users often notice shoulder and arm hypertrophy first. However, suppression of natural testosterone is stronger, especially beyond 8 weeks.
LGD 4033: Produces smoother, more gradual gains — typically 5–8 lbs of lean mass per cycle — with milder suppression and fewer mood swings. Appetite and endurance often improve noticeably.
Common Stacks:
RAD 140 + MK-677 = Maximum anabolic drive and recovery.
LGD 4033 + Cardarine (GW-501516) = Lean bulk or recomposition stack with better stamina.
| Compound | Typical Daily Dose | Cycle Length | PCT Needed? |
|---|---|---|---|
| RAD 140 | 10–20 mg/day | 8–10 weeks | Yes – full PCT (Nolva or Clomid) |
| LGD 4033 | 5–10 mg/day | 8 weeks | Mild PCT (Nolva optional) |
Pro tips:
Start low to gauge response — strength will tell you if it’s working.
Run bloodwork before and after every cycle.
Avoid stacking two strong suppressive SARMs (like RAD 140 + S-23).
Follow each cycle with at least a 6–8 week break.

You can’t out-SARM bad nutrition or sleep. To actually grow:
Protein: 1 g per lb of body weight.
Sleep: 7–9 hours minimum.
Training: Focus on progressive overload and compound lifts.
Support Stack: Add liver support (TUDCA or NAC), omega-3s, magnesium, and vitamin D3.

1. Can I run RAD 140 and LGD 4033 together?
Yes, but it’s an advanced move. Expect amplified results — and suppression. Always follow with a full PCT.
2. Which SARM builds more size?
RAD 140. It’s more anabolic, more aggressive. LGD 4033 builds slower but maintains muscle beautifully post-cycle.
3. Can women use these SARMs?
LGD 4033 at micro-doses (2–5 mg) is generally better tolerated. RAD 140 can cause virilization effects if abused.
4. Are these legal?
They’re legal to buy for research purposes in most regions, not approved for human use. Always verify your local laws.
5. How fast do results appear?
Strength and muscle fullness usually spike within 2–3 weeks for RAD 140, 4–5 weeks for LGD 4033.
