SR9009 vs Testolone RAD-140
In this SR9009 vs Testolone RAD-140 breakdown you’ll see endurance, fat loss, lean mass, strength, dosing, cycle length, safety profile, pros & cons, and cost side by side. I ran two 6-week cycles—SR9009 for energy and metabolism, RAD-140 for raw muscle and power—logged my data, gathered client feedback, and ranked each SARM for cutting, bulking, and recomp. Read SR9009 vs Testolone RAD-140 to find your perfect fit.
How I Tested and Ranked
I conducted back-to-back 6-week cycles on myself and five clients. For SR9009, we dosed 30 mg split twice daily; for RAD-140, 15 mg once daily. I tracked run times, VO₂ max (via a simple treadmill test), body-fat caliper readings, 5-rep max on squat/bench, sleep quality, mood, and appetite. Clients logged energy levels and recovery. I scored each SARM on endurance, fat oxidation, lean gains, strength, safety, and price.
About SR9009 (Stenabolic)
SR9009 is a Rev-Erbα agonist, not a true SARM, but it’s grouped with them for its performance boost. It ramps up mitochondrial activity, boosts circadian rhythm, and increases basal metabolic rate. Users report better cardio, faster recovery, and mild fat loss. It’s non-hormonal, so no HPTA suppression. I tested SR9009’s effect on my morning jogs, cutting 30 seconds off my mile and dropping 1.5% body fat over six weeks. Grab SR9009 here for stamina and metabolism.
About Testolone (RAD-140)
Testolone is a potent androgen receptor ligand that mimics testosterone’s effects on muscle and bone. It drives strong protein synthesis and nitrogen retention. In my RAD-140 cycle, I gained 9 lbs of lean mass, upped bench by 20 lbs, and felt a solid strength surge. It does suppress natural testosterone, so PCT is essential. My clients loved the quick bulk and power but noted slight mood dips. Shop Testolone RAD-140 for serious muscle and strength.

Pros & Cons
SR9009
- Pros: Non-hormonal, zero suppression, boosts endurance, improves recovery, supports fat oxidation.
- Cons: Short half-life (requires split dosing), can disrupt sleep, minimal mass gain.
- Best For: Cutting, cardio phases, early morning energy spike.
Testolone RAD-140
- Pros: Rapid lean muscle growth, major strength increases, moderate fat loss.
- Cons: Suppresses natural testosterone, mood swings, needs solid PCT.
- Best For: Bulking cycles, strength-focused protocols.
Performance & Results
On SR9009 I shaved 30 sec off my mile, cut 1.5% body fat, and felt less soreness after leg day. With RAD-140 I added 9 lbs lean mass, upped my bench by 20 lbs and squat by 25 lbs, and saw visible muscle fullness. Clients mirrored these outcomes: SR9009 for energy and cut phases, RAD-140 for serious size and power.
Side Effects & Safety
SR9009 users report mild insomnia if dosed late; I switched to morning/afternoon split to avoid sleep issues. No liver strain or hormone suppression occurred. RAD-140 brought slight irritability and libido dips during week 4–6; bloodwork showed testosterone suppression, so I ran clomid 25 mg/day for 3 weeks PCT.
Cost & Value
A 6-week SR9009 supply runs $80–100. RAD-140 costs $120–160 for 8 weeks, prorated to 6 weeks. If your aim is fat loss and endurance, SR9009 delivers more bang per buck. For maximum muscle and strength, RAD-140’s extra cost pays off.
My Personal Ranking
- Endurance & Cut: SR9009—zero suppression, energy boost.
- Balanced Recomp: Pair SR9009 early, then RAD-140 mid-cycle.
- Mass & Power: RAD-140—dominant anabolic effect.
FAQs
What is SR9009?
A synthetic Rev-Erbα agonist that boosts mitochondrial function, endurance, and fat oxidation without hormonal suppression.
What is RAD-140?
A potent SARM that binds androgen receptors in muscle and bone, driving strong lean mass gains and strength increases.
Can I stack SR9009 and RAD-140?
Yes. Many start with SR9009 for cut and endurance, then add RAD-140 around week 3–4 for hypertrophy.
Do I need PCT with SR9009?
No. SR9009 doesn’t suppress HPTA, so post-cycle therapy isn’t required.
How long should my cycle be?
SR9009: 4–8 weeks. RAD-140: 8–12 weeks, with PCT afterward.
Which SARM is better for cutting?
SR9009 excels at fat loss and energy. RAD-140 helps retain muscle but is secondary for cutting.
Which SARM is better for bulking?
RAD-140 wins for lean mass and strength. SR9009 adds minimal size.
