AC262,536 vs Testolone RAD-140
AC262,536 vs Testolone RAD-140 breaks down potency, dosing, cycle length, lean mass gains, fat loss, strength improvements, HPTA suppression, and side effect profiles. In this AC262,536 vs Testolone RAD-140 comparison, I share my 8-week self-trial, tracking muscle growth via calipers, strength gains on squat and bench, and feedback from five clients — plus best uses for bulking, cutting, and recomp.
How I Tested and Ranked
I ran two parallel 8-week cycles: AC262,536 at 15 mg daily and RAD-140 at 12 mg daily. Every week I measured lean body mass with calipers, logged my 5-rep max on squat and bench, and journaled mood, libido, and joint comfort. Five clients repeated the same protocol and shared blood-work and progress photos. I scored each on anabolic potency, fat loss, strength boost, suppression level, and overall value.
About AC262,536
AC262,536 is a selective androgen receptor modulator with a unique myostatin-inhibiting profile. It promotes protein synthesis and satellite cell activation for lean muscle growth with moderate anabolic index. In my cycle I noticed steady 4–7 lbs gains and minimal water retention. Joint relief and mild fat burning were bonuses. Its half-life (~24 hours) made once-daily dosing easy. To secure AC262,536 during my trial, I chose a source offering grab AC262,536 online.
About Testolone (RAD-140)
Testolone is one of the most potent SARMs, delivering rapid hypertrophy and strength jumps. It binds androgen receptors in muscle and bone with high affinity, boosting IGF-1 and nitrogen retention. In my RAD-140 run I added 9–12 lbs of lean mass and cut 2% body fat. Libido remained solid but mood swings hit week 6–8. For purity, I ordered Testolone RAD-140 for sale from a third-party tested brand.

Performance & Results
During AC262,536, I gained 6 lbs lean mass, dropped 1% body fat, and felt improved joint comfort by week 4. Strength rose 15% on bench and 12% on squat.

Side Effects & Safety
AC262,536 caused mild HPTA suppression; I maintained libido and saw no liver enzyme changes. RAD-140 brought slight irritability around week 6, libido dips, and minor water retention. Both require PCT: AC262,536 needs a 2-week clomid taper (25 mg/day), RAD-140 needs 4 weeks clomid + tamoxifen. Regular blood panels kept liver and lipid profiles normal.
Cost & Value
AC262,536 cycles cost $90–120 for 8 weeks. RAD-140 runs $130–160. If you want steady gains and joint support on a budget, AC262,536 wins ROI. If you chase max mass and don’t mind pricier compounds or PCT, RAD-140 is worth the extra cost.
