    [Subject] Did a month a half cycle and really noticed results in that last 2-3 weeks push. Was a great feeling, no lag effects and no side effects. Probably my favorite product on this site hands down.

    Great product, Saw great strength increases in week 4-6 max Bench went from 275-300lbs. Muscles got larger. Did not eat clean. If you want to get ripped, you must be in a deficit. PCT is a must but strength and size stays. No sides, some suppression

    The results of these studies are very promising. With RAD140 [research subject] lean body mass increased sharply during the study, and this increase in lean quality was dose-dependent, so as the dose increased, the loss of lean body mass and fat became more obvious. Therefore, RAD140 is a true SARM with all the properties expected from this compound-(safety and effectiveness).

    Done a 6 week cycle then done pct. Strength gains were absolutely amazing, didnt notice any physical changes as [subject] was 20% bf and still bulking. Going to try stack rad with a test base as think this would work amazing. Dont expect to look like your on roids on SARMS ONLY they are sarms not steroids even tho RAD is the strongest one from my experince.

    Shelbert Creech (verified owner)

    Test subject started with a different SARM company 10 weeks ago and used that company for the first month of the cycle of RAD-140 and GW-501516 with very little results.

    Test subject switched to SARMTech nine weeks ago and the gains went trough the roof and physique tightened up nicely. At 48 years old, test subject’s abs are peaking and dropping fat and is more vascular. Test subject will use another two weeks before switching to MK-677, FreeUp Test Booster and Andro AI Estrogen Blocker as a four week PCP before the Test Subject goes back on the RAD-140 and SW-501516. Test subject will most likely stay on a low dose of MK-677 during next cycle.

    The subject experienced noticeable size and strength gains. However, mild testosterone suppression is also noticeable with longer-term usage. Side-effects may vary by subject.

    Rapid strength and size gains, though [subject’s] test levels and libido were suppressed. [Subject] stopped after 4 weeks and levels returned. Will run another mini cycle at some point.

    Arthur Walter (verified owner)

    subject has been taking for three weeks but is not sure if results are placebo or really the effects, taking 15 mg daily and lifts have not increased yet but [subject does] feel a little bit leaner and has gained some weight
