    Bret McGaughey (verified owner)

    Test subject gained 8% body weight on 30mg daily for 8 weeks. Then results seemed mostly muscular with little gained fat. Minimal side effects other than being a little lethargic at times.

    Product was amazing . [Subject] Did a full 6 week cycle on it. All good changes. Felt stronger. Started at 158 and ended at 176lbs. Stuff works magic! Keep up the good work SARMTECH!

    The increase of strength that [subject] got from RAD-140 is crazy! On all lifts the weight increased immensely. Bench, squat, and deadlift all got new PRs. Recommend.

    [Subject] on week 8 of Rad 140. [Subject] started off with the MK677 and Ostarine stack. [Subject] didn’t like how it felt on them and mk677 makes – ate like a monster. I highly recommend it for [subjects] wanting to bulk. [Subject] got off MK677 and Ostarine 2 weeks into cycle and switched to Cardarine. [Subject] started out at 195lbs about 14-15% body fat. [Subject] now around 203-204 and 11-12% body fat. Doesnt sound crazy but the leaner you get the harder it is to lose body fat percentages. from 30-15 you just have to stop eating donuts and go to the gym regularly. 15 – 10, you are doing cardio regularly + Hiit weight lifting, eating clean, taking supplements, tracking macro, etc.. [Subject] was sick for a week and a half on the cycle, it gave the motivation to still make it to the gym and still hit PR EVERY workout session. About week 6 1/2 [subject] went from 15mgs of Rad to 22.5 roughly (I cut the pill in half) plus added an extra 5 mgs of cardarine for a total of 15. The vascularity is through the roof, workout twice a day easily, an animal!

    **Down sides** [Subject] feels tired often, it takes a lot of mental focus to force myself to workout, libido has gone down slightly, more emotional as of lately. Small price to pay imo opinion.. Doing the Estrogen supression and natural t booster through Sarmtech and will be on Cardarine for 4 weeks of my PCT care to help with intensity and to stop body from building up fat. Hopefully by 4 weeks test will be back to normal

    Worked AMAZING! Stacked with the MK667, unbeatable results. Have recommended to many many many test subjects and have watched the test subjects increase at least 10-15lbs of lean muscle in 8 weeks! Hands down one of the best products around!

    Subject is showing great results … improved strength at a steady rate.

  11. 5 out of 5

    Mark Hazzard (verified owner)

    Subject had significant strength and size increase. I would compare it close to D-Bol, without all the sides. Stacked it with Cardarine for increased endurance and staying lean.

    [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.

    Kenneth Swope (verified owner)

    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.

    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.

    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.

    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
