    Great cardio improvement

    Using 20 mg. a [subject] noticed an increase in endurance within days. Taking it 1-2 hours before training, [subject] noticed reps increase by a few during certain sets. Did it help lean out? Don’t know how much [subject] was using a few other dietary aids as well.

    Seems to work. Hard to tell because subject’s endurance is already pretty decent. Will buy again.

    The stamina to lift longer is definitely there. Way more than before the research.

    Wow!!! This is no joke. Have used this for my [research subject] and they will not stop running on the [treadmill]. Again, not for human consumption. It does work.

    Very good for stamina increase. Didn’t really notice any fat loss but could have been due to only having home workouts because of lockdown.

    Definitely noticed the endurance sky rocket. Them last few reps is where the moneys at and this puts you in the bag.

    The test subject is taking this plus Osterine at the same time, both ordered from here. They are taking 1 pill each daily and have been taking it for the last 8 weeks. Their diet is very consistent, They are eating enough protein, and exercising daily and they have not seen any gains or loss in body fat. Energy levels are low, ED has showed up, libido is low. Today is the last day they will be taking either for a single month. Will be ordering PCT hoping to rebound. They will not be going through another round.

    Brutal! Un gran producto. Lo uso a 10mg diarios para el control del colesterol después de un ciclo y va perfecto.

    Llega en 10 días aproximadamente súper bien empaquetado y muy discreto 0 problemas en aduanas.

    An awesome product. My [test subject] received great endurance gains from it. He can really run on that wheel!

    GW-501516 was administered over 7 weeks along with Mk-2866 over 8 weeks. I would purchase GW-501516 again for further research, but I was expecting to witness a more significant change visually to the [Subject]. The [Subject] looks more well rounded and balanced in muscle tone and size, but the expected fat loss wasn’t as dramatic as anticipated. Granted, this could be for a variety of reasons: diet, cardio, etc. Almost immediately however, the [Subject] had significant endurance during exercise. Tasks that would normally deplete the [Subject’s] energy over time, simply didn’t until they did. That is to say, the [Subject] performed very well until the body just needed a break, but fatigue did not appear to be an issue. No side effects from the GW-501516 were observed.

    Have not noticed much improvement. Possibly contributed to ongoing pain in my back that has gone away after use.

    Test subjects took 20mg split into two doses daily. After the fourth week subjects showed significant loss of stomach fat.

    With an ostarine and cardarine cut I wasn’t able to see any more weight loss than I usually see. What I did see was an increase in muscle definition and strength. Will need another cycle and an addition to the stack next time around.

    Joel Cook (verified owner)

    Subject was a little underwhelmed with results but did feel like there was a slight boost in endurance but nothing insane… possibly a 10-15% bump. No notable fat loss results after 30 days. Will continue to test to see if upping the dose will yield more noticeable results.

    [Subject] takes this at 20 mg and it’s the only cardarine tried so I have nothing to compare it to but I think this is strong,pure, and legit. I’m two weeks in and [subject] started feeling it by the second day. I had to order me some more.

    Incredible product. The endurance our lab subject showed was amazing. Cardio was fun to our subject. Never winded. Test subject lost 30lbs in 1 1/2 month of cycle. Will definitely be purchasing again.

    This product is great! I like the dosage it come in. [Subject has] more energy during workouts. [Subject] taking this with the ldg-4 stack. [Subject has] lost fat but haven’t lost weight. Muscle mass has definitely increased which is what is keeping [subject] at the same weight. I am happy to see bottom two abs come in. Sarm tech has good products from all my experience
