    Good energy from this was experience by the test subject. During the first bulking cycle they gained 20lbs. Adding this to the second cycle the test subject only gained 7 but there was very little fat tissue gain. Much more dense muscle mass. Test subject used at 20 mg per day. Ability to work out longer with out fatigue was noticed as well.

    GW-501516 run the extra mile … literally. Bottom line is this stuff works. Return customer as Sarmtech is simply the best. Great products that work, packaging to suit “circumstances” with international shipping, and support responded to my queries in good time. I’m a return customer because this product works like a dream!

    [Subject] use 1 pill 45min-1hr prior to doing cardio or jiu jitsu, and there is a NOTED difference in performance. [Subject] will still get “winded”, but bounce back, and am able to go more rounds or run further when taking cardarine.

    I’ve used SARMTECH pretty regularly and have yet to run into anything that felt bunk. They’re always on top of their game with shipping times and I’ve had great results all around. Cardarine is easy to tell if it’s legit, and this one definitely hit SUPER fast, amazing cardio helper here.

    This is incredible, especially combined with Rad 140. [Subject] started out at 193 around 15% body fat. [Has] been lifting for around a year and 8 months before starting cycle. Now 9 weeks in on the Rad 140 and 5 weeks in on Cardarine. [Subject] now 205 around 11% body fat. Diet was decent but [] go over [] calories for the day and eat pizza some what regularly and still cutting like crazy. It is a cheat code.

    [Subject’s] endurance immediately went up drastically. [Subject] never get tired cardiovascular wise. It allows [subject] to workout for way longer, get the extra 2 reps [subject] couldn’t get before, [subject’s] recovery time is off the charts, [subject] does 2 a days with ease, highly recommend Cardarine. The perfect stack in my opinion is Cardarine and Rad 140, the rad will help you [subject] get jacked, WAY stronger and build muscle while cardarine will up your endurance through the roof, help preserve muscle even in a calorie deficiency and cut fat like crazy.

    Remarkable changes in body composition and improvement in athletic performance! Subject completed course of research over 18 weeks. Training emphasized mobility, calisthenics, and movement athletics, with additional endurance/HIIT training. For initial six weeks, subject was administered 15mg of Ostarine and 10 or 20 mg of Cardarine daily. For subsequent six weeks, subject underwent post-cycle therapy with natural testosterone booster and 50 mg estrogen blocker daily. For final six weeks, subject administered same Ostarine/Cardarine regimen.

    Observable gains in lean muscle mass and noticeable decreases in body fat. Strength performance improved at accelerated pace over 18-weeks, versus baseline.

    Subject reported feelings of increased cardio endurance and strong, sustained increases in sexual libido. 🙂

    Test subject was started on 10mg 2 weeks ago and all indications show an increase in cardio and slight fat burning with diet/training remaining consistent from baseline. Will continue to monitor and log results but at this point its meeting expectations.

    Ben Cance (verified owner)

    Have tested product for four days, minor increases in energy level at 20mg e.d., potential increases to stamina during endurance activities.. have not isolated product to test individually so it’s hard to tell if this product is 100% effective.

    Spencer Bass (verified owner)

    Started the subject on this after coming off of a rad stack and when taking a pct the subject retained most gains through the first few weeks and then started progressing forward again shortly thereafter. The subject’s diet was also not optimal yet minimal fat gain was experienced. Seemed to do its job pretty well.
