    I’m on my fourth [research] over the past couple years .
    week number two [subject] takeing 30 mg, 15 a.m. 15 in the p.m. that seems to help with the hunger. Back to working out seven days a week all lifts have increased has not affected sleep any seems to be working well.

    Marcus Waugh (verified owner)

    MK-677 in combination with RAD-140 and you have a mixture for growth. MK-677 had the subject healing in 1-2 days instead of 2-3. 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!

    I have continued on another cycle with MK-677 and the research has been consistent with both strength and lean muscle gain. My research included a stack with RAD-140. My research has shown that usage of this combination has resulted in efficient lean muscle and size gains. Personal experience can vary, but I would recommend trying this stack.

    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. MK677 is amazing for maintaining during an off-anabolics phase.

    So far subject loves this product. Great sleep improvement as subject researches it at night and falls asleep fast and wakes up refreshed without fail.

    Robert Scott (verified owner)

    This was [subject’s] first time taking mk 677. It took awhile to kick in, about a week or two. Definitely, different from sarms or steroids, that only takes a few days to kick in. mk 677 definitely helped [subject] recover quick. Workouts were pretty intensive too, it consists of full body weighted calisthenics and in about 2-3 days, most of soreness was completely gone. Never got any strong appetite effects like how other people was saying, [subject] ate normal. I will definitely buy mk 677 again, but this time with a higher dosage. [Subject] dosage was only 15 mg a day. While [subject] did have more energy throughout the day, [subject] didn’t have that much of a strength increase, and maybe it’s because of low dosage. Could also be the reason why [subject] didn’t get big appetite effects either.

    I give subject 1 dose a night before bed. Really helps knock them out and increases sleep/recovery.

    Justin P (verified owner)

    Stacked with Ostarine. Noticed hair & nail growth, possible increased acne, and increased hunger, so it seems to be working. Will continue after Ostarine cycle during PCT and probably into LGD cycle. Seems like a legit buy so far!

  22. 5 out of 5

    Michael Alley (verified owner)

    Worked AMAZING! Stacked with the Rad140, 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!

    I have taken my fair share of different orals from multiple companies, ive also put on decent size from those brands, but this one takes the cake. No side effects first cycle and put on 34lbs now on the 2nd and so far so good should hit 50lbs gained total. Never have I ever experienced an oral so effective and with no side effects. Stacking with Rad is the perfect mix.

    Haven’t noticed much change in hunger, maybe a little bit more intense but not by much.

    awesome addition to the stack, helped me wat more which i struggled with normally

  37. 5 out of 5

    Steve Steele (verified owner)

    Seems pretty great. Subject’s first round with this compound immediately (approx. 30-45 minutes of ingestion) yielded the hunger pangs associated with ghrelin mimetics, which is a great sign that the product is 100% real. By day 2, subject’s skin and hair felt as though more natural oils were being produced. Another sign that the product is legit. Finally, sleep was deep and refreshing considering the subject has had a very hard time sleeping straight through the night for many years now.
    Regarding performance and recovery. Intermediate weightlifting subject has been seeing steady Rep and/or loading gains for his most previous Meso-cycle. Nothing crazy. Just the ability to reach failure and beat that number from last week (most exercises this meso performed in 15-20 rep range).
    Here’s the big takeaway.
    One performance day, subject injured himself while pushing to failure on bent rows. Lower right quadrant, L-spine muscle or possibly disc injury. Pushed through workout.
    Recovery with MK677 is insanity.
    Within 48 hours, subject had ZERO pain in the area that would normally have taken a weekend more to completely go away with OTC ibuprofen/anti inflammatory meds.
    Overall. An amazing compound and dosage this first cycle was restricted to 1 – 15mg dosage per day/ 90 days.
    Subject consumed 1500 calories whilst in a deficit (sometimes cheats to 1650-1700). Over 90 days, weight fluctuated ONLY 3-5 lbs up and down, while Body fat % seems to have dropped at least 1-3 % !!!
    Also, Sarmtech staff is EXTREMELY reliable and helpful. Shipping immediately upon receipt of my payment.
