    [Subject] Just finished an 8 week cycle on rad-140 and ostarine. Shipping time is pretty good usually all things considered. For the product, ill be honest, [subject] did start putting on more muscle in less time while also being in a cutting state. Excited to try these with yk-11 during my bulk. No side effects for [subject] (thankfully) and [subject] finally beat 2 plates for 10 reps goal. Strength went up for sure.

    Strong product. My only dislike is the only option being taking it at 15 or 30 mg. [Subject] two weeks in and really starting to feel it though. [Subject reports] everything feels lighter and lighter in the gym by the day.

    Cannot believe the results. Subject had taken a month off dealing with a shoulder impingement. After 8 weeks not only gained all strength back, BUT set a couple PRs. Cannot wait for next trial run, now that subject is back to full strength!

    During this cycle the test patient noticed increased strength in all areas along with adding great weight in the right areas. The studies were very successful and would recommend to other studies if wanting to grow in strength and size

    Test subject is on 3rd round of testing. Has shown excellent results in less than 3 weeks. About purchase supply for a 4th round of testing after a break

    Jonathan Ludlow (verified owner)

    Ordered from a few different sources in the past with varying results but I can definitely confirm that SARMTECH is hands down the best value for money when it comes to price per mg.

    Strength and size gains in lab [subject] were apparent after just over a week and, although mass increase is more subtle then with LGD, it is a very ‘dry’ gain meaning I could up my lab [subject’s] calorie intake with virtually no fat gain.

    Will definitely order again but, because of the great value for money, one bottle lasts two stacked cycles.

    Kevin Shuman (verified owner)

    Very good results. I did see a noticeable increase in both strength and weight. [Subject] started with 2 caps per day for 2 weeks then titration down to QD for the duration. No real side effects noticed and no surprises, which was great. I would recommend both the product as well as the Sarmtech team. Very helpful and user friendly.

    Joseph Miles (verified owner)

    Been [researching] this for a month now on 3 month cycle, [subject] taking 2 caps of Rad140, and 2 caps of MK677 in morning and at night. Using a Test booster daily as well. Before the gym, [subject] takes 2 NO2 pump and 1 Higamine with some preworkout and can lift heavier. And I have noticed extreme muscle growth as well. [Subject] used to be able to only stay in the gym about an hour, now can last up to 2 hours and roughly 30 minutes. These products are excellent, great for bulking. Next cycle I will stack LDG4 and YK11 with these and see what the results will bring. Only downside I saw is increased agression, but its manageable.

    Rad140 has definitely been effective in my experience and after ordering a couple times, I decided I should leave a review. The product is legit, and sarmtech ships products to you quickly and discreetly. So far I believe sarmtech to be a reliable source for sarms and will continue to order from this website if continuing to [research with] sarms.

    This product worked so well that testing was stopped after 4 weeks, as the results were far better than expected.
