    This stuff is crazy potent. Subject has been on 2-cap dose, so bottle last 45 days. Tremendous increase in strength gains. Squats up from 405 to 440 in 3 weeks of use, to give you some numbers.

    Ultimately, the research subject would give RAD-140. 4.5 stars. The subject likes this SARM, however, a side effect @ 1 am & pm dose, with additional dose shortly before training was a significant increase in appetite. This may only be from this specific situation, and other subjects may not experience. From this research, this subject reports good for gains, and general strength, but not great for staying on point with a diet. Will try stacking with another, like LGD in future research projects. Great product overall.

    So far so good. Stacking this with Lgd. Took a few weeks to really see a difference but subject has put on 5 lbs of muscle. Arms definitely have filled out and looking more solid. Will be purchasing Osta or S-4 next to cut down. Great product and superior customer service here.

    Hey guys, my subject felt a slight difference and a little bit of a better pump when stacked with mk677 but nothing major and am a little dissappointed because it seem all the other people have such great reccomendations for these two sarms… idk if im doing it wrong because of all the other highly recommended reviews but i dont know. I was expecting alot more of a difference, on my 5th week now and waiting to see if my subject will hit a spurt of something… I read on a sarms website that 10-20mg a day of each is the norm so i stacked one of each daily with breakfast. if anyone has a better regiment please comment on this review. The company as a whole was good though, fast shipping, a definite good service. Thanks alot

    Rad-140 mimics test at 30mg a day. Subject has been on for 5 weeks and reports feeling stronger and hard, and can’t wait to continue to see gains.

    Incredibly strong. Damn impressed with this company, from initial ordering to speed of delivery to end results – 5-wk cycle. Only critique is it took several weekly visits here to finally see them in stock and order. Glad you started doing the pre-order selling but … if you keep running out, maybe keep a larger stock on hand? Anyway, keep it up guys!

    Subject is 50 years old, and still considers himself a “gym rat.” However, age, injuries, and worn joints are beginning to take their toll.

    Began research with this specific product because of its reviews, supposed potency, usages per container, and price (much cheaper and more pills per container than enhanced athlete).

    Study dosage was three pills first thing in the mornings. Without really using the weight needed to gain strength, used lighter weights focusing on quality of reps… subject’s strength actually increased. Subject lost body fat. Subject’s muscles felt and looked full.

    Also, unlike enhanced athlete delivering my order two or three weeks later, my order arrived within a day or two after the order was completed.

    From the ordering process, the delivery of the product, and the quality of the product itself, I am very pleased with SARMTECH.

    Will be ordering this product, along with others, again…

    Stronger than TRT at 2 caps per day. GREAT strength increases. Vastly improved recovery times. Only side is increased aggression. Will be buying monthly because unfortunately, this is probably too effective to remain legal for long. Stock up now! RAD140 is almost too legit!

    Fast awesome shipping, Great gains, Great price. Stacked rad140 (15mg), mk677 (15mg), LGD4033 (10mg) and MK2866 (15mg) and very pleased with experiment results so far! Only 2 weeks in and subject is breaking major records. Will start S4 in week 5 @ (25mg twice daily) and up rad140 dose to (30mg). Will definitely do a PCT along with GW501516.

    I am only leaving a 4 at this time because I am just finishing week two of my subject’s research cycle. So far so good. Stacking this and MK-2866, both at 15mg or 1 pill each. I can definitely notice a difference in subject’s muscle endurance and some strength. I look forward to seeing where this goes. Looking to up the dosage in week 3 to 30mg or two tabs each.

    Test subject showed the following: increase in muscle hardness and fullness, increase in appetite, increase in strength, more focus during strenuous activity, decrease in body fat and decrease in natural test. This is a very strong potent product. Recommend pct for your test subject post experiment. Sarmtech.net couldn’t get anymore legit. Good job guys

    Just finished 6 weeks study. It’s crazy powerful. 1 capsule is enough! 2 gave subject a headache and after researching 1 RAD140 is enough at 15mg. Still have half the bottle left which is great so plan is 6wk off-cycle break in research, then 6wk back on with remainder.

    Great gains, great price. Stacked rad (1 per day) with mk677 (1 per day) and very pleased with experiment results so far ; ) about 5 wks in. Subject reported somewhat of a headache or flush feeling head and face the first week or so starting the rad, which lasted 2-3 hours, but that went away after acclimation. Solid company, impressed.

    I was very pleased with this experiment 🙂 My subject killed it at the gym this month and bulked up 4-5% outgrew his t-shirts in about 3 weeks! Would give it 5 stars but reserve that for lgd4033, which gave same results without as much water gain!
