    After my reserch subject has been reaserching with sarms for few years (all of them exept andarine), prohormones, and steroids, here are the conclusions.
    1. Sarmtech are the best. End of discussion.
    2. Sarms are as strong as prohormones. When training natural, rs reached his full natural potential. For example, biceps 16 inch. No matter how much he traind, eat and sleep. 16. After prohormenes, and sarms cycels (3 cycels), 18 inch. And rs is a small guy, only 5,7 height. But here is the thing, the cycels after, no matter how much rs traind eat etc, and increased the sarms dose (maximum stack was 30 rad, 10 lgd, 15 ostarine, 10 yk), stayed 18. Tried to stack prohormones andro1 andro4, decabolin (from hightech pharmaceuticals), still 18 inch biceps, only gaind fat from that cycel. Only methyked steroids like methylstenobolone, got rs bigger. But he was affraid continue them for long. But i think sarms are stronger, because they got rs to 18 inch (after it was a dit down off cycel) faster than ph. And also, no side affects at all using sarms, even at super stacking them. No shutdown at all. Rs Was using sarmtech freeup for post cycel but didnt feel he needed. But the ph were a whole different story, strong shutdown, back pumps, he lost appetite, and got severe back acne. So i guess rs is not gonna reaserch with ph as long sarmtech exists. And to end this topic, i think u can conclude from that why some people are not affected by sarms- they might be using steroids and cant get bigger by sarms, or even cant maintain the muscle mass that was built by steroids, using sarms. I honestly thing that there is no chance that a natural kinda guy wont gain from sarmtech sarms. It cant be so strong to one, and do nothing to other. Adding 2 inches to byceps, and being able to lift double weight on the bench, after being stuck for 2 years, is definitely not placebo. (And of course bad nutrition and wrong training might be the reason for no results, were talking on people who know these principles).
    3. Every sarm at his maximum dose is good enogh to not loose even a gram during cut, and also made rs stronger during the cut. But never gaind muscle during cut using sarms, even when stacking them at maximum recommended dose ( rs maximum during cut was, rad 140 30, lgd 10, yk 15). So i conclude that stacking them was a waste of money, couse for example using lgd alone (1 sarmtech pill) gave the same result (maintain muscle) . Only using steroids, got rs to gain some muscle during a cut.
    3. Which sarm is the best? For rs definitely rad 140. Got rs so strong, even during major cut. It was unbelievable. And fast acting too. Behined it, lgd, s- 23. Also lot of force and fast acting. But still considerable diffrence on the force part from rad. Ostarine behined them.
    4. Cardarine and stenabolic will give u excellent energy during a cut. But dont expect boom effect like ephedrine, but more balanced energy during the day, even at major cut. Which is much better than ephedrine. Ephedrine make u feel like an heart attack is coming, make u shake and feel affraid. U dont know from what, just affraid. Never gonna let rs using it after discovering sarmtech cardarine and stenabolic. To choose onw, it realy depend on what u need, if u looking for more boost, go for stenabolic. If u want to be more balanced, go for cardarine. And by the way, neither of them or ephedrine will make u slimmer unless u have the right diet.
    5. All these diffrent (good) results from sarms, only from sarmtech. Other brands got rs a bit bigger but not too much diffrence between them. Which make rs wonder what they are. For example, When rs found sarmtech, he than understood what is the “rad140 makes u a lot stronger” people were talking about.
    Please consider carefully what i wrote, ive waited a long time with it so i can write honest conclusions from my long reaserch.
    Hope sarmtech will stay forever.

    Product performed to expectation for test subject. 12 lb gain in 45 days, with gains not added from fat loss in the equation since no fat composite test was administered. However visual evidence of fat loss was evident.

    While the gyms where still closed I decided to have my subject jump on a cycle of Rad-140 and managed to put size and muscle mass @15mg a day, training with just the essential barbell and doing compound lifts. Went from 165 – 182lbs in 2 months.Great Stuff

    Really shocked (delighted) with the results. I think this is the first time ever my research subject has stacked on muscle. Was a bit suppressive though so a PCT would be a good idea.

    Amazing results even after just 2 weeks of testing. Stacked with mk-677 and ostarine really woke up my receptors. Strength is a steady increase every gym session. Packed on 12lbs already some from non clean eating in the beginning.
