Im sure a lot of guys will hammer me for this, but over the last couple years I have used a lot of sarms from a reputable sponsor here. Mk-677, Rad-140 most recently,caber (not a sarm I know), TB-500, Gw, and a few more. My results...not really anything at best. I recently did 8 weeks, 2 bottles of rad-140, 1ml per day. In the first few weeks i was irritable and gained like 8 lbs. No difference in muscle size, so I am not sure if it was water or what. Honestly, I saw NO difference using any of the sarms in size or strength. 2 weeks after the rad, all 8lbs is gone. Now, guys will ask my diet, I am 59, 211lbs. I am on roughly 3800 calories a day, fairly clean.yesterday, according to my fitness app I had 355 grams of protein,354 grams of carbs and a total of 3,802 calories. Now with the MK, i did see SOME effect, a little vascularity develop, and then I was cutting, and it seemed to help, and i have used products from different "reputable" companies, tb-55 seemed to heal, the caber was fun for sex, until it was about 2 weeks old, then it lost potency and had to be updosed, I have used the Tada for prostate health, and for sex with success. I am not saying the products are bunk, but, I think there is enough ingredients in so you feel something, but IMO they are not worth the cost. NOW, i am on HRT, so, in fairness i am not sure if that is why rad-140 didnt work, however just putting this out for guys spending hard earned cash on stuff expecting results. It just seems odd to me nobody questions like, say, why ALL peptides are a white powder in the bottom of a vial, cjc looks like tb,and IGF1, with the labels off they all look the same...how do you know? they all dissolve the same in bac H20...how is that even possible? Not trashing anyone here, just giving honest review of stuff i have tried. take it for what you want.
