    Main effects noticed were increase in lean muscle and decrease in overall weight. Noticed an increase in strength with all main lifts. Also no joint discomfort which has happened on certain supps. Overall great “background” compound to give a little extra edge when following a consistent diet and exercise plan.

    Best for recovery. Research subject feels amazing. Took it coming off of surgery and I truly believe it helped so much with the recovery process as well as the strengthening of all ligaments and tendons. Joints felt amazing. Wondering how great it would feel with prolonged use (longer than 2 weeks). Highly recommend!

    Just into it a week so too early to tell but have to say I like the way you guys operate. I accidentally paid twice and you caught it and refunded me. I downloaded Cash App but seemed like I was doing something wrong so I switched to Zelle and paid that way, only to find out (from you) the cash app DID go through. Thanks for emailing me about it and taking such good care of your customers!!! It was $142 and seriously I NEVER would have even looked twice.

    Low dose on this for about 8 months, basically a permanent injury repair and prevention drug. Knees doing great! Esp at 50!

    Pros: Supplement increased lean muscle mass. Decreased body fat %
    Cons: DECREASED HDL (good cholesterol by about half) and slightly inflamed the liver. Recommend getting blood work prior and after cycle to see the effects.
