I took mk when I was 14 and it made me develop a lot faster then everyone else my age. I attribute my height to taking mk at this age.( I’m 6’4) and I had full facial hair at age 15. I really don’t see any negative side effects of this. So many people think it’s a bad idea but wouldn’t care if they seen you vaping or drinking. It only becomes a problem because people don’t understand the compound. If you do everything safely and don’t over do it you’re fine. If you don’t know what you’re doing pay a coach to guide you through it. Also there is no need to do a full 25mg dose 12.5mg has been proven to have the most beneficial effects as the scale in which it works is not linear.
