Started at 5mg a year back. Always stayed athletic, but once I hit my 60s the weight just started piling on regardless. Kicked off at 252 pounds, and a year later I'm back at my college weight, training like I'm in my thirties again. 67 years old now, sitting around 180-185 with a 34 inch waist, feel fantastic. Mounjaro really has been a miracle for me.
