I used it for my shoulder. Went through 2 bottles 10mg bottles of BPC. Was using up to 750mcg every night. It helped but my shoulder (front deltoid) would still get extremely tender. Then I started CJC1295/Ipamorelin no DAC, 250mcg 5 days on 2 days off in the morning as soon as I wake up. I didn’t like it right before bed, so I switched to morning. After 1 week of use my shoulder actually started feeling better. I’m on week 4 now and I have the least amount of shoulder pain, almost totally gone, since I injured it in February. Retatrutide worked excellent for me as well. Got up to taking 2mg total split in half 2 days per week. I would also take it in the am. 180lbs in March, now 154lbs. I prefer to take everything in the morning, black coffee and water only, then go lift/run while fasted. However, everyone is different, consistency is everything, so find what works for you and stick to it!
