Plenty of people run both at the same time, myself included.
I want to lose 30 pounds from 196 down to 175 at 5 foot 10 with a pear-shaped waist. Desk work keeps me inactive most days, though I still carry some muscle from training years ago. After looking into options I think retatrutide fits my needs and I intend to increase the dose very gradually to limit stomach problems. My biggest worry is muscle loss, so I am wondering what else could be added to protect it. I also plan to add GHK-Cu for hair thinning and sun-damaged skin and would like to know how well the two work together. Any other suggestions are welcome.
