Since starting peptides about 7 weeks ago, I have noticed a pretty dramatic increase in difficulty doing high output activities such as hiking, and uphill mountain biking. My watch tells me HR still maxing out around 180 which was standard pre-peptides but now this happens so much sooner and I feel so much worse when it does (out of breath, nauseous, etc.) I belive this may be related to Retatrutide because I started to notice before I introduced SS31 & MotsC. This is happening even on the weekends when I take a break from pinning anything. I'd love to hear thoughts on this! Current Stack: Reta - 3mg total/wk MWF SS31 - 1mg 5x/wk MotsC - 1mg 5x/wk Wolverine - 500mcg each 5x/wk GHKCU - 2mg 5x/wk
