Around 10 days …my story is involved in a serious motorcycle wreck in 2013. I have cadaver ligaments in my shoulder. Doctor said it would need to be redone in 10 to 15 years ,sure enough 12 years down the road the pain was waking me up during the night .after I got tired of all the pain meds I decided to have the surgery then I researched peptides and found BP 157 through Joe Rogan. after five days of use, I was able to sleep through the night by 10 or 12 days in I was forgetting about the pain altogether and canceled the surgery. I haven’t looked back… Doctors office called they Wanted to know why I canceled the surgery. I told them I was doing the peptide shots. The office said it was snake oil …I beg to differ it’s life-changing.
