A Reddit user in a BPC-157 forum, Ryan Beattie, told Undark that he decided to try the peptide last year in an effort to live a healthier lifestyle while weaning off the powerful painkillers he had been taking for more than a decade
BPC-157, formally known as Body Protection Compound-157, is a synthetic peptide consisting of 15 amino acids in a specific sequence: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
In the blood stream as nicotinic acid, it can cause skin flush and this reaction is actually responsible for the tolerable upper limit (UL) for niacin at 35 mg/d for adults in US (20)
For those with sensitive or dry scalps who prefer a different peptide profile, MDhair also offers the Regrowth Serum, which features biotinoyl tripeptide-1 alongside a similar suite of DHT blockers and botanical extracts
Popular healing claims remain unconfirmed BPC-157 is widely promoted for tendon, ligament, joint, muscle, and gut recovery
