Yes, BPC-157 can show up in urine drug tests as it is a stable metabolite

Dietary vitamin A equivalents like retinyl esters originating from animal-based products are being intestinally metabolized into retinol by triglyceride lipase or phospholipase B, associated into chylomicrons and secreted into the lymphatic system before reaching the systemic circulation and ultimately being delivered to the liver as the main storage for retinoids or to the side of action resulting in their binding to the retinol-binding protein receptor (RBPR), which enables oxidation of retinyl esters or retinol into ATRA upon entering the target cell

Manufacturing mucoadhesive formulations can also be complicated owing to their complex surface chemistries (such as thiolation or carbomer coating), which make consistent production harder than that of simpler muco-penetrating particle coatings
