For example, many oral versions of peptides (like BPC-157 and Thymosin Beta 4) are not bannedits just the injectables
Beyond these general mechanisms, increasing evidence supports a sequence-specific view of collagen peptides, in which Hyp-containing di- and tripeptides may contribute to bioactivity rather than serving solely as non-specific amino acid sources [45]
