Tirzepatide is dual-pathway (GLP-1 + GIP) and semaglutide is single-pathway (GLP-1 only)

Route of Administration How a peptide is delivered dramatically affects how long it stays in the body: Subcutaneous injection : slower absorption, longer duration Intramuscular injection : faster peak concentration, moderate duration Oral and intranasal peptides : often rapidly broken down, requiring protective technologies or higher doses For example, oral BPC-157 may work primarily through gut-localized pathways, while injectable versions may provide broader systemic benefits

Users pleasantly surprised by benefit retention during breaks can adopt cycling approach, while those experiencing concerning decline might choose resuming continuous use or maintenance frequency application
