A recent article in Mens Journal and The Washington Post are examples of the ongoing discussion raging over the safety of peptides that followed AP reporting on unapproved peptides on November 14, 2025

Tabata et al., 1999) are illustrative for the pertinence of the poorly resolved problem, illustrative for the diversity of the carriers (i.e., hyaluronate gel carrier (Wang and Aspengberg, 1996), alginate/heparinsacharose microspheres and films (Yu et al., 1998), cellulose gel (Thorn and Aspenberg, 1993), defective form of Pseudomonas exotoxin (Siegall et al., 1994), fibrin adhesive carrier (Walter et al., 1996), biodegredable hydrogen gelatin (Tabata et al., 1999), natural coral, and collagen (Damien et al., 1993))

The minimal sequence of RGD is often combined with different amino acid linkers to form RGD peptides, such as GGGGRGDY, 24,25 GCGYGRGDSPG, 39,40 GRGDSP, 41 and GGGGRGDSY

Most notably, domperidonea dopamine receptor antagonist that does not typically cross an intact BBBwas found to exert central behavioral effects in lesioned animals, indicating a functional breach of the barrier (Carvey et al
