Provided herein are oligonucleotides, chimeric peptides, and peptide-oligonucleotide-conjugates, the chimeric peptides and peptide-oligonucleotide-conjugates comprising at least two cell-penetrating peptides, wherein at least one of the cell-penetrating peptides is an amphipathic peptide and at least one of the cell-penetrating peptides is an oligoarginine peptide. The oligoarginine peptide comprises the sequence [(RYR)] (SEQ ID NOs: 15-18), wherein R is arginine, Y is independently selected from aminohexanoic acid (X) or β-alanine (B). Also provided herein are methods of treating a muscle disease, a viral infection, or a bacterial infection in a subject in need thereof, comprising administering to the subject oligonucleotides, chimeric peptides, and peptide-oligonucleotide-conjugates comprising at least two cell-penetrating peptides, wherein at least one of the cell-penetrating peptides is an amphipathic peptide and at least one of the cell-penetrating peptides is an oligoarginine peptide described herein.
