Administration by Injection or Infusion

Due to the lack of activity after oral administration for most peptides and proteins, administration by injection or infusion - that is, by intravenous (IV), subcutaneous (SC), or intramuscular (IM) administration - is frequently the preferred route of delivery for these drug products.
