Many researchers have found this simple switch eliminates the response entirely. Think of it this way — subQ is plan A, IM is plan B if plan A keeps causing problems. Quick Recap ∙ Histamine responses are an immune reaction, not a sign of a bad compound ∙ They happen because mast cells in subQ tissue detect the peptide as foreig
