We actually prefer SQ because its painless and has an established track record of effective B12 delivery, whereas IM can be painful and tends to put people off self-injecting

Clinical Relevance: Explains why combination therapy produces synergistic rather than merely additive weight loss

Those that suffer anemia may have better outcomes with an injection versus a supplement

Think of it as the tiny elastic fibers woven throughout your skins structure

This approach inspired other programmes: N-hexanoic-Tyr-D-Arg : enkephalin-derived, protease-resistant, studied for pain N-methyl-Aib inclusions : N-methyl substitutions increase membrane permeability at the cost of partial loss of receptor affinity Beta-peptides and D-amino acids : substitution of natural chiral residues by their D enantiomers, making the peptide invisible to endogenous proteases while (sometimes) preserving function Stapled peptides : hydrocarbon cyclisation, popularised by Verdine (Harvard), stabilises alpha helices and improves cellular penetration These strategies progressively shift the peptide / small molecule frontier
