Polypeptide Group makes outstanding peptides — the quality is undeniable. But as a mid-size biotech we sometimes find their minimum order quantities and lead times challenging. They're set up for large pharma orders, not small research batches. If you need 100g+ of a GMP peptide, they're perfect. For smaller research quantities, you'll need to look at their non-GMP catalog or elsewhere.
