WHY DID PEPTIDE SCIENCES SHUT DOWN OVERNIGHT? The inside story: FDA enforcement, pharmaceutical litigation, and the quality failures behind a $7.4M/month closure Quick answer: Peptide Sciences, the largest U.S. gray-market research peptide vendor, shut down abruptly in March 2026 amid FDA scrutiny and pharmaceutica...

⚠ FOR LABORATORY RESEARCH AND EDUCATIONAL PURPOSES ONLY — NOT FOR HUMAN OR ANIMAL CONSUMPTION. Quick answer: Antimicrobial peptides (AMPs), also called host-defense peptides, are short peptides that many organisms produce as part of innate immunity against bacteria, viruses, and fungi. Because they disrupt microbial memb...

⚠ FOR LABORATORY RESEARCH AND EDUCATIONAL PURPOSES ONLY — NOT FOR HUMAN OR ANIMAL CONSUMPTION. Quick answer: Collagen peptide research covers two distinct areas that are often confused. The first is dietary hydrolysed collagen, where studies have examined whether specific fragments such as Pro-Hyp survive digestion. The ...

Quick answer: PT-141 (bremelanotide) is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH) that acts as a melanocortin receptor agonist, with research focus on the MC3R and MC4R subtypes ex...

⚠ FOR LABORATORY RESEARCH AND EDUCATIONAL PURPOSES ONLY — NOT FOR HUMAN OR ANIMAL CONSUMPTION. Quick answer: The KLOW peptide blend is a four-component research formulation combining GHK-Cu (a copper-binding tripeptide), BPC-157, TB-500, and KPV. Each component has been studied independently in preclinical models across ...

⚠ FOR LABORATORY RESEARCH AND EDUCATIONAL PURPOSES ONLY — NOT FOR HUMAN OR ANIMAL CONSUMPTION. Quick answer: Mitochondrial peptides — also called mitochondrial-derived peptides (MDPs) — are small peptides encoded within mitochondrial DNA rather than nuclear DNA. The best-characterised are MOTS-c and humanin. Published pr...

⚠ FOR LABORATORY RESEARCH AND EDUCATIONAL PURPOSES ONLY — NOT FOR HUMAN OR ANIMAL CONSUMPTION. Quick answer: Sleep and stress peptides are a small, preliminary research category. DSIP (delta sleep-inducing peptide) has the longest history in sleep-architecture studies, while Selank and Semax are examined for anxiolytic a...
