Many peptides are unlikely to ever receive FDA approval because their simple, easily replicated structures make them commodities. Pharma companies won't fund billion-dollar trials for drugs they can't patent, leaving them in a permanent gray market.

The debate isn't about peptides replacing antibodies but about combining them. The future lies in hybrid therapeutics, such as grafting peptides into antibody CDRs or creating fusions that use a peptide for optimal target binding and an antibody scaffold for effector functions, half-life extension, and stability.

The company positions its peptide platform as the ideal middle ground in drug development. They aim to create medicines that are functionally like highly selective, less toxic large biologics (e.g., antibodies) but are structurally designed for the convenience of an oral pill, combining the best attributes of both major drug classes.

The dominance of peptides for GLP-1 therapeutics isn't a failure of antibodies but a success for picking the right tool. Peptides have a natural advantage when the therapeutic strategy involves engineering a natural ligand, making them a better starting point for certain targets like GPCRs.

The critique of the peptide trend often misses that users aren't taking unknown chemicals. Many use compounds like Retatrutide, which is already in Phase 3 clinical trials by Eli Lilly. They are essentially front-running the FDA approval process for drugs that already have substantial clinical backing.

Martin Shkreli dismisses the biohacking trend of using peptides. He argues that without rigorous data on pharmacokinetics—how a substance is metabolized and its half-life—one doesn't have a medicine, but a delusion. He criticizes enthusiasts for ignoring the foundational science required for any pharmaceutical.

Martin Shkreli posits that the rise of self-experimentation with peptides is fueled by psychological drivers—a desire for personal control, identity, and a fundamental distrust of established institutions like the pharmaceutical industry. This frames the trend as a cultural phenomenon, not purely a medical one.

CEO Jonathan Steckbeck simplifies a complex topic by describing peptides as a "Goldilocks modality." They sit between small molecules (good access, poor specificity) and biologics (poor access, good specificity), ideally offering the best of both worlds for targeted drug delivery.

Shkreli dismisses the peptide trend popular in tech circles. He contends that without understanding a drug's half-life (pharmacokinetics), its specific biological target, and rigorous double-blind trial data, users are engaging in delusion, not science. He criticizes the dismissal of the FDA and established pharma processes.
