Victoria Song’s latest Optimizer newsletter questions whether Gwyneth Paltrow understands peptides after reviewing her Goop skincare line.
How peptide hype connects wellness and tech trends
Song traces the peptide surge to Silicon Valley’s focus on longevity and metabolic optimization, noting how wellness trends shape health tech features and gadgets. She describes peptides as short chains of amino acids that act as bodily messengers, with natural forms from food and synthetic versions made in labs. Insulin and GLP-1 medications like semaglutide and tirzepatide are among the most famous peptides.
Why unregulated peptides are gaining popularity online
Social media promotes peptides in legal gray areas that lack wide testing or FDA approval, often sourced from dubious suppliers. Popular examples include BPC-157, TB-500, GHK-Cu, and CJC1295, which have names resembling Star Wars droids. Song previously covered retatrutide, another weight loss peptide, in Optimizer.
