It Seems Bad That Temu Is Selling Peptides
Illustration by Tag Hartman-Simkins / Futurism. Source: Getty Images Silicon Valley’s biohacking obsession with poorly-studied chemical substances has reached its logical endpoint: they’re now buying peptides on Temu. To understand why that matters, it helps to know a little about peptides: short chains of amino acids that act as signalers, telling our cells what to do. Though many peptides occur naturally in our bodies, others do not. As consumables, they’re sold based on the makeup of the amino acid chain, variations of which are said to offer different boosts to cellular functions, like muscle growth, tissue repair, and mental cognition. (GLP-1s, the popular weight-loss medications sold under brand names like Wegovy and Zepbound, are a perfect example of synthetic peptides — albeit ones that have been rigorously studied in human patients.) The drugs have exploded in popularity in San Francisco over recent months, where tech bros take various DIY cocktails as pills, creams or injections to optimize their bodies — a type of biohacking in keeping with the optimization-obsessed startup ecosystem. From those bespoke circles …
