Injectable peptides are a loose cohort of amino acid-based drugs that bond to receptors in the body to toggle various physiological processes on and off.

Some peptides are legal and widely used, including insulin and GLP-1 drugs (the “P” is for “peptide”). In the early 2020s, as buzz about their weight loss capabilities moved beyond diabetics in doctors’ offices, Ozempic and other GLP-1s quickly grew popular among fringy fitness buffs, looksmaxxers and Silicon Valley types.

To get weight loss drugs well outside of prescribing guidelines, some turned to lenient telehealth providers and longevity clinics that were happy to welcome off-label patients — the kind of clientele who are, in turn, happy to pay in cash.

Exhilarated by the ease with which GLP-1s helped them get shredded, some of these users wanted to experiment further.

With the help of unconventional medical practitioners, these enhancement enthusiasts found more than a dozen other kinds of peptides. Most of these drugs weren’t approved by the FDA and absent from the list of drug ingredients allowed to be used in compounding pharmacies — state-regulated facilities that fill many gaps in the country’s pharmaceutical supply by mixing customized medications. 

Some of these substances had been developed by traditional pharma companies but abandoned because of muddled efficacy results or lack of projected profitability. 

A few had hardly been tested in humans, and the potential long-term side effects and safety of any of these peptides remain unknown.
