As a fitness editor in New York City, I first started picking up chatter about peptides around 2016. Longevity<\/a> was just being written into the wellness lexicon and things like NAD<\/a>, red light therapy<\/a>, and cold plunging<\/a> were taking their first steps into the mainstream. But peptides were an outlier. For one, you had to inject them, which seemed sketchy. More important, there was virtually no research to back up their efficacy. On top of that, they were expensive. So peptides hung back on the fringes, quietly gaining traction among what would soon emerge as the inaugural class of biohackers<\/a>.<\/p>\n

That all changed with the introduction of weight-loss drugs like semaglutide<\/a>, tirzepatide, and, most recently, retatrutide\u2014all peptides. The meteoric rise in popularity of drugs like Mounjaro and Zepbound has in short order stripped much of the doubt and stigma surrounding peptides, including the requisite self-inflicted needle jabs. Meanwhile, as the biohacking crowd has grown increasingly larger\u2014and louder\u2014having infiltrated popular culture through every major entrypoint from Netflix to the podcastsphere, anecdotal accounts of peptides\u2019 benefits have become unavoidable.<\/p>\n

\u201cPeople are generally hearing the word \u2018peptide\u2019 thrown around a whole lot more,\u201d says Dr. Duncan, \u201cwhether that be on social media or in mainstream media, and they’re starting to wonder, \u2018What even is this, what does it do, and should I care?\u2019\u201d<\/p>\n

The tipping point came this past February, when health secretary Robert F. Kennedy Jr. announced that, based on no new findings whatsoever, he would be instructing the FDA to allow pharmacies to resume compounding over a dozen peptides that had previously been banned over safety concerns\u2014including some of the most in-demand formulations (such as BPC-157) that have propped up a thriving online gray market in the meantime. With that change expected to be made in the coming weeks, it\u2019s safe to say we\u2019re going to be hearing a lot more about peptides.<\/p>\n

What are some of the more popular peptides?<\/p>\n

Probably the most popular peptide that you\u2019re likely to hear about is BPC-157, or \u201cthe Wolverine peptide,\u201d as it is commonly known. \u201cI get asked about that one all the time,\u201d says Dr. Duncan. A naturally occurring peptide found in the digestive system, it helps maintain the stomach lining. But when isolated and administered as an injectable peptide, it\u2019s believed to be capable of much more, including accelerating healing and recovery.<\/p>\n

Similarly, GHK-Cu, or GHK Copper, is naturally present in saliva and some other bodily fluids. It\u2019s been reported to boost skin health<\/a> by spurring collagen<\/a> production and supporting cell regeneration. Other popular peptides include MOTS-c, CJC-1295, and TB-500, which are alleged to improve mitochondrial function, release growth hormone, and repair muscle<\/a> and tendons, respectively.<\/p>\n

It\u2019s worth noting that all of these peptides are currently on the FDA\u2019s Category 2, or \u201cDo Not Compound,\u201d list due to significant safety concerns stemming from either a lack of testing or documented adverse effects. In other words, until such time as these peptides are recategorized by the FDA, none can legally be prescribed for human use in the United States\u2014and perhaps for good reason. \u201cSome peptides can impact cell growth, and we need to be mindful of a potential cancer risk,\u201d says Dr. Duncan. Other risks include immune reactions and pancreatitis.<\/p>\n","protected":false},"excerpt":{"rendered":"As a fitness editor in New York City, I first started picking up chatter about peptides around 2016.…\n","protected":false},"author":2,"featured_media":600303,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[36],"tags":[64,63,538,1295,137,64099,532,13221],"class_list":{"0":"post-600302","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-nutrition","8":"tag-au","9":"tag-australia","10":"tag-fitness","11":"tag-food","12":"tag-health","13":"tag-life-advice","14":"tag-nutrition","15":"tag-working-out"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/600302","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=600302"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/600302\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/600303"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=600302"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=600302"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=600302"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
