💬 Should you be taking peptides? From anti-aging promises to superhuman healing - peptides are massively hyped right now, and are being aggressively marketed online. But here’s why you should think twice before giving in to the marketing.

⚡While there are many FDA-approved peptides that you can get your hands on, most of the hype right now is focussed on grey-market, unregulated drugs. Things like BPC-157, TB-500 and the “Wolverine stack”.

In this AMA, Dr Karan answers your top questions about peptides and breaks down the real science behind the online claims.

🎧 Stay tuned to find out:

➡ What a peptide actually is - explained as simply as possible

➡︎ Whether peptides in skincare actually work - and how they differ from injectables

➡︎ If peptides can slow down aging - or help with autoimmune diseases

➡︎ Why marketing is drawing comparisons between peptides and GLP-1s

➡︎ If BPC-157 actually helps with healing and recovery - and the possible dangers

➡︎ The side effects of injecting peptides your body doesn't actually need
