I feel like I’m late to the party to be offering my opinion on peptides here in the online space 🙂 But let’s go.
In March 2026, I attended South Africa’s first certification course on the clinical use of peptides, where we explored theirgrowing role in modern medicine. Hosted by Comp Pharm, Dr Edwin Lee from the USA lead the day in academic discussion and presentation.
While there is legitimate medical use for certain peptides (with well-known examples including insulin and GLP-1 medications), much of what is currently promoted online is not supported by strong human research.
Because peptides cannot be patented in the same way as traditional pharmaceuticals, large-scale clinical trials are often lacking, which means safety and long-term data remain limited for many of the compounds being marketed. And will remain so unfortunately. For this reason, my approach remains measured and cautious.
Peptides may have a role in selected cases, but they are never a substitute for the foundations of good health — including nutrition, movement, sleep, stress management, and overall lifestyle.
When these fundamentals are in place, certain therapies may offer additional benefit. Without them, they are unlikely to deliver meaningful or lasting results.
How they interact, where they are sourced and where they are used in your health matter - some have side effects, some interact with supplements and nutrients and some have absolutely no evidence of any therapeutic benefit.
That’s why using them under the guidance of a doctor matters so, so much. If you’re interested in incorporating them into your longevity program, we can discuss it as we do with all other interventions.
Do I personally use peptides? I do from time to time. For me, some have been amazing (it’s not those popular ones interestingly), others haven’t but it is a choice I’ve made with the information available to me - as an educated doctor and not as an influencer chasing trends and a sales code.
