00:02An analytical chemist quickly upskilling.
00:05This time last year I had never heard of peptides or never tested peptides.
00:09October 2025 we started getting almost daily requests for purity testing of peptides.
00:15The most common request is for black market knock-offs of weight loss peptide retitrutide.
00:21It's about 30% of all of the peptide testing that we do.
00:24The majority of vials tested don't contain the amount of peptide advertised on the label.
00:30There's a huge range, some containing none, some containing almost double and only one matching what the label says.
00:38The lab tested three vials of counterfeit retitrutide for the ABC and the University of Queensland.
00:44Each vial's label said the product contained 10mg of the peptide.
00:48The results showed one vial had about half that while the other two had a lot more.
00:56So between the three of them, huge variability.
00:59UQ peptide expert Tim Piakowski was surprised by the results.
01:03I definitely didn't expect that level of overdosing, that there'd be a greater number of overdosed vials than underdosed.
01:12If you're doing this yourself, without knowing the concentration and without medical supervision, there is a much higher risk of
01:19very dangerous potential side effects.
01:22Liver specialist Marie Sinclair has recently treated patients with liver failure after taking retitrutide.
01:28She's concerned there are also many other dangers that were not tested for.
01:32Unless you're specifically testing for every single potential contaminant, it's impossible to know for sure, safely, what is inside the
01:41vials that people are purchasing.
01:44Retitrutide is still in development by US pharmaceutical giant Eli Lilly.
01:48It told the ABC any version of the drug available online is unapproved, unverified and simply not worth the risk.
01:56The Therapeutic Goods Administration continues to warn against the risks of unapproved peptides.
02:03Thank you very much.
02:04The following lesson seconds are focused on pace forая Prosieben.
02:05Do people already knew once?
02:05What really ===
02:06helfen sehen.
02:06Do people know the hell we're in LA.
02:06One day will be possibly catching up.
02:06We were able to answer a project when they're talking about.
