Peptides are the latest health craze .

However, a sports medicine physician, Dr Jason Chan, has now come forward to issue a chilling warning to those who are injecting the product.

He has said on the Vain-ish Podcast that the unregulated product Eastern Suburbs babes are putting in their bodies could be laced with contaminants.

Called the 'building blocks' of proteins, peptides are short chains of amino acids the body produces to control physiological processes.

Socialites have recently adopted them as the latest wellness trend, largely injecting themselves with unregulated product in the hopes of improving their health.

Dr Chan discussed the troubling trend with podcast hosts Bec Judd and Jessie Roberts on Wednesday.

'There are major concerns in terms of contamination, in terms of purity, whether they've got endotoxins inside,' the former Chief Medical Officer of the Melbourne Storm said.

'There were a couple cases in the US where one of the peptides was being laced with cocaine, clenbuterol because it meant you would use their peptides because you felt wonderful on it.

'So, if we all believe that may not be happening in this country, good luck.'

Dr Chan went on to say that it is 'quite scary' to see how many socialites and influencers are taking peptides 'on a whim'.

'If it can do all the things that we potentially hope it might do, then there may be elements that it is doing what we don't want it to do,' he said.

He even warned that if someone uses an unregulated peptide that wasn't prescribed by a medical doctor, they could risk a fatal allergic reaction.

'You take your first dose, well away from anyone without any knowledge that you're taking that particular dose, which you don't know what is in there, you [could] have an allergic reaction and drop dead,' he said.

Bec, known as the Queen of AFL WAGS, admitted her social media algorithm has been filled with fitness influencers and beautiful socialites advertising the use of peptides to their followers.

'As the availability of unapproved peptide products has increased, so too has evidence of potential risk to consumers.'

The TGA noted peptides are increasingly being .

However, unapproved peptides often don't meet required standards for quality, safety or efficacy.

They could also be incorrectly labelled or promoted and pose risks if used without medical supervision.

'Australians should be very cautious about buying unapproved peptide products online, particularly from overseas websites or through online platforms or social media,' Professor Lawler said.

'If you don't know exactly what's in the vial, where it was made or whether it's sterile, you could be putting your health at serious risk.'

The TGA recently worked with Australian Border Force and Victoria Police to seize $2 million worth of illegal peptides, performance and image enhancing drugs, and steroids.

The agencies will continue to focus on illegal importation, manufacturing, advertising and supply of peptides.

Those found to be breaking laws risk product seizures and import interventions as well as possible civil and criminal charges.

'Consumers are advised that purchasing and using unapproved peptide products, particularly from online, social media or overseas sources, can pose significant health risks,' the TGA said.
