What is peptide stacking? Biohackers jump on risky trend cheaper than stem cell therapy
Taking multiple synthetic peptides to target goals like weight loss, muscle growth and injury recovery is not without its risks, experts say
Jennifer Lynn knows she is a “guinea pig”. The 43-year-old former ice hockey player turned athletic coach, who is based in Tampa Bay, Florida, has been “stacking” synthetic peptides for the last year. It is a trend that some see as the future of medicine, but others view as a reckless gamble.
“I know a lot of people who are sceptical and who are not willing to be guinea pigs,” she says.
“While I never push peptides on my clients, I will tell people about my experiences if they ask. Personally, I feel good on it, strong and well-recovered. If I stop taking it, I notice.”
Lynn is no casual user; she is a high-performance athlete, working with a coach herself four to five days a week. Her routine involves hurdles, explosive sprints and “jump training” exercises, designed to increase muscle power, speed and strength. Rapid muscle recovery is crucial for her.
What is peptide stacking?
Peptides are short chains of two or more amino acids – the building blocks of proteins – linked by peptide bonds. They are not exotic chemicals; they are signalling molecules that your body already produces naturally.
Insulin, oxytocin and growth hormones are all peptides that tell your cells how to act, whether to repair a tear, produce collagen or regulate your metabolism.
