Safety Disclaimer!

Our peptides are exclusively intended for research purposes and are not authorised for use in humans or animals

We are aware that a small portion of the community may attempt to self-administer peptides purchased online, especially those which originate outside of the United Kingdom where manufacturing processes are somewhat unregulated. We strongly advise against such practices due to the significant health risks involved. Without proper knowledge and verification of the chemical composition, the safety and efficacy of these substances cannot be guaranteed. It is crucial to use peptides responsibly within a controlled research environment to ensure both personal safety and the integrity of your scientific work
