Peptides are a very precise sequence of amino acids that bind to cellular receptors in your body, they play various roles in biological functions including hormone regulation and immune response. They are not steroids or drugs or a magic injectable to cure all your medical ailments. Peptides are like voice commands for your body to remind it how it should be working. They are molecular copies of what your body already produces so there's nothing unnatural about them. They are not a cheat code or an enhancement they are simply factory settings of high performance biology woken up to do their job!
