Peptides are short chains of amino acids, the fundamental building blocks of proteins. Think of them as mini-proteins that act like biological messengers, directing your body’s functions. They’re naturally produced in the body, but levels decrease with age.

Peptides are highly specific in their action, each targeting particular systems in the body. Some support brain function and mood, others promote muscle growth and recovery (such as Sermorelin), while others aid sleep, energy, metabolism, skin repair, hormone balance, and more.

Peptide therapy can lead to improved energy, sharper mental clarity, faster recovery from workouts or injuries, better mood, enhanced sleep, leaner body composition, and improved libido and hormonal balance.

Most peptides are delivered via subcutaneous injection using a tiny needle into the fat layer. Some are taken intramuscularly, others as nasal sprays for fast brain access, capsules for gut-related effects, or topical creams for skin repair. IV administration is rare and generally unnecessary.
