Science & Evidence

Rooted in clinical literature, not wellness hype.

Livozo protocols are built on peer-reviewed research into the signaling peptides and cofactors that influence how the body repairs, recovers, and regulates itself.

Mechanisms of action

How these peptides actually work.

Peptides are short chains of amino acids that act as precise biological signals. Rather than overriding the body, each protocol nudges a pathway the body already uses — the growth-hormone axis, cellular energy metabolism, redox balance, or tissue repair.

Growth-hormone signaling

Sermorelin is a growth-hormone-releasing-hormone analog that prompts the pituitary to produce growth hormone on its own natural rhythm, supporting sleep quality, recovery, and lean-tissue maintenance.

Cellular energy & redox

NAD+ is a coenzyme central to mitochondrial energy production and DNA repair; glutathione is the body's primary intracellular antioxidant. Both decline with age and physiological stress.

Repair & receptor pathways

GHK-Cu is a naturally occurring copper peptide studied for skin and tissue remodeling, while PT-141 acts on melanocortin receptors in the central nervous system involved in sexual arousal.

Our approach

How we read the evidence.

Peer-reviewed

Protocols are grounded in published peptide and cofactor research rather than anecdote or marketing claims.

Individualized

A licensed clinician reviews your history and goals before any prescription is written — no one-size-fits-all dosing.

Labs-informed

Where a protocol warrants it, baseline and follow-up lab work guides safe, evidence-based dosing.

Monitored

Ongoing clinician follow-up is built into care, not an afterthought, so the plan can adjust as you do.

Peptide therapies are prescribed off-label and as compounded preparations. Evidence quality varies by peptide, and individual responses differ. We do not promise specific outcomes; your clinician will discuss what the literature does and does not support for your situation.

Baseline panels

Where indicated, we review comprehensive metabolic panels (CMP), lipid profiles, and relevant markers to establish a clear baseline before treatment begins.

Targeted assays

For protocols that affect the growth-hormone axis or hormonal balance, precise measurements help your clinician dose safely and conservatively.

Ongoing monitoring

Because any prescribed therapy can interact with kidney, liver, or metabolic function, follow-up review is a core part of the care pathway.

Medication Safety

Understanding compounded medications.

Important clinical disclosure: The peptides in our protocols — PT-141, sermorelin, NAD+, glutathione, and GHK-Cu — are dispensed as compounded preparations made by state-licensed compounding pharmacies based on an individual patient prescription. Compounded medications are not FDA-approved, and the FDA does not evaluate them for safety, efficacy, or quality prior to dispensing. Livozo strictly partners with accredited 503A compounding facilities.
