The Science

Every pen.
Every batch.
Tested and published.

Peptide science is real. The testing is rigorous. The results are documented. Here's how we do it.

What Are Peptides?

Peptides are short chains of amino acids—the building blocks of proteins. Your body naturally produces peptides that regulate sleep, energy, recovery, immune function, and cellular repair. As we age, peptide production declines. This is a major reason we feel less like ourselves.

RENEW peptides are bioidentical versions of naturally-occurring peptides, synthesized in a pharmaceutical laboratory and prescribed by your doctor. They're not hormones. They're signaling molecules that tell your cells what to do.

Think of peptides as instructions. Your body reads them and responds—deeper sleep, faster recovery, better skin, improved energy. That's clinical peptide therapy.

How Our Peptides Work

BPC-157

Recovery

Gut & Tissue Repair

Body Protection Compound. The most researched peptide for gut health. Supports gut lining integrity, accelerates tissue repair, and reduces systemic inflammation.

  • Restores intestinal barrier
  • Accelerates wound healing
  • Reduces leaky gut symptoms
  • Supports injury recovery

TB-500

Restore

Tissue Repair & Healing

Thymosin Beta-4. Upregulates growth factors that accelerate tissue repair and healing. Used by athletes worldwide for joint recovery and tissue regeneration.

  • Promotes tissue regeneration
  • Reduces inflammation
  • Accelerates wound healing
  • Supports joint health

CJC-1295

Vitality

Sleep & Growth Hormone

Growth hormone releasing hormone analog. Stimulates natural growth hormone production for deeper sleep, faster recovery, and sustained energy.

  • Improves sleep quality
  • Accelerates recovery
  • Supports muscle tone
  • Increases daily energy

Ipamorelin

Vitality

Growth Hormone Secretion

GHRP mimetic that selectively stimulates growth hormone release. Often paired with CJC-1295 for synergistic effects on sleep, recovery, and body composition.

  • Promotes deep sleep stages
  • Enhances recovery capacity
  • Supports healthy metabolism
  • Minimal systemic side effects

Semaglutide

Metabolic

Weight Management

GLP-1 receptor agonist. Regulates appetite signaling, improves insulin sensitivity, and supports sustainable body composition change without deprivation.

  • Appetite regulation
  • Improved insulin sensitivity
  • Sustainable fat loss
  • Cardiovascular benefits

GHK-Cu

Restore

Cellular Repair & Aging

Copper peptide. Upregulates genes associated with collagen production, wound healing, and cellular repair. The anti-aging peptide backed by research.

  • Increases collagen synthesis
  • Improves skin elasticity
  • Supports wound healing
  • Anti-aging at cellular level

Our Compounding Process

Pharmaceutical-grade compounding is not supplement manufacturing. It's precision chemistry. Every step is documented, validated, and tested.

  • 1 Source Verification — We source active pharmaceutical ingredients from FDA-registered suppliers with chain-of-custody documentation.
  • 2 Precision Compounding — Licensed pharmacists compound your exact dose in our 503B pharmacy using calibrated equipment.
  • 3 Batch Testing — Every batch is sent to an independent CLIA-certified lab for potency, purity, and sterility testing.
  • 4 Certificate of Analysis — Test results are published and included with your pen. QR code verification included.
Lab testing

Certificate of Analysis (COA)

Every RENEW pen comes with a Certificate of Analysis from an independent, CLIA-certified laboratory. This isn't optional or marketing. It's your proof.

Your COA includes:

Potency — Confirms the exact concentration of active ingredient matches your prescription.

Purity — Tests for contamination, heavy metals, and unwanted substances.

Sterility — Confirms the pen is free of bacteria and fungi (critical for injectable products).

Your lot number — Traceable directly to your pen via QR code.

You can verify your pen's results anytime. This level of transparency is standard in pharmaceutical manufacturing. It should be standard everywhere.

Third-Party Testing

We don't test our own products. An independent, CLIA-certified laboratory handles all potency, purity, and sterility testing. This removes any bias and ensures you get what we promised.

CLIA stands for Clinical Laboratory Improvement Amendments. It means the lab meets federal standards for accuracy, reliability, and safety. Not all compounding pharmacies do this. Most don't. We do.

Every batch. Every lot. Published results. This is the standard of pharmaceutical manufacturing. This is what you deserve.
