Welcome to the molecular core of Lab of RAD—where beauty meets biochemistry and performance is powered by peptides. We believe that understanding the science behind our formulas isn’t just empowering—it’s essential. Here’s your deep dive into the molecules that are changing skincare, wellness, and the way we age.

What Are Peptides? (And Why Should You Care?)

Peptides are short chains of amino acids—the building blocks of proteins. In your body, peptides serve as cellular messengers that tell your skin, muscles, or organs what to do, when to do it, and how intensely to react. Think of them as microscopic emails sent between cells, carrying instructions like “build collagen,” “calm inflammation,” or “stimulate growth.”

There are thousands of peptides naturally produced in the body. Each has a unique role, depending on its sequence of amino acids. Lab of RAD’s mission is to harness the most effective ones and deliver them in skin- and body-friendly ways.

The Peptide Hype (Spoiler: It’s Deserved)

The skincare and health industries are having a full-blown peptide moment—and for good reason. From dermatologists to biohackers, everyone’s tuning in to what these tiny molecules can do.

🔬 The GLP-1 Craze

Let’s talk about the elephant in the peptide room: GLP-1 receptor agonists, like Semaglutide and Tirzepatide. Originally developed to manage blood sugar in Type 2 diabetes, they’ve become a global sensation for weight management and metabolic health. GLP-1 mimics a hormone that slows gastric emptying, reduces appetite, and improves insulin sensitivity.

These injectable peptides have redefined the obesity and longevity conversation—and they’re just one category in a vast molecular universe.

  • BPC-157: A regenerative peptide that accelerates tissue repair and gut healing.
  • TB-500 (Thymosin Beta-4): Used to reduce inflammation and promote muscle recovery.
  • Melanotan II: Enhances tanning, libido, and energy via melanocortin receptors.
  • GHK-Cu & AHK-Cu: Our heroes in skin regeneration and follicle health (see below!).

The point? Peptides aren’t just hype. They’re precision tools—each designed to trigger specific biological processes, naturally and efficiently.

Why We Love GHK-Cu and AHK-Cu

GHK-Cu: The Cellular Rejuvenator

Learn more about GHK-Cu

Discovered in the 1970s, GHK-Cu (Copper Tripeptide-1) is a naturally occurring peptide complex with three amino acids and a copper ion. It plays a key role in tissue remodeling, wound healing, and anti-inflammatory response.

In skincare, GHK-Cu has been shown to:

  • Stimulate collagen and elastin production
  • Improve skin firmness, elasticity, and clarity
  • Enhance wound healing and reduce scarring
  • Reverse signs of photoaging and environmental stress

It’s not just a cosmetic ingredient—it’s a signal peptide that tells your skin to regenerate itself. That’s what we call RADical repair.

AHK-Cu: The Follicle Whisperer

Learn more about AHK-Cu

AHK-Cu (Copper Tripeptide-3) is a structural analog of GHK-Cu but with a twist: it specializes in supporting hair follicle function.

What it does:

  • Promotes angiogenesis (blood vessel formation) around hair roots
  • Increases expression of growth factors like VEGF
  • Reduces follicle miniaturization
  • Prolongs the anagen (growth) phase of hair

In short, it gives your hair a biochemical pep talk—and the results speak for themselves.

How We Deliver Peptides Effectively

Peptides are powerful—but delicate. They need the right environment to stay stable, active, and bioavailable. At Lab of RAD, we obsess over delivery methods. That’s why we:

  • Use airless pumps to protect actives
  • Maintain optimal pH levels for stability
  • Pair peptides with carrier ingredients like lecithin and glycerin to enhance skin penetration
  • Use liposomal encapsulation where needed

We formulate in-house, so we control every variable—from molecular sourcing to final product pH.

What Makes Lab of RAD Different?

We’re not here to follow trends—we’re here to set the molecular standard.

  • Formulated in-house: No white-label outsourcing. Every formula is ours, from molecule to moisturizer.
  • Clinical-level peptides: We don’t sprinkle actives—we dose with purpose.
  • Clean, synergistic ingredients: Natural when possible, always functional.
  • Science-backed, not science-washed: We explain the why, not just the what.
  • Peptide-centric design: Every product begins with the question, “What does the molecule want to do?”

Where We’re Headed

The future of beauty and wellness is bioactive—and Lab of RAD is leading the way.

We’re expanding our formulations to include:

  • Next-gen topical and transdermal delivery systems
  • Supplement-based peptide support
  • Functional skincare powered by real-world clinical research
  • Community-driven transparency and testing

Join us as we reinvent the glow-up—one molecule at a time.
