Peptides & Longevity
The frontier of human performance and longevity — BPC-157 for repair, NAD+ for cellular energy, Spermidine for autophagy, and Stem Cell Support for regeneration. Every compound is third-party tested, free of fillers, and sourced to pharmaceutical-grade standards.

Repair & Recovery
BPC-157
The Body's Master Repair Signal
BPC-157 is a synthetic peptide derived from a protective protein found in human gastric juice. It has shown remarkable healing properties in peer-reviewed research — accelerating recovery from muscle, tendon, ligament, and gut injuries.
TB-500
Accelerated Tissue Regeneration
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide found in virtually all human and animal cells. It plays a critical role in building new blood vessels, muscle tissue, and cell migration.
Longevity & Energy
NAD+
The Cellular Energy Currency
NAD+ is a coenzyme found in every living cell, essential for energy metabolism, DNA repair, and cellular aging. Levels decline 50% by age 50. Supplementing with NAD+ precursors is one of the most researched longevity interventions.
NMN
Direct NAD+ Precursor
NMN is the most direct precursor to NAD+ and has been shown in human trials to raise NAD+ levels by up to 38% within 60 days. Studied extensively by Dr. David Sinclair at Harvard for its anti-aging properties.
Longevity & Cellular Health
Spermidine
Autophagy Activator
Spermidine is a naturally occurring polyamine found in wheat germ, aged cheese, and mushrooms. It's one of the most potent activators of autophagy — the cellular "self-cleaning" process that removes damaged proteins and organelles.
Longevity & Anti-Aging
Epithalon
Telomere Lengthening Peptide
Epithalon is a tetrapeptide (Ala-Glu-Asp-Gly) developed by the St. Petersburg Institute of Bioregulation. It's one of the few compounds shown to activate telomerase — the enzyme that lengthens telomeres, the protective caps on chromosomes that shorten with age.
Regenerative Health
Stem Cell Support Complex
Activate Your Body's Own Repair System
A synergistic blend of compounds shown to support endogenous stem cell mobilization and activity — including AFA blue-green algae extract, fucoidan, and Polygonum multiflorum. These compounds work by signaling the bone marrow to release adult stem cells into circulation.
Structural Support
Marine Collagen Peptides
Bioavailable Structural Protein
Wild-caught marine collagen hydrolyzed into small peptides for maximum absorption. Type I and III collagen supports skin elasticity, joint cartilage, gut lining integrity, and bone density. Marine collagen has 1.5x higher bioavailability than bovine.
Why Kind Earth for Advanced Supplements
Most peptide suppliers are unregulated, untested, and opaque. We do it differently.
Certificate of Analysis
Every batch comes with a third-party CoA showing purity, potency, and contaminant testing.
No Proprietary Blends
Every ingredient and dose is listed on the label. No hiding behind "proprietary blend" language.
Research-Backed Dosing
We dose based on published human clinical trials — not what's cheapest to manufacture.
GMP Certified Facilities
All products manufactured in FDA-registered, NSF-certified GMP facilities.
Be First When New Products Launch
