The Lab

Where science
meets nature.

Every batch of The Muscle Rub is independently tested at an ISO-certified laboratory before it ever reaches your door. Not spot-checked — every batch, every time.

Our Approach

We pioneered the
open-label standard.

When most topical brands were hiding behind proprietary blends and unverified claims, we published everything. Every ingredient, every concentration, and every third-party test result — available to any customer who wants to look.

Our extraction process uses supercritical CO₂ — the same clean, solvent-free technology used in pharmaceutical-grade botanical extraction. It preserves the full potency of each ingredient without introducing chemical residuals into the formula.

Nothing to Hide

In Detail

Testing Standards

Every test is performed using industry-standard analytical methods at an accredited third-party facility.

Purity Testing

ISO Method

Verified free of contaminants

Every batch is screened for foreign materials, adulterants, and contamination at multiple stages of production. Nothing leaves the lab without a clean purity certificate.

Potency Verification

HPLC Analysis

Active ingredients confirmed at stated concentrations

We use HPLC (high-performance liquid chromatography) to verify that every active botanical is present at its stated concentration — not less, not more.

Pesticide Screening

200+ Compounds

Screened against 200+ compounds

A comprehensive multi-residue pesticide screen covers over 200 compounds, including organochlorines, organophosphates, pyrethroids, and herbicides.

Heavy Metal Testing

ICP-MS Method

Lead, arsenic, mercury, cadmium

ICP-MS spectrometry tests for the four primary heavy metal contaminants of concern in botanical extracts: lead, arsenic, mercury, and cadmium.

Residual Solvent Analysis

GC/MS Analysis

No harmful solvents from extraction

Our CO₂ extraction process inherently minimizes solvent residuals, but every batch is still verified through GC/MS analysis to confirm zero harmful solvent carry-over.

Every Order

Certificate of Analysis — every batch.

A full third-party Certificate of Analysis ships with every product we sell. Scan the QR code included in your packaging to view your specific batch results online — anytime, from anywhere.

The COA confirms your batch passed all five testing categories. No guesswork, no trust required — just verified facts.
