The PMG value chain

Testing isn't the cost you avoid. It's the failure you prevent.

Stability, safety, efficacy, and claims substantiation testing determine whether your product can be sold legally, whether it works as claimed, and whether it survives the supply chain. PMG coordinates the full testing portfolio with our accredited laboratory partners.

Testing is what makes a label defensible.

A product without stability data has no defensible shelf life. A product without safety data has no defensible 'gentle for sensitive skin' claim. A product without SPF testing has no defensible SPF value on the label.

The testing portfolio you run isn't a checkbox exercise — it's the documentation trail that lets you make the claims your brand depends on, and that retailers and regulators ask you to prove.

We don't test in a vacuum. We test for the shelf.

01

Stability determines your shelf life claim

A product without stability data has no defensible shelf life claim. Retailers require stability data before purchase orders. We coordinate ICH-compliant accelerated and real-time stability testing on every launch.

02

Safety testing protects your brand and your customers

HRIPT (human repeat insult patch test) and similar studies are the standard for personal care and cosmetic safety substantiation. We run them through accredited partners and document the results for retailer and regulator review.

03

Claims substantiation is the difference between marketing and a Warning Letter

'Clinically proven,' 'dermatologist-tested,' 'reduces inflammation' — each requires specific documentation. We design the study protocols, coordinate the labs, and document the results to FDA (Food and Drug Administration) and FTC standards.

What a PMG testing & stability engagement looks like.

  • Stability testing (ICH-compliant accelerated and real-time)
  • Microbial / challenge testing (USP 51 preservative efficacy)
  • Compatibility testing (product-packaging interaction)
  • Safety testing (HRIPT, RIPT, irritation)
  • SPF testing (FDA-protocol for sun care)
  • Water-resistance testing
  • Claims substantiation studies (clinical testing coordination)
  • Heavy metals and contaminant testing
  • Identity and potency testing (supplements)
  • OTC challenge testing

Testing & Stability questions buyers ask us first.

Accelerated stability testing typically runs 3 months and supports an initial shelf life claim. Real-time stability testing runs in parallel and substantiates the final shelf life claim once complete.

Yes. 'Clinically proven' is a specific claim that requires properly designed, properly powered, and properly documented clinical studies. We coordinate study design and execution with our accredited clinical testing partners.

Yes. SPF testing, water-resistance testing, preservative efficacy testing, and other OTC-required testing are all coordinated through our accredited partners.

You do. All testing data and reports are delivered to you and become part of your product's regulatory documentation file.

Testing is the documentation trail behind every defensible claim. The brands that win in regulated categories are the ones that build the trail correctly the first time.
