Cosmetic Scalp Serum Testing for Peptides, Active Ingredients, and Undeclared Drugs

Seeking independent analytical testing of a finished cosmetic scalp serum sold with a microneedle applicator. We can supply several sealed, unopened units, preferably from multiple production batches. Testing is requested to verify the identity and concentration of the following labeled ingredients and screen for undeclared pharmaceutical actives.

Requested Testing:

1. Peptides and Copper: Copper tripeptide-1 (GHK-Cu), biotinyl tripeptide-1, acetyl tetrapeptide-3, and total copper content.

2. Other Active Ingredients: Diaminopyrimidine oxide, pyrrolidinodiaminopyrimidine oxide, azelaic acid, melatonin, caffeine, biotin, and adenosine.

3. Undeclared Pharmaceutical Actives: Screening for undeclared drug ingredients, including minoxidil and finasteride.

Laboratory Quotation Requirements:

• Identify which analyses are covered under ISO/IEC 17025 accreditation and which would require method development.

• Confirm whether peptide reference standards are required and whether the laboratory can source them.

• Provide pricing per analyte or as a testing package, along with estimated turnaround times.

• Specify minimum sample quantities and shipping requirements.

• Confirm availability of a comprehensive analytical report detailing methods, results, and detection limits.

• Recommend any adjustments to the testing scope that could reduce costs while maintaining meaningful analytical results.
