Build Your Panel

Build your panel

Start with purity. Add what you need.

Every panel starts with HPLC purity analysis. Add identity confirmation and safety screening as you need them - nothing you don't.

Always included

✓

Branded CheckPeptide COA

Professionally formatted certificate with your COA ID, results, methodology, and lab accreditation - publicly verifiable at /verify.

✓

Clear result summary

Plain-English interpretation of your results - not just raw numbers.

✓

3–5 business day turnaround

Starts when the lab receives your sample.

HPLC Purity Analysis Included

Measures the percentage of target peptide in your sample. Detects underdosing, degradation, and synthesis impurities.

Identity + Quantification Recommended+$126

HPLC retention time concordance (USP <621>) against a certified reference standard, plus exact mg/vial quantification.

Heavy Metals + Endotoxin +$374

ICP-MS screening for lead, arsenic, mercury, cadmium, plus bacterial endotoxin detection - critical for anything injected.

Vendor & B2B

Pharma-grade panels for vendors and clinics.

Pharma grade

Advanced Panel

The compounding-pharmacy standard. Eight tests - purity, identity, quantification, and every major safety parameter. Add amino acid analysis for the most rigorous identity check available.

Always included

✓

HPLC Purity Analysis

Full purity measurement.

✓

Identity Confirmation

HPLC retention time concordance (USP <621>) against a certified reference standard.

✓

Peptide Quantification

Exact mg/mL concentration - confirms stated dose is accurate.

✓

Heavy Metals (ICP-MS)

Lead, arsenic, mercury, cadmium screening.

✓

Endotoxin Testing

Bacterial endotoxin detection.

✓

Sterility Testing

Confirms absence of viable microorganisms.

✓

Residual Solvents

Detects toxic synthesis solvent residues.

✓

Moisture Content

Measures water content - affects dosing accuracy in lyophilized peptides.

Amino Acid Composition Analysis +$700

Confirms the exact amino acid sequence and composition of your peptide - the gold standard for identity verification. Catches substitution fraud that mass-based methods alone can miss.

3–5 business days standard. Sterility testing minimum 48 hours.

Who this is for

High-frequency peptide users wanting full documentation
Clinics and practitioners requiring pharma-grade verification
Vendors wanting court-defensible documentation - add amino acid analysis

Sample requirement

7 vials required. Vials are consumed during testing and not returned.

Vendor / B2B

Vendor Validation

Batch-level certification, not a single vial. 3 representative samples, 9 tests each - the documentation standard that builds customer trust and holds up under scrutiny.

✓

HPLC Purity Analysis

Measures the exact purity percentage of the target compound.

✓

Peptide Quantification

Exact mg/mL concentration - confirms stated dose is accurate across all 3 samples.

✓

Identity Confirmation

HPLC retention time concordance (USP <621>) against a certified reference standard, confirmed across all 3 samples - can't be fooled by look-alikes.

✓

Heavy Metals (ICP-MS)

Screens for lead, arsenic, mercury, and cadmium from synthesis catalysts.

✓

Endotoxin Testing

Detects bacterial endotoxins - critical safety check for any injectable compound.

✓

Sterility Testing

Confirms absence of viable microorganisms in all 3 samples.

✓

Residual Solvents

Detects toxic organic solvent residues from the synthesis process.

✓

Moisture Content

Water content measurement - affects dosing accuracy in lyophilized peptides.

✓

Amino Acid Analysis

Confirms exact amino acid composition - the gold standard for identity. Catches substitution fraud that mass spectrometry alone can miss.

Why 3 samples from one batch?

Testing a single vial tells you about that vial. Testing 3 representative samples from the same batch tells you about the batch - which is what your customers are actually buying. Statistically defensible batch certification requires multiple sample points.

Who this is for

Peptide vendors and suppliers
Compounding facilities and clinics
Anyone selling peptides who needs third-party documentation
Group buys - one submission, split the cost
