Peptide Quality Guarantee (Highest in the Industry)

At Peptide Tech, quality is our foundation. Every batch of our Research Use Only (RUO) peptides undergoes rigorous, independent testing to ensure you receive the highest purity and accurate content for your critical research. We proudly publish our strict release specifications and our internal targets, which consistently exceed industry standards.

1. Identity and Purity Assurance

We use advanced analytical methods to guarantee that the product in the vial is exactly what the label claims, and that it contains minimal impurities.

Standard	Method & Release Specification	Peptide Tech Internal Target
Purity	RP-HPLC (Reversed-Phase High-Performance Liquid Chromatography)	98.5% – 99.5%+
	Release Specification: $\geq$ 98.0% (area % by HPLC)
Identity	LC-MS (Liquid Chromatography-Mass Spectrometry)	Confirmed (Exact match of observed mass to calculated mass)

COA Reporting: Your Certificate of Analysis (COA) includes the full HPLC chromatogram, the percent area of the main peak, and the LC-MS observed and calculated mass-to-charge ( $m / z$ ).

2. Content Accuracy (Quantity vs. Label Claim)

Accurate dosing is vital for your research. We ensure the active peptide content matches our label claim after correcting for moisture content.

Standard	Method & Release Specification	Peptide Tech Internal Target
Assay Content	Amino Acid Analysis (AAA) or validated HPLC assay versus a certified reference standard; moisture corrected.	98.0% – 102.0%
	Release Specification: 87.5% – 115.0% of label claim

COA Reporting: The COA provides the final Assay %, the method used for reference, and the lot sample data.

3. Trace Impurity Screening

3.1 Bacterial Endotoxins (For Low-Endotoxin Research)

For applications requiring low levels of bacterial contamination, we perform specific testing to measure endotoxin load.

Standard	Method & Release Specification	Peptide Tech Internal Target
Endotoxin Level	USP <85> (LAL / Recombinant Methods), reported as Endotoxin Units (EU) per mg of peptide.	$\leq$ 0.25 EU/mg
	Release Specification: $\leq$ 1 EU/mg

COA Reporting: Includes the test method, maximum valid dilution (MVD), and the final result in EU/mg.

3.2 Sterility and Microbiology

We test for the presence of microbial growth to ensure the integrity of the product.

Standard	Method & Release Specification
Sterility	USP <71> Sterility Test (using membrane filtration or direct inoculation with a 14-day incubation period).
	Release Specification: No growth (Pass)

3.3 Elemental Impurities (Heavy Metals)

We test for common heavy metal contaminants to ensure safety standards that are often tighter than typical raw-material specifications.

Standard	Method & Reportable Limits
Heavy Metals	ICP-MS (Inductively Coupled Plasma Mass Spectrometry) per USP <233> and aligned to ICH Q3D risk-based limits.
	Reportable Limits: Arsenic (As) $\leq$ 1.5 ppm, Cadmium (Cd) $\leq$ 0.5 ppm, Lead (Pb) $\leq$ 0.5 ppm, Mercury (Hg) $\leq$ 0.1 ppm.

COA Reporting: Details the results for each element in parts per million (ppm), the method, and system suitability controls.

Yes. We’re partnered with a GMP-aligned U.S. facility, giving you domestic quality systems and documentation at overseas-level pricing.

Do you offer custom peptide synthesis?

Yes—any sequence (linear/common modifications). We quote based on sequence length, modifications, scale, and QC package.

What is your standard RUO Purity Specification?

A: ≥ 98.0% area by HPLC (target 98.5–99.5%+), confirmed by LC-MS for identity.

How fast can you ship?

In-stock catalog SKUs often ship same-day/next-day (Mon–Fri) if the order is confirmed before 3 PM CST. Customs are quoted per project; expedited options available.
