Product Testing
Tested in Utah.
Examined from seven angles.
Every peptide we offer undergoes a seven-point analytical and microbiological testing program in Utah, USA. Together, these tests provide a broader view of identity, purity, and key potential contaminants—because one result never tells the whole story.
A broader standard
Purity is only part of the picture.
A purity result is important, but it cannot answer every quality question on its own. HPLC or UPLC evaluates chromatographic purity and related impurities; separate methods are needed to examine molecular mass, peptide identity or sequence, bacterial endotoxins, elemental impurities, residual solvents, and viable microbial contamination.
That is why Renvara Labs peptides are evaluated through seven complementary testing categories.
The seven-point testing program
Seven distinct checks. One more complete profile.
Each method examines a different attribute of the tested material.
HPLC / UPLC
Purity & related impurities
High-performance or ultra-performance liquid chromatography evaluates the sample's chromatographic purity profile and detects related impurities.
Mass Spectrometry
Molecular mass & identity
Mass spectrometry compares the observed molecular mass with the expected molecular mass to support confirmation of compound identity.
Identity / Sequence
Intended peptide confirmation
Method-appropriate identity or sequence analysis supports confirmation that the tested material corresponds to the intended peptide. The level of sequence confirmation depends on the method used.
LAL / BET
Bacterial endotoxins
Limulus amebocyte lysate or bacterial endotoxins testing screens the sample for bacterial endotoxins.
Elemental Impurities
Heavy-metal screening
Elemental analysis checks for contaminants such as lead, arsenic, cadmium, and mercury.
Residual Solvents
Manufacturing-solvent screening
Residual-solvent analysis checks for solvents that may remain following the manufacturing process.
Sterility Testing
Viable microbial contamination
Sterility testing evaluates the sample for viable microbial contamination under the conditions of the test.
Certificates of Analysis
Understand the report behind your batch.
A Certificate of Analysis (COA) records laboratory findings for a specific sample or production lot. It connects the tested material with the methods used, the measured results and the report details, giving you documentation to review alongside the product information.
What to look for
Review the product identity, lot number, analysis date, laboratory details and test results. Depending on the report, results may include purity, measured quantity or other tested attributes.
Match your lot
Use the product name, vial strength and lot number on your packaging to find the corresponding certificate. A report for one lot does not describe every lot of that product.
Read the testing scope
Each report covers the tests listed within it. Read the methods, specifications and results together; a purity report alone does not document the entire seven-point testing program.
Visit the COA Library to search available reports by product or lot number and open the original laboratory PDFs. The library is the central place to find published certificates as new batches are added.
Tested close to home
Utah-based testing. Greater visibility.
The complete seven-point testing program is performed in Utah, USA. This domestic testing relationship supports direct communication, accessible documentation, and accountability throughout our sourcing process.
Documentation matters
Look beyond a single number.
Meaningful material evaluation requires more than a purity percentage. By combining analytical and microbiological methods, the seven-point program builds a more complete profile of the tested sample.
Frequently asked questions
Understanding the program
What does “seven-point testing” mean?
It describes seven testing categories used for Renvara Labs peptides: HPLC/UPLC, mass spectrometry, peptide identity or sequence analysis, endotoxin testing, elemental-impurity testing, residual-solvent testing, and sterility testing.
Why is HPLC/UPLC not enough by itself?
HPLC or UPLC provides information about chromatographic purity and related impurities. It does not independently answer every question about molecular identity, endotoxins, elemental impurities, residual solvents, or viable microbial contamination, which is why additional methods are used.
Where is the testing performed?
The complete seven-point testing program is performed in Utah, USA.
Does testing mean the products are approved for human use?
No. Renvara Labs products are sold strictly for laboratory research use only. They are not for human or veterinary use, diagnostic use, or use in food. Testing characterizes the sample tested and does not constitute FDA approval or establish suitability for any unapproved use.
