Primeva Labs Quality Assurance
Quality You Can Verify, Not Just Trust
Every batch is independently tested across six standards. Here is what each check confirms — and why it matters before use in a laboratory setting.
Identity Lambda Max
Confirms the submitted sample matches the labeled compound by its characteristic UV signature before deeper analysis.
Why it matters: You receive the right molecule — no substitutions.
Purity % HPLC
Measures how much of the sample is the target compound versus related impurities, by correlation against a reference standard.
Why it matters: Real visibility into cleanliness, not an unsupported claim.
TAMC Aerobic Count
Total aerobic microbial count — a bacterial contamination screen on the tested sample.
Why it matters: Documents the bacterial burden of the lot.
Quantitative Assay Beer-Lambert
Quantifies the actual peptide mass present in the vial against the labeled amount.
Why it matters: You get the milligrams you paid for — measured, not estimated.
Heavy Metals Total Quantity
Screens the sample for total heavy-metal contamination such as lead, cadmium, and mercury.
Why it matters: Confirms the lot is free of toxic metal residues.
TYMC Yeast & Mold
Total yeast & mold count — a fungal contamination screen on the tested sample.
Why it matters: Confirms the lot is free of fungal growth.

FAQ
Common Research Supply Questions
Quick answers about documentation, testing, shipping, and research-use positioning.
Are Primeva Labs products tested?
Primeva Labs emphasizes batch-specific quality documentation, including identity, purity, assay, heavy metals, TAMC, and TYMC testing where available.
What is a Certificate of Analysis?
A Certificate of Analysis is a lab document that helps researchers review available batch-specific quality data before purchase or handling. Each one is browsable in our public CoA Library.
Are these products for human use?
No. Primeva Labs products are sold strictly for research use only and are not intended for human consumption, administration, clinical use, or medical use.

How fast do orders ship?
Orders are prepared for fast fulfillment, with many processed within 24 hours depending on order timing, inventory, and carrier availability. Shipping is free on orders over $250.
How should compounds be stored?
As general handling information: lyophilized powder is typically kept long-term at -20°C, and once reconstituted is kept at 2–8°C and used within about 30 days. Avoid freeze/thaw cycles and protect from light.
Do I need an account to order?
You can browse the catalog freely. An account is required to complete checkout and is created automatically as you place your order.
