05THIRD-PARTY VERIFIED
Quality you can verify, not just trust.
Every batch is independently tested by accredited U.S. laboratories. We don't ask you to take our word for it - we hand you the proof, on the record, with every lot.
99.94%Documented purity by HPLC
100k+Active researchers served
<4 hrMedian support response
Verified potency
HPLC confirmedEvery vial is assayed by HPLC to confirm it contains exactly what the label states, quantified against a reference standard - no approximations.
Why it matters: peptide content directly determines research outcomes. Underdosed vials waste time and confound the data.
Documented purity
≥99% by HPLCReverse-phase HPLC integrates the target peak as a share of total area; the full chromatogram is published on each lot's Certificate of Analysis.
Why it matters: impurities introduce uncontrolled variables. A pure starting material is a prerequisite for reproducible work.
Characterized stability
LyophilizedCompounds ship lyophilized with factual storage guidance - −20 °C long-term, 2–8 °C short-term - recorded for the researcher on the certificate.
Why it matters: correct storage preserves integrity across a study, so material handling can be planned with confidence.
Screened for safety
Endotoxin · metalsEach lot is screened for bacterial endotoxin by LAL and for heavy metals by ICP-MS, with the results recorded on the lot Certificate of Analysis.
Why it matters: contaminants can invalidate assays and damage cell cultures. Screening keeps confounders off the bench.
Lot-to-lot consistency
Archived COAsEach lot must meet defined acceptance criteria before release; prior and current certificates are archived so they can be compared directly.
Why it matters: reproducing an experiment with a new lot should be predictable - consistent specifications make that possible.

06FAQ
Your Questions Answered
The details that matter before you order: purity, documentation, handling, and delivery.
Each lot is analyzed by an independent laboratory using reverse-phase HPLC to quantify the target compound as a percentage of total peak area. A result of 99%+ means the lot's chromatogram shows the target peptide at or above 99% purity. Identity is separately confirmed by mass spectrometry. Both results are recorded on the lot-specific Certificate of Analysis.
A Certificate of Analysis is a third-party analytical report tied to a specific lot number. It documents the measured purity (HPLC), confirmed identity (mass spectrometry), and screening results such as bacterial endotoxin. Because it is lot-specific, it lets you verify exactly what was tested for the material you received rather than relying on a generic product claim.
Compounds ship as a lyophilized powder in a sealed, tamper-evident vial, labelled with the lot number that matches its published Certificate of Analysis. Lyophilized material is stable at ambient temperature in transit, so no temperature-controlled shipping is used or required.
Store lyophilized vials at −20 °C for long-term storage. For short-term storage, 2–8 °C is appropriate. Keep vials sealed, protect from light and moisture, and avoid repeated temperature cycling. These are factual storage parameters for the researcher; follow your institution's protocols.
In-stock orders are processed and shipped the same day when placed before the daily cutoff. Every shipment includes carrier tracking and shipment protection, and your tracking number is emailed at dispatch so you can follow the order from our facility to delivery.

What the research community says
Lot-to-lot consistency is what kept us. The COAs match the HPLC traces we run in-house, so reproducing a prior experiment with a new lot is genuinely predictable.
The Certificate of Analysis covers what I actually need to see - mass spec for identity, HPLC for purity, and endotoxin screening. It's the difference between documentation and a sticker.
Batch-specific COAs and clean documentation make our internal review straightforward. Every lot maps back to a record we can file and audit.
We switched after running into purity issues with a previous supplier. The HPLC results here held up against our own analysis, lot after lot.
The price-to-quality ratio is hard to beat, and the bundle discounts make larger orders for a study budget workable without cutting corners on documentation.
Packaging was professional and secure, the vials arrived intact, and the lot documentation matched the order exactly - with carrier tracking from dispatch to delivery.
