Quality Assurance
Lab Results
Every batch of every compound we carry is tested across 7 independent analytical panels at US-certified laboratories before release. Full COAs are published here — no summaries, no selective disclosure.
This is the Zenith standard. If it doesn't pass all 7, it doesn't ship.
Confirms exact molecular identity. Eliminates analog substitution — you get what's on the label.
TEST 03
Amino Acid Analysis
Sequence verification at the amino acid level. Critical for complex peptides.
TEST 04
Endotoxin / LAL
Limulus amebocyte lysate test for bacterial endotoxin contamination.
TEST 05
Sterility
Microbial contamination panel. Bacteria, yeast, mold — all screened.
TEST 06
Moisture Content
Water content analysis ensures accurate dosing weight and long-term vial stability.
TEST 07
Heavy Metals
Full heavy metal screen. Especially critical for compounds sourced internationally. A test most vendors skip.

Who We Are
Our Standard
Zenith Labs was built on a simple observation: the research peptide market rewards marketing over quality. Vendors sell on brand, not on proof. COAs get cherry-picked. Testing is minimal and opaque.
We built Zenith to change that. Every compound we carry passes 7 analytical tests at US-certified laboratories before it's listed for sale. Every COA is published in full. No exceptions, no summaries, no selective disclosure.
And we price below the market. Because rigorous QC and accessible pricing aren't mutually exclusive — they just require discipline.
01
Source Vetting
We evaluate manufacturers on production standards, consistency across multiple sample orders, and documentation quality before committing to any supply relationship.
02
7-Point Panel
HPLC, mass spectrometry, amino acid analysis, endotoxin, sterility, moisture content, and heavy metals. All seven. Every batch. No exceptions.
03
Full Disclosure
Every COA from every batch is published on this site. If a batch fails any test, it doesn't ship and we disclose that publicly. Trust is built on transparency.
04
Market Pricing
We believe the most tested compounds should also be the most accessible. We operate lean to beat market pricing on every product we carry — without cutting corners anywhere else.
Common Questions
FAQ
What does "research use only" mean? +
All products sold by Zenith Labs are intended strictly for in vitro laboratory research purposes. They are not approved by the FDA for human use, are not dietary supplements, and are not sold for any therapeutic application. By purchasing, you affirm that you are a qualified researcher and will use the compounds accordingly.
What labs do you use for testing? +
We use US-certified analytical laboratories for all 7 tests in our standard panel. Lab names and COA documents are published on our Lab Results page alongside every batch entry. We do not use overseas-only testing — all results are verifiable from US-accredited facilities.
Why do you test for heavy metals when others don't? +
Most compounds in this space are manufactured internationally. Heavy metal contamination — lead, arsenic, mercury, cadmium — is a real risk in the supply chain and is the test most vendors skip because of cost. We include it in our standard panel because we consider it non-negotiable.
What payment methods do you accept? +
We accept cryptocurrency (BTC, USDC), Zelle, and major credit/debit cards through our secure high-risk payment processor. Crypto orders receive a discount. Payment details are available at checkout.
How is shipping handled? +
All orders ship discreetly in unmarked packaging. Compounds are shipped as lyophilized powder in sealed vials. Domestic US shipping only. Tracking provided on all orders.
What if a batch fails testing? +
It doesn't ship. We publicly disclose failed batches on our Lab Results page. This has cost us inventory — we consider it a cost of doing business correctly. If a product you ordered is affected by a batch failure, you are notified immediately and offered a full refund or replacement.
How do you price below market with more testing? +
We operate with minimal overhead, batch our testing efficiently, and negotiate volume pricing with our lab partners. We don't spend on expensive ad channels or brand markup. The savings go to pricing, not margins.
