Identity
MASS MATCH ±0.5 Da
Mass-spec fingerprint match to confirm we're shipping what's on the label.
HOW IT WORKS
Every batch tested before it's offered for sale.
Six vials from every batch are pulled at random and run through an independent lab's 8-point test panel. The signed COA is published to a public library, and every vial label carries the batch result plus a QR code that opens that COA directly — so there's never a mix-up about which result belongs to which vial.
The 8-point test panel.
This is what an independent lab certifies on every batch. The spec column is the gate — if a result fails, the lot doesn't leave the warehouse.
Purity
MEETS COMPOUND SPEC
HPLC quantification against the published reference standard for the compound. Below spec doesn't ship.
Net Content
±10% OF LABEL
Verified weight per vial. No under-fills, no surprises.
Conformity
100% PASS
Visual and physical inspection against the spec sheet.
Heavy Metals
<10 PPM
ICP-MS screen for lead, cadmium, mercury, and arsenic.
Endotoxins
<0.5 EU/mg
LAL endotoxin testing on every randomly-selected vial.
Sterility
USP <71> PASS
Sterility validation per USP <71> standards.
Fentanyl screen
NOT DETECTED
Cross-contamination screen to rule out fentanyl traces — non-negotiable.
From order to bench.
- 01
Order placed
Order hits the US warehouse before 2 PM MT — same-day pick. After 2 PM MT it goes out next business day.
- 02
Pulled from cold storage, labeled with the data
Every vial is pulled from temperature-controlled storage and labeled with the batch's purity result and a QR code that opens the signed COA directly. Lyophilized powder is stable at normal shipping temperatures — no cold packs needed in transit.
- 03
Tracked delivery
You get the tracking number the moment the carrier scans the label. Typical US delivery: 1–3 business days.

Testing & COAs
- What is a Certificate of Analysis (COA)?
- A COA is a document signed by an independent testing lab that confirms a specific batch passed identity, purity, and contamination tests. Every lot Glacier ships has one — published to a public library, traceable by lot number.
- Who tests Glacier's batches?
- We rotate testing across three accredited independent labs: Kovers, ILS Labs, and Freedom Diagnostics. None of our testing is done in-house — the labs that sign the COA are the labs that ran the panel.
- What happens if a lot fails purity?
- It doesn't ship. Every batch is tested by HPLC against the published reference standard for that compound and must meet or exceed accepted purity guidelines. If a result falls below the spec, the entire lot is rejected — no partial discount, no 'close enough.'
- How do I verify a lot number?
- Two ways. (1) Scan the QR code on the vial label — it opens the signed COA for that exact batch. (2) Open the COA library and search by lot. Either path shows the test panel results, the independent lab's signature, and the date the batch was qualified.
- Why HPLC instead of just mass spec?
- Mass spectrometry confirms identity — that the molecule is what the label claims. HPLC quantifies purity — how much of the sample is that molecule versus related impurities. Both are needed: identity tells you what it is, purity tells you how clean it is. We run identity by MS and purity by HPLC on every batch.
- Why do some COAs show purity above 100%?
- That's a quirk of how purity is calculated against a reference standard, not a real value above 100%. When a sample is slightly cleaner than the reference used to calibrate the instrument, the math reports >100%. The honest interpretation: the sample is at or near the reference standard's purity. We publish the raw number rather than rounding it down so the COA matches what the lab signed.
Regulatory & Intended Use
- Are these for human use?
- No. Glacier products are sold strictly for in-vitro laboratory research use. They are not intended for human or veterinary use. By purchasing you confirm you are a qualified researcher operating within applicable laws.
- Do you provide reconstitution or dosing guidance?
- No. As a research-use-only supplier we do not provide reconstitution, dosing, administration, or handling instructions. Researchers are responsible for designing their own protocols in accordance with their institution and applicable regulations.
- Do I need a license to order?
- Glacier sells exclusively to qualified researchers, institutions, and laboratories purchasing for in-vitro research. By placing an order you confirm you meet those criteria. We may request additional verification for certain compounds or order volumes.
Storage & Shelf Life
- Do products need to be shipped cold?
- No. Glacier products are lyophilized powders, which are extremely stable across normal shipping temperatures. We store everything in temperature-controlled inventory before packing, but the powder itself ships fine at ambient temperatures — no cold packs, no insulated mailers.
- How should the lyophilized powder be stored?
- Sealed lyophilized vials are stable at controlled room temperature for short-term storage and in a standard laboratory freezer for long-term storage. Keep vials sealed, protected from light, and away from moisture until use. Specific storage guidance is for the receiving lab to determine based on its own protocols.
- What is the shelf life of a sealed vial?
- Sealed lyophilized vials remain stable for years when stored frozen, and for months at controlled room temperature when kept in a dark, dry space. Shelf life is a function of storage conditions, not a date stamped on the COA.
Shipping & Tracking
- How long does shipping take?
- Orders placed before 2 PM MT ship the same business day from a US warehouse. Domestic delivery is typically 1–3 business days. Tracking updates the moment the carrier scans the label.
- Do you ship internationally?
- At this time Glacier ships within the United States only. International availability may expand later — if it does, it will be announced on the storefront, not by special request.
- What carriers do you use?
- FedEx and UPS for express services to the continental US. USPS is typically used for Puerto Rico shipments. The tracking number provided in your shipment email is the authoritative source for carrier and delivery updates.
- What if my package is lost or arrives damaged?
- We always recommend contacting the carrier first — they hold the package and the claim record. Beyond that, resolution depends on whether shipping protection was added at checkout: protected orders are handled through the protection provider, and unprotected orders are handled per our standard policies. Reach out with your order number and we'll point you to the right path.
Ordering & Payment
- What payment methods do you accept?
- Major credit and debit cards (Visa, Mastercard, American Express, Discover), Zelle, ACH bank transfer, and cryptocurrency. Payment options are presented at checkout based on order details.
- Is my payment information secure?
- Yes. Card payments are processed through a PCI-compliant payment processor — Glacier does not store full card numbers on its servers. ACH and crypto payment details are handled through their respective processors with the same standards.
Returns, Refunds & Cancellations
- Can I cancel or modify an order after it's placed?
- Cancellation and modification eligibility depends on order status at the time of the request. Please review our Terms of Service and Refund Policy for the specifics.
- What is your return policy?
- Returns and refunds are handled per our published policies. Please review the Refund Policy and Terms of Service before requesting a return.
