Is Glow Stack from Lumera Labs HPLC verified?

Yes. Every Glow Stack lot Lumera Labs ships is HPLC-purity tested at synthesis and retested by Janoshik Analytical before release. The lot-specific Certificate of Analysis is published on the Lab Results page.

Is Glow Stack sold for human use?

No. Glow Stack is sold strictly as a laboratory reference standard for in-vitro research. It is not approved by Health Canada or the FDA for human use. Every order requires a research-use declaration.

How is Glow Stack shipped?

Glow Stack is lyophilized at synthesis, sealed under nitrogen, and shipped from Kelowna, BC at -20 C through cold-chain insulated packaging via Canada Post Xpresspost. Free shipping over $200 CAD. 24-48h transit Canada-wide.

Where can I see the COA for Glow Stack?

Each shipment includes a lot-specific Certificate of Analysis. The current lot's COA is also published at https://lumerapeptide.com/lab-results/ and can be cross-referenced by the batch number printed on each vial.

Overview

The Glow Stack is an investigational research blend provided as a co-lyophilized reference standard for cosmetic-axis pharmacology screens. Component identities, mass ratios, and HPLC purity per component are disclosed on the lot-specific Certificate of Analysis.

Each vial is lyophilized from acetate buffer, sealed under nitrogen, and shipped cold-chain at −20 °C from our Kelowna facility.

Research applications

Multi-mechanism dermal-research screens, comparative collagen/elastin synthesis assays, and reference-standard use for stack-based cosmetic pharmacology.

Sold for laboratory research only. This material is not a drug, food, or cosmetic and is not intended for diagnostic, therapeutic, or recreational use.

Reconstitution

Allow vial to reach room temperature before opening (≥ 20 minutes). Reconstitute with 1.0–2.5 mL of sterile bacteriostatic water (0.9% benzyl alcohol). Inject solvent slowly down the inner wall of the vial; do not direct stream onto the lyophilized cake.

Swirl gently for 30 seconds. Do not vortex. Allow to dissolve for 5 minutes; clarity should be complete with no visible particulates.

Storage after reconstitution

Reconstituted solution is stable for 28 days at 2–8 °C in original vial. For longer storage, aliquot into low-binding tubes and hold at −80 °C; avoid repeated freeze-thaw cycles. Discard if turbidity, color change, or particulate matter is observed.
