How it is supplied
Pre-filled research pensEvery compound arrives in one consistent, documented format — so what is on the certificate is exactly what is on your bench.
Sealed in the original box
Each pen ships in a tamper-evident carton printed with compound, content, lot number and retest date.
Pre-formulated sterile solution
Supplied ready-formulated, so there is no reconstitution step and no powder handling in the laboratory.
Refrigerated storage
Store at 2–8 °C, protected from light, in the original box. Stability data is available on request.

Format comparison
Engineered format vs. manual reconstitution
A sealed, pre-formulated pen removes the weighing, reconstitution and transfer steps of lyophilised vials — and every unit is traceable to its own batch certificate.
Documented from synthesis to delivery.
We publish chromatograms, not summaries. Every figure on a product page is traceable to a Certificate of Analysis you can open yourself.

Guide 01
How to read a Certificate of Analysis
A COA can show an impressive purity figure and still leave important questions unanswered. What to check line by line.
Guide 02
How to choose a research peptide supplier
Batch documentation, identity testing, cold-chain and traceability — a buyer’s checklist.
Guide 03
What does ≥99% HPLC purity actually mean?
“99% purity” looks straightforward. What the number measures, what it does not, and why identity testing matters.
Guide 04
Storage & stability of research peptides
Temperature, light and handling — how to keep material within specification until the retest date.
Delivery
Orders placed on business days are dispatched within 24 hours in insulated cold-chain packaging, tracked and insured, in a plain outer carton. Shipping is a flat $19 and free on orders over $250. There is no minimum order.
Shipping detailsQuality & handling
Products are held refrigerated at 2–8 °C until dispatch. Each batch is independently tested for purity (HPLC), identity (LC-MS) and endotoxin, and the certificate is published on the product page against the lot number printed on your box. Results can vary slightly between batches — that is why every lot has its own COA.

Product fine, took two days to get payment instructions
The product and packaging were both fine. My only issue was that payment instructions arrived two business days after placing the order, which pushed back dispatch. Documentation was accurate when it came.

Semaglutide 10 mg · Aug 2026Second order — consistent between lots
This is my second order of Glow. Lot number is different from my first, but the COA shows comparable results: ≥99% HPLC, identity confirmed by LC-MS. Free shipping on this order since I hit the threshold.

Glow 70 mg · Aug 2026Good product, shipping took 9 days to the US
Product itself was fine — pen was sealed, COA matched, no issues. Transit to North Carolina was 9 days, which is within the quoted estimate but on the longer end. Email support replied the same day I asked about tracking.
