// Frequently Asked
Answers, not adjectives.
Everything you might want to know — sourcing, testing, shipping, compliance.
01 Quality & Testing
Are your products third-party tested?
Where can I find COAs?
Every Certificate of Analysis is available in our public COA Library. You can also scan the QR code on any vial label to access its COA. No paywalls, no sign-up required.
Who tests your products?
We work with an independent Canadian third-party laboratory. Their identity is published on each COA. They use HPLC (High-Performance Liquid Chromatography) to verify purity and Mass Spectrometry to verify molecular identity.
What purity standard do you maintain?
≥98% purity on every compound. Verified independently. If a batch doesn’t meet that threshold, we don’t release it — period.
02 Ordering & Shipping
Where do you ship from?
All orders ship from Canada via Canada Post Xpresspost. Orders placed before 4PM ET ship same business day.
How long does shipping take?
Within Canada: 1–3 business days. To the United States: 5–10 business days. International: varies by destination and customs processing.
Do you ship internationally?
We ship to most countries where research compounds are legal to import. It is the buyer’s responsibility to verify local regulations before ordering.
What does your packaging look like?
Plain, discreet, unmarked Xpresspost packaging. No GREYGEM branding on the outer box. Tamper-evident interior packaging with batch verification stickers.
03 Products & Storage
How should I store my vials?
What is the shelf life?
Properly stored lyophilized peptides typically remain stable for 24+ months from the manufacturing date. Reconstituted peptides should be used within 30 days.
How do I reconstitute?
Use bacteriostatic water. Reconstitute slowly along the side of the vial — do not shake. Gently swirl to dissolve. Use our Calculator to determine your exact dilution ratio.
How can I check stock availability?
Stock status is shown in real-time on every product in the Catalog. Products marked “On Backorder” can still be ordered and will ship as soon as new inventory arrives.
04 Payment & Compliance
What payment methods do you accept?
All major credit cards (Visa, Mastercard, American Express) and Interac (Canada only). All transactions are processed securely.
Are your products legal?
GREYGEM products are sold strictly for laboratory research and educational purposes. They are not approved by Health Canada, the FDA, or any regulatory authority for human use, medical use, or therapeutic use.
Do you offer refunds?
All sales are final. Due to the sensitive nature of research compounds — cold chain integrity, tamper evidence, and safety standards — we cannot resell or restock returned product. If your order arrives damaged or incorrect, contact us within 7 days and we will make it right.
What does “research use only” mean?
05 Account & VIP
How does the VIP Club work?
VIP Club membership is $35/month and includes 10% off every order, free shipping on orders over $99, priority dispatch, and early access to new compounds. The membership pays for itself with regular ordering. You can join — or cancel — anytime from your account.
