What are peptides?

Peptides are short chains of amino acids that act as signaling molecules in the body, supporting various biological functions such as recovery, metabolism, and cellular health. 

Are your peptides for human consumption?

No. All products sold by Premier Peptides are strictly intended for laboratory research use only and are not for human consumption.

Are your peptides tested for purity?

Yes. Every batch is third-party lab tested for purity and quality to ensure research-grade standards. COAs are available upon request. 

How should peptides be stored?

Lyophilized (powder) peptides should be stored in a cool, dry place or refrigerated. Once reconstituted, they should be refrigerated and used within a short period for best stability.  

Do you provide Certificates of Analysis (COA)?

COAs are available for most products, but not all batches have a COA. You can request one by emailing hello@premierpeptides.ca 

Where do you source your peptides from?

Our peptides are manufactured in Canada by certified laboratories that follow strict quality and safety protocols to ensure consistency and purity. 

How are orders shipped?

Orders are dropped off at GTA-GSM or Canada Post Monday–Friday. Orders placed before 2:00 PM ET typically ship the same business day. Orders after that ship the next business day. 

Do you offer free shipping?

Yes. Free shipping is automatically applied on orders over $300. No code is needed at checkout. 

Do you ship internationally?

Currently, Premier Peptides ships within Canada. We may expand tointernational regions in the future.  

What payment methods do you accept?

We accept Interac e-Transfer at checkout. Additional methods may be added in the future. 

How can I track my order?

Once your order ships, youʼll receive a tracking link via email. Tracking may initially show “label created” until our shipping partner physically picks up the package. 

What if my package is lost or delayed?

If tracking shows no delivery, contact us. Weʼll help file an inquiry with the carrier. Refunds or replacements are only issued once the investigation confirms loss.

What happens if my address is incorrect?

Customers are responsible for entering accurate shipping details. Returned packages due to incorrect addresses may be reshipped at the customerʼs expense.

Can I cancel or change my order?

Orders can only be changed or canceled before shipment. Once the order enters fulfillment after payment, it is final and cannot be refunded, even if it hasnʼt left the facility.

What is your refund policy?

Due to the nature of research chemicals, all sales are final. Only products damaged during transit or with a verified manufacturing defect reported within 72 hours may be considered for replacement. 

How do I contact customer support?

You can reach us anytime at hello@premierpeptides.ca. Responses typically take 24 hours on business days.

Are your products legal to purchase in Canada?

Yes. All products sold are legal for research purposes in Canada. Buyers must ensure compliance with local laws.  

Do you offer bulk or wholesale pricing?

Yes. Discounts are available for bulk ordersor recurring purchases. Email us for a custom quote. 

How are peptides reconstituted?

Reconstitution should only be performed by qualified researchers using bacteriostatic water or another suitable solvent under sterile conditions. 

Why choose Premier Peptides?

We combine scientific precision, purity verification, and fast Canadian shipping to ensure customers receive reliable research-grade products. 

What is the shelf life of lyophilized peptides?

When stored correctly in a cool, dry environment, most lyophilized peptides are stable for 12–24 months.

Can peptides be frozen?

Yes. Lyophilized peptides can be frozen for extended storage. Reconstituted peptides should not be frozen. 

Are your peptides sterile?

Most research-grade peptides are not sterile unless explicitly stated. Proper sterile technique should be used when handling. 

How long does shipping usually take?

Transit times are typically 3–7 business days within Canada, but delays can occur due to carrier issues. 

Can I split or combine vial sizes?

Vials may be split or condensed to match total purchased amount. For example, a 10mg order may be fulfilled as two 5mg vials. 

How are your peptides packaged?

All products are securely packaged to protect against moisture, temperature changes, and physical damage during shipping. 

Can I order on weekends?

Orders can be placed at any time, but fulfillment only occurs Monday–Friday during business hours.

Do you ship on holidays?

No. Orders are shipped on businessdays only, excluding federal holidays. 

What if my shipment is delayed due to customs?

Currently, we ship within Canada, so customs delays do not apply. International shipping may be supported in the future with applicable customs procedures. 

Are peptides sensitive to light?

Some peptides are light-sensitive. Lyophilized powders should be kept in originalpackaging away from direct sunlight.

Can peptides be reconstituted multiple times?

Reconstitution should only be performed once to maintain stability. Multiple reconstitutions can degrade peptide quality.  

How do I know my peptide batch is authentic?

Each batch has a unique batch number and can be verified with third-party lab testing or COA when available. 

What solvents are recommended for reconstitution?

Bacteriostatic water or sterile buffers are recommended. Avoid non-sterile solvents. 

How do I report a damaged product?

Email hello@premierpeptides.ca within 72 hours with photos and order details. Claims are reviewed at our discretion.

Yes, our research-grade peptides do not contain common allergens unless stated otherwise. 

Can I pre-order out-of-stock products?

We do not accept pre-orders. Items will be available once restocked. 

How should I handle peptide waste?

Dispose of peptides accordingto local laboratory waste protocols. Never pour chemicals down household drains. 

Are your products GMO-free?

All peptides are synthetic or recombinant as specified, and do not contain genetically modified organisms unless explicitly stated. 

Do you provide research guidance?

We provide general handling information only. No usage guidance for humans or animals is offered. 

Can I combine multiple orders for shipping?

Orders placed separately cannot be combined once payment is processed. 

Are there quantity limits per order?

Some products may have quantity restrictions to ensure compliance and stock availability.
