FAQ

We get a lot of questions.

Here are the ones we hear most, answered straight.

View All FAQs
01 How do I know the lab results are real?
All peptides and HGH products sold on Growth Guys are lab tested by Janoshik to ensure maximum quality. With the exception of pharmaceutical Bacteriostatic Water, produced by Pfizer, if a product is not tested, we will not sell it. All products are paired with reports from Janoshik that you can personally view and match to the batch you have purchased and received.
02 What if a batch sells out?
When one batch sells out, the next goes through the full Janoshik testing process before it lists. We don’t carry stock that hasn’t been verified.
03 How fast does my order ship?
We offer fast domestic shipping dispatched within Canada. Standard orders are processed within 24 hours and typically arrive within 2–3 business days. Most orders ship the same business day, though delivery may take longer if there is a courier delay or you live in a remote or rural community.
04 Do I need anything else to use the peptide vials?
Yes, all peptides and HGH ship in lyophilized form and must be reconstituted with Pfizer Bacteriostatic Water prior to use. Bacteriostatic Water is sold separately. Please do not attempt to reconstitute our products with “underground” or off-brand bacteriostatic water.
05 Do you offer refunds or exchanges?
Please note that all sales are final. Due to the nature of our products and inventory, we are unable to accept returns. Product quality is independently assessed via 3rd party laboratory testing to ensure quality, and all purchases made via this website are done with the implied consent that you acknowledge and accept the empirical testing provided on each product page. In the event of dissatisfaction or quality concern, please contact us so that we can try to assist.

Research Peptides & HGH in Canada, Tested by Janoshik

Independent verification, complete transparency, and domestic shipping from within Canada.

Growth Guys Canada supplies research peptides, lyophilized HGH and oral research compounds to laboratories and researchers across Canada. Every batch we list is sent to Janoshik Analytical for independent testing before it goes on sale, and every certificate of analysis is published on our Lab Results page so you can match the report to the batch you receive.

Why third-party testing matters

Purity and mass are the two numbers that decide whether a research compound is fit for purpose. Our HPLC purity results average above 99% across peptide batches, and HGH kits are additionally tested for dimer content and endotoxin levels. If a batch is not tested, we do not sell it.

Domestic shipping, no customs exposure

All orders ship from within Canada via Canada Post — no border crossings, no customs seizures, no surprise delays. Most orders are dispatched the same business day with tracking, and orders over $350 ship free.
