All peptides and HGH products sold on growthguys.com 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.

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.

We offer fast domestic shipping dispatched within Canada. Standard orders are processed within 24 hours and typically arrive within 2-3 business days.

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.

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.
