“Bay has become my go-to source in Canada. Caps are tight, vials are properly labelled, and the shipping is consistently 2-3 days domestic. Bloods reflect the dose on the label.”

“Tried three other Canadian sources before settling here. Pricing on BPC-157 / TB-500 blend is hard to beat. Customer service actually responds in under a few hours.”

“Honestly the cleanest peptides I have sourced in Canada. The lyo cake looks textbook. Pricing on the GLP-1 line is the best I have seen north of the border.”
