PTLabs pTLabs sells loaded pens, refills, vials and oral peptides (Retatrutide, Tirzepatide, Tesamorelin) with GBP pricing, saying it ships 'directly from our UK lab'. Janoshik appears on the product pen photos and labels rather than as a text claim with a working verify link, so there is no per-batch certificate we can independently check.
The Peptide Watch benchmarks every vendor on the same compound, BPC-157, the most common research peptide, as £ per milligram, so prices are directly comparable across all providers. No public BPC-157 price feed was available for this vendor at audit.
