Our read on Hangzhou Qihang Xingcheng
1 of Hangzhou Qihang Xingcheng's 2 graded samples passed (50%), and 100% of all samples were sent in by buyers rather than by the shop.
When a sample failed, the most common reason was no purity figure on the certificate (1 time).
1 sample failed identity, meaning the lab could not confirm the vial held the labelled peptide.
When and how Hangzhou Qihang Xingcheng was tested
