Nexaph
A US-shipping research storefront with an openly priced kit catalog and a dedicated lab portal whose active-batch reports largely resolve to Janoshik Analytical, including vendor mirror pages that disclose the tested compound by name in their own results.
Same formula for every vendor: verifiable testing evidence forms the backbone; third-party reviews adjust it within a bounded range. How scoring works →

Nexaph sells research-only singles and blends as fixed 10-vial kits, including house codes NXP-1P / NXP-2P / NXP-3P for semaglutide, tirzepatide, and retatrutide, plus a GHK-Cu/KPV beauty blend and a BPC-157/TB-500 blend. Its lab portal lists one active batch per catalog strength; most resolve through vendor mirror pages that name the compound directly in their own Mass/Purity results alongside Sterility, Endotoxin, and Heavy Metals panels, and the rest link straight to Janoshik.
Readers who want an openly priced kit catalog and lab reports that name the tested compound on their own results page, and who understand the identity behind the NXP house codes before ordering.
The public About page names the operating company as Shanghai Nexa Pharma Co, a Chinese company identity distinct from the US-facing shipping and contact presentation — worth knowing regardless of the US shipping/location signals. The catalog sells only fixed 10-vial kits (no single-vial pricing). NXP-1P / NXP-2P / NXP-3P are branded house codes for semaglutide, tirzepatide, and retatrutide; a separate NXP-ATP label has no public compound disclosure PeptideBenchmark could confirm and is excluded from the pricing board pending clearer vendor disclosure. Topical/cosmetic ampules and a non-peptide lipotropic injectable are excluded from the peptide-vial comparison set.

Checked August 7, 2026Public lab portal linking Janoshik Analytical reports
The lab portal publishes the full batch history for each catalog strength — the currently active certificate plus every previous version still retained — and PeptideBenchmark ingests all of them. 317 of 323 reports resolve to Janoshik Analytical either directly or through a vendor mirror page that discloses the tested compound by name along with Sterility, Endotoxin, and Heavy Metals results for the same batch; for the other 6 portal entries, the purity report carries no Janoshik task and key. PeptideBenchmark independently confirms the distinct Janoshik task/key routes at the laboratory and re-checks them on the normal trust cadence.
