Notes

Prague-based lab widely treated as the reference option for research-peptide testing. Re-checked September 2026: the task-number and unique-key verification portal is live and the leadership team is unchanged. The February 2026 security incident exposed customer order and shipping data, not analytical instruments or the integrity of issued certificates, so previously issued COAs that resolve against the portal remain meaningful. Operating since roughly 2012-2013, formally incorporated in Czechia in 2022.
