Reference peptides for Guatemala City research groups

What the batch paperwork actually shows

Release testing covers HPLC purity, mass-spectrometry identity, appearance and residual moisture. Purity sits above 99% across the catalogue, and the chromatogram is part of the certificate rather than a claim printed next to it. You can ask for the batch certificate before ordering, which lets procurement in Guatemala City finish its checks first.

Reference material is stored lyophilised and only reaches Guatemala City in that state; reconstitution happens at your bench, under your protocol. Copies are re-sent whenever a lab needs them for its records. Where work is split between Guatemala City and another site, matched batches remove a common source of unexplained variance. Nothing on this page is a promise about outcomes; it describes handling, documentation and logistics for Guatemala City, Guatemala.

The legal position, stated plainly

Material is sold for laboratory research only, with that classification stated on the documentation. Batch numbers on the vial cap should match the certificate exactly — if they do not, stop and ask us before opening anything. No item is a medicinal product, and none is offered for use in or on a person or animal. Buyers in Guatemala are responsible for confirming that their intended research use complies with local rules before ordering.

Import rules for research reference material in Guatemala remain the buyer's responsibility to confirm before ordering. Parcels are documented for inspection rather than routed to avoid it. Nothing described here is a medicine, a treatment or a supplement — the material is in-vitro reference standard only.
