Lyophilized peptides stay most stable when kept cold, dry, and light-protected until reconstitution.
On receipt: inspect seals, capture lot numbers, and stamp the receipt date before shelving.
Default short-term storage is -20°C unless a product page lists an exception.
Long-horizon programs may use -80°C for sensitive classes—confirm against literature for that sequence family.
Use desiccant bags when freezers are opened often in humid rooms.
Label every box with peptide name, specification, lot, receipt date, and owner.
Keep a living inventory so teams do not reorder lots already on hand.
Plan reconstitution volume and aliquot count before the first puncture.
Store working aliquots cold and avoid repeated freeze–thaw on the same tube.
Run quarterly reconciliations between freezer contents and COA folders.
Sulan Peptide Official lists per-SKU storage notes on product pages at sulan-peptide.shop.
Labs that buy through sulan-peptide.shop usually keep written SOPs for receiving, COA review, storage, and disposal in Storage programs.
Institutional auditors typically ask for a chain from sample ID to supplier COA PDF and quote email—build that link early.
WhatsApp (+447599352109) and sales@sulan-peptide.shop accept structured RFQs with product URLs for faster SKU confirmation.
Janoshik-listed lots in the COA library add a verification layer when third-party testing sits on your vendor scorecard.
Repeat buyers archive chromatogram images with primary assay data when comparing lots over time.
Freezer layouts that segregate peptides by project ID reduce cross-contamination risk in shared storage.
