Tier 1 — Identity & Purity

Is it real, and is it pure? Adds a co-injection against a characterised standard so identity is confirmed rather than inferred from retention time alone.

Turnaround: 7–10 business days

Includes:

  • Everything in Screening
  • Co-injection confirmed identity
  • Higher-confidence impurity profile
  • Certificate of Analysis
Sample requirements
Minimum:
2 mg
Preferred:
5 mg
Accepted form:
Lyophilized powder or solution
Please make sure to ship dry in a sealed vial. If in solution, provide concentration and solvent details.

Tier 2 — Injectable Screening

Everything needed to screen a peptide for injectable use — chemistry plus safety. Includes endotoxin, heavy metals, and bioburden on top of full identity and purity.

Turnaround: 7–10 business days

Includes:

  • Everything in Tier 1
  • Endotoxin — USP <85> (LAL)
  • Heavy metals — ICP-MS
  • Bioburden — USP <61>
  • Injectable-screening Certificate of Analysis
Sample requirements
Minimum:
10 mg
Preferred:
15–20 mg
Accepted form:
Lyophilized powder (preferred) or sterile solution
Sample must be handled aseptically. Use depyrogenated vials. Do not use tap water for reconstitution.
