Light Protection Lyophilised IGF-1 LR3 should be stored in light-protected containers: Use original amber or opaque vials provided by the supplier Store vials in a dark cupboard or drawer within the refrigerator Do not expose vials to direct sunlight or bright artificial light If transferring to secondary containers, use opaque, UV-protective vials Light exposure can accelerate peptide degradation through photochemical reactions
Guideline 6: Special Population Considerations When figuring out B12 injection dosages and how often to give them, special groups need special care
Toxic solvent residues DMF (dimethylformamide) Known liver toxin Associated with reproductive toxicity Must be removed to extremely low limits in GMP drugs DCM (dichloromethane / methylene chloride) Probable human carcinogen Central nervous system depressant Dangerous even in small amounts if injected TFA (trifluoroacetic acid) Corrosive Can remain in peptides as unmeasured TFA salt Pharmaceutical products often convert TFA salts to safer counterions Without validated HPLC, mass spectrometry, and residual solvent testing, patients may be injected with harmful chemical contaminants
