Other bioregulators that may support lupus management include Livagen for liver support (important given the hepatotoxicity of many lupus medications), Vilon for immune regulation, Ovagen for liver and GI support, Pancragen for pancreatic function, and Bronchogen for respiratory support in cases where lupus affects the lungs
Lyophilized vs liquid peptide stability Lyophilized (freeze-dried) powder: Most peptides sold in this form Moisture removed via freeze-drying Very stable when dry Can last years if stored properly Requires reconstitution before use Lyophilized stability: Freezer (-20C): 2-5+ years for most peptides Refrigerator (2-8C): 1-2 years typical Room temperature: Weeks to months (varies by peptide) Key factor: Keeping it DRY (moisture is enemy) Liquid (reconstituted) peptides: Peptide dissolved in water Much less stable than powder Water enables hydrolysis Bacterial contamination risk higher Limited shelf life Liquid stability: Refrigerated with bacteriostatic water: 28-30 days typical Refrigerated with sterile water: 5-7 days maximum Room temperature: Hours to 1-2 days only Frozen (reconstituted): DO NOT FREEZE liquid peptides Key principle: Keep peptides as dry powder until needed, then use reconstituted solution within recommended timeframe
