Aim for a minimum of 20 to 30 grams per meal from whole food sources such as eggs, poultry, fish, legumes, or Greek yogurt

Each well was washed by adding 200 l PBS solution and then replaced with 200 l 4% paraformaldehyde solution, fixed at room temperature for 15 min and then removed

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
