Liquid Solutions 101: How to Figure Out Your Research Dosing (mg/mL)
A lot of you are used to reconstituting lyophilized (freeze-dried) peptides, so when you order a pre-made liquid solution like Glutathione 200mg/mL, the dosing math can feel a bit different. Let me break it down simple. The Basics: Glutathione 200mg/mL (20mL Total) This one's straightforward. You have 200mg of Glutathione per 1mL of solution. Since 100 units on an insulin syringe = 1mL, here's your dosing breakdown: - 25 units = 0.25mL = 50mg - 50 units = 0.50mL = 100mg - 75 units = 0.75mL = 150mg - 100 units = 1.00mL = 200mg Easy math: just take the units, divide by 100, then multiply by 200mg. At 100 units (200mg) per day, your 20mL vial lasts 20 days. At 50 units (100mg) per day, you get 40 days out of it. The More Complicated Example: NAD+/Carnitine Amino Blend (20mL) Now let's look at a multi-ingredient blend. Same concept, just more components to track. What's in each mL: - L-Methionine: 10mg/mL - L-Inositol: 50mg/mL - L-Choline: 50mg/mL - L-Carnitine: 250mg/mL - Vitamin B12: 500mcg/mL - Vitamin B6: 25mg/mL - NAD+: 20mg/mL Here's what you get at each dose: 25 units (0.25mL): Methionine 2.5mg | Inositol 12.5mg | Choline 12.5mg | Carnitine 62.5mg | B12 125mcg | B6 6.25mg | NAD+ 5mg 50 units (0.50mL): Methionine 5mg | Inositol 25mg | Choline 25mg | Carnitine 125mg | B12 250mcg | B6 12.5mg | NAD+ 10mg 75 units (0.75mL): Methionine 7.5mg | Inositol 37.5mg | Choline 37.5mg | Carnitine 187.5mg | B12 375mcg | B6 18.75mg | NAD+ 15mg 100 units (1.00mL): Methionine 10mg | Inositol 50mg | Choline 50mg | Carnitine 250mg | B12 500mcg | B6 25mg | NAD+ 20mg The formula: (units ÷ 100) × mg/mL concentration = your dose So if you're doing 50 units and want to know your NAD+ dose: (50 ÷ 100) × 20mg = 10mg NAD+ Storage & Shelf Life: The Question Everyone Asks "How long are these good for after opening?" These liquid solutions typically contain stabilizers that keep them viable at room temperature. Here's my approach: After first use, I go 30-45 days max.
