Vitamin B12 is essential for supporting oxygen transport throughout the body by aiding in red blood cell production
Specialists understand proper protocols and monitoring requirements
Pernicious anaemia is caused by your immune system preventing your stomach and gut from absorbing B12 from your food
Managing combined side effects Expect amplified GI effects: Both peptides slow gastric emptying Synergistic nausea (not just additive) Constipation very common Weeks 9-16 most challenging Nausea management protocol: Prevention from day 1 (ginger, small meals) Prescription anti-nausea (Zofran) essential Liquid nutrition if needed Slower titration if poorly tolerated Constipation prevention: 80-100 oz water daily Fiber 25-30g daily Magnesium citrate 300-500mg nightly MiraLAX as needed Nutrition maintenance: Protein shakes 2-3 daily (30-40g each) Target 60-80g protein minimum Multivitamin daily B12 supplementation When to reduce doses: Severe persistent nausea despite management Unable to maintain adequate nutrition Vomiting frequently Quality of life severely impacted See our common peptide mistakes beginners make to avoid errors

Preventing Oxidation and Moisture Contamination Minimize Air Exposure: Limit the time peptide containers are open to reduce oxidation, especially for peptides containing cysteine (C), methionine (M), or tryptophan (W), which are prone to air oxidation
It helps maintain a healthy nervous system and is also involved in the production of red blood cells
