sore arm after b12 injection days Why do I feel worse

Some users do their injection immediately upon waking, then do fasted cardio before breakfast

Not for human consumption, nor medical, veterinary, or household uses

Take your hCG or sterile water out of the refrigerator 15 minutes beforehand so it hits room temperature before you inject it

Vitamin B12 is a crucial vitamin that your body requires but cannot produce

Methylmalonic acid and homocysteine levels provide accurate diagnosis when serum B12 falls between 200-400 picograms per milliliter (the gray zone where symptoms appear but standard tests show normal results)

Research shows that low B12 could influence fat metabolism because a lack of B12 may hinder your bodys ability to burn fat effectively, potentially leading to weight gain
