  2. One capsule works for me when...

    Great product when used with a time released lower mg b12 product. One capsule gives me a full day of energy to do the cleaning or yard work or whatever I want without tiring. No need for additional caps. This keeps my head clear which is what I really needed.

  4. stacker 2 b12 capsules,

    I must say I didn’t think this product worked. I tell you the first day I didn’t notice anything ,but that second day .I notice how I energized I felt, my appetite was not shooting through the roof and no cravings. which is a plus for me. Basically I wanted more water to drink and usually after meals I want something sweet to eat. Since I started taking the STACKER B12 I am hardly ever hungry .

  6. do NOT take if u have ADHD

    I have ADHD and I took one and my god it just makes me super anxious and sick feeling. I didn’t take anything with it. I then learned that if you have ADHD, these can have adverse effects.
