While many people get enough vitamin B12 from their diet, others may not absorb it efficiently or consume too little
I am a somewhat regular user and usually will use for 2 months and then cycle off for a month or the results I see seem to diminish
On the other hand, heavy drinking, weight loss surgery, and removing part of the stomach are some other reasons for the slow absorption of this vitamin
Plants contain B12 but not attached to a protein, so it is not bioavailable to humans in this state
When taken in injection form, you can experience a boost in energy, regulation of appetite and improved fat burning
The other option is for labs and researchers to buy from "research-use-only" vendors, who provide peptides with no prescription requirement, at a much lower cost
