If the body properly uses B12, studies show it can stay in the body for up to five years
In my opinion, until we see these technologies backed up by good studies, consumers would be best served being directed towards a high quality oil in the re-esterified triglyceride form (like we list below)
I have been an OGF user since 2007 (began as MAX GXL user)
No published human case series has documented a causative link between exogenous thymosin beta-4 or TB-500 and new malignancy

These findings are consistent with previous studies suggesting that Mel and GSH may prevent structural damage in ovarian histoarchitecture by suppressing oxidative stress.10,11,15-18,21,22 Both Mel and GSH are key endogenous antioxidant molecules that neutralize free radicals and preserve tissue integrity by limiting oxidative stress-induced cellular damage.30,31 It has been previously reported that platinum-based chemotherapeutic agents such as carboplatin increase intracellular ROS production, thereby triggering lipid peroxidation (as indicated by elevated MDA levels), inflammatory responses (increased TNF- and IL-6), cellular damage, and apoptosis.2,7,8 In the current study, the increased immunoreactivity of Caspase-3 and NF-B, along with significantly elevated levels of TNF- and IL-6 in the CARB group, indicate that CARB may have simultaneously activated both apoptotic and inflammatory pathways
