I tried it (Magtein) for a long period of time. Also Magnesium L-Lactate Dihydrate with zero perceivable benefits. Both were taken for a few years at least. How dumb was I to keep taking something that didn't help in any way? Very dumb. Another Datbtrue hype job. I also remember his claim for Niagen, IGF LR1 (only his... er.. Tom's.. of course), and MitoQ. Guess what all three of those did for me?
ZERO.
I think a lot of this shit is straight up placebo, including a lot of the healing peptides like BPC and TB. Problem is unless someone has a time machine, we can't have a control group of ourselves. Even GH to a great degree. Yea, I said it. The only thing that has ever consistently done anything is AAS and MT2. At one time, I was taking over $800/month in supplements. I have experimented with a lot. 51 different supplements per day at the peak. $800/month = jack shit in results.
