I did a cycle of SS31 with no noticable effects then ran motsc. The mots makes me crash HARD halfway through the day

After going down a rabbit hole, i suspect it has something to do with insufficient methylation donors due to a gene mutation (MTRR A66G). I've got some Methyl-B12, Betaine TMG, and bioactive Folate on the way and will try another cycle after giving the supplements some time to do their thing.
Who knows, switching from Cyano-B12 to Methyl-B12 may be the answer to my fatigue (and random peripheral nerve pain). I do have a doctors appointment soon so I'll be asking them to run some specific tests (homocysteine and folate) to see if all of that is even needed, but Swanson was having a sale and I got all those plus a few other supplements for under $30 with shipping.
