B1 Therapy...
My experience with TTFD started almost 2-1/2 years ago. healthunlocked.com/cure-par...
I was never able to find a sweet-spot and switched to B1 hcl oral. I have tried at least 3 times over the pass 24 months. The last time, I had a panic attack that lasted 6 hrs with 1/2 of a 5mg of Alinamin-F (Prescription drug in Japan and considered a supplement elsewhere).
FYI:
B1 (Thiamine) (g/mol): 265.4 C12H17N4OS+
TTFD (g/mol) : 398.5 C17H26N4O3S2
5 mg TTFD = 3.3 mg B1 (Thiamine)
1/2 tab = 1.664993726mg B1 (Thiamine)
RDA for men 1.2 mg B1 (Thiamine)
1/2 tab = 1.387494772 approximately 140% of RDA
