I'm not working with Dr. Kaufman. But have been using 2 peptides: Thymosin Alpha & Thymosin Beta. I also started BPC-157 with them at the same time, but stopped it without any ill effects.
The peptides were HUGE for me. A total game changer. I was bed-bound for 6 months with extreme malaise, brain on fire feeling, and extreme irritability. I could barely do anything, basically only eat and use the bathroom.
The peptides got me from bedbound 20 hours/day to mostly homebound and able to run a few errands out of the house (1-2 hours out) per week. I also felt like a bit of my personality come back. And I noticed a change was fairly immediatly (for me at least) - 1-2 days. I still take them and never missed more than 1-2 doses (tho changed my dosing frequency, as I can now get by with less).
