Three weeks into Thymosin Alpha-1: Immune system observations

I started a protocol of 500mcg Thymosin Alpha-1 (TA1) daily about three weeks ago, prescribed by my clinic to help with chronic post-viral fatigue. I was a bit nervous given the regulatory shifts earlier this year, but my physician confirmed we are still operating within the current compounding guidelines. Honestly, the difference is subtle but noticeable. My morning brain fog has lifted significantly, and my Oura ring data shows my HRV has climbed from a baseline of 38ms to a steady 51ms over the last ten days. I haven't experienced any injection site reactions, just a slight flush for about 10 minutes post-injection. Has anyone else noticed a similar improvement in recovery metrics while on TA1? I'm curious if I should cycle this or if it's safe to continue for another month.
