$249.00
Research Use Only

The complete Wilson's Temperature Syndrome T3+T2 protocol kit. Includes 2x SRT3+T2-15 and 2x SRT3+T2-45. Each tablet contains T3 and 3,5-T2 in a 1:1 mcg ratio. The two strengths cover the full titration range: a 15/15 tablet divides to approximate 7.5/7.5, a 45/45 divides to approximate 22.5/22.5, and two 45/45 tablets give 90/90. Designed for cyclic titration protocols that address both the T4->T3 conversion problem (via the T3 component) and the often-overlooked T3->T2 conversion problem (via the T2 component).

For anyone working through stubborn thyroid issues, the difference a clean, sustained T3 profile makes is night and day - I've seen it in my own work and in everyone who follows the protocol.

Honestly, I don't know where else you'd find slow-release T3 at this quality. It's become something I won't go without.
