TUDCA isn't optional for serious cycle support. Most brands skip it because it's expensive. Here's why that's a mistake.
What TUDCA actually is
Tauroursodeoxycholic acid is a bile acid derivative used clinically for cholestatic liver conditions. In the supplement world, it's the gold-standard liver support compound for cycle protocols.
Why most brands skip it
Cost. TUDCA wholesale is 20-30x the cost of milk thistle. To hit a £29.99 retail price point, brands either underdose it or skip it entirely.
When you need it
Any testosterone support protocol over 4 weeks. Any time you're stacking multiple compounds with overlapping hepatic metabolism. As baseline insurance during high-stress training cycles.
How to dose it
Standard supplement protocols use 100-500mg/day. We use 100mg in INVINCI-BULL, stacked with 500mg of milk thistle (silymarin 80%) for complementary mechanism.
