Natural testosterone supplements work best on a structured cycle, not continuous use. Here's the protocol.
Why cycle at all
Continuous use of any testosterone-modulating supplement risks receptor downregulation and adaptation. Cycling preserves response and builds in natural recovery windows.
The standard 8-12 week protocol
8-12 weeks on, 4 weeks off. Bloodwork before week 1 and after week 12 is the only honest evaluation. Run the full Stampede during the on cycle.
Why INVINCI-BULL belongs in every cycle over 4 weeks
TUDCA + DIM + NAC + milk thistle is the protective infrastructure. Liver support, estrogen modulation, glutathione recycling. The brands that don't sell this either don't believe in their product or don't care.
What to do during off-cycle
Maintain training. Maintain sleep and nutrition. Continue D3, zinc, magnesium baseline. Drop the cycle stack. Re-test bloodwork before the next cycle starts.
