Frequently Asked Questions

What makes this different from typical testosterone supplements?
This formula uses fully disclosed amounts, standardized extracts, and a focused formulation philosophy — no proprietary blends, no inflated label claims.
What’s the difference between 2, 3, and 4 capsules?
2 capsules is the Vitality dose — solid daily foundational support. 3 capsules is the Performance dose for elevated training phases. 4 capsules is Max Potency for a full-dose protocol. Start at 2 and assess before increasing.
Can I take this on its own?
Yes. This formula is engineered to work as a strong standalone foundation. Whether you start here or stack it with other Extra Pure Labs formulas is your choice.
