8 weeks for strength and collagen; 90 days for testosterone

Why it works

A complex natural mixture rather than a compound, with two fractions credited. Fulvic acid acts as an antioxidant and as a carrier shuttling minerals into cells, and in laboratory work blocks the self-clumping of tau protein. The pigment molecules alongside it are proposed to work as electron reservoirs that regenerate CoQ10, which is the mechanistic route behind the energy claims.

Where it fits

Shilajit is a move in 2 protocols. Each one opens the plan it sits in.
