Analysis

A 2,000 mg L-proline serving supplies substantially more amino acid than the capsule products in this set. The isolated formula is well suited to users seeking targeted structural-protein support.

The simple delivery avoids proprietary blends and makes the active amount easy to track. No complementary cofactors are provided, so the formula remains focused rather than comprehensive.

The low serving cost is impressive for the amount supplied. It fits high-dose users who value dose flexibility, while capsule users may find the format less convenient.
