Score breakdown

Tap a module to see what it measures. A 0 can reflect missing disclosure, not just a negative result.

Dosage quality

7.8/10

Generally solid dosing

Checks whether labeled ingredient amounts fall within clinically studied ranges (not just regulatory minimums). Low/0 can reflect under-dosing or missing amounts (e.g., proprietary blends).

Multi-ingredient formulation analysis

Dose 7.8/10 · Bioavailability 5.3/10 · Coherence 0/10

This is a multi-ingredient product. The score reflects formulation quality, not efficacy for a specific health goal.

Score summary

Whey-protein: dose within clinically studied range (evidence A). The main limitation is that critical safety flag limits final score.

Strengths

Whey-protein: dose within clinically studied range (evidence A)
Arginine: dose within clinically studied range (evidence B)
Isoleucine: high-bioavailability form declared (L Isoleucine)

Weaknesses

Critical safety flag limits final score
Formula coherence is weak: diluted, decorative or overly complex

Final verdict

A strong option overall. Its main value comes from excipient quality, but the listed weaknesses are still worth checking before buying.
