Historical formula review. This article examines the GNC AMP Amplified Focus version described in our archive. The preserved ingredient table and images are archival, not a verified current shopping or dosing guide. This review does not establish present prices, stock or equivalence between product versions.

A cognitive/sports-positioned tablet with caffeine and lutein
The archived AMP formula listed choline, tyrosine, rhodiola, bacopa, theacrine, phosphatidylserine, coffee fruit concentrate, caffeine 100 mg, lutein and huperzine A. Its choline entry specified choline as choline bitartrate; that differs from assuming the number is raw choline-bitartrate weight.
Formula assessment
The original review expected both cognitive and muscular performance based on the product’s positioning, then dismissed parts of the formula from ingredient preference alone. Neither brand category nor use in sports establishes those endpoints. The coffee-fruit entry should also remain distinct from the separately listed caffeine rather than being counted as another known caffeine amount.


Ingredient table retained from the original review
The table records the original article’s ingredient names and quantities. It is a historical transcription, not independent testing. Original daily-value percentages are omitted where transcribed because they can be outdated or inconsistent; percentage standardisations attached to ingredients are retained. It should not be used to calculate a dose or substitute for an authenticated label.

Revised conclusion
This historical product is useful for examining how a disclosed mixed formula was marketed across mental and physical performance. It does not establish muscle benefit, legal suitability in every setting or inferiority merely because it uses choline bitartrate.
The former rating, price-based recommendation and unverified personal-experience claims have been removed. Ingredient studies, marketing mechanisms and a review of a label are different forms of information. None alone establishes how the complete product performs. Before assessing a later version, identify the exact manufacturer label, serving size, quantities and warnings; do not transfer old directions or conclusions between formulas.
