A good fit for Comparing a flavoured caffeinated drink with separately declared amino acids and stimulant content.
- The checked Orange Cooler listing identifies 5 g amino acids and 100 mg caffeine per 9 g serving.
- The photographed 270 g tub states 30 servings, making the checked flavour and serving count clear.
- The ingredient list identifies green-tea and green-coffee extracts and lists the sweeteners separately.
Caffeine may disturb sleep or cause unwanted symptoms; flavour-specific ingredients and caffeine totals should be reviewed rather than treating the amino-acid blend as a protein replacement.

Ingredient timeframes describe the cited preparation; they do not establish a cycle for every finished formula.
Amino Energy
- On/off pattern
- No mandatory caffeine reset interval is established for this blend.
- Duration & evidence
- Use frequency depends on the actual caffeine amount, total daily exposure and sleep response; no standard number of on-weeks or off-weeks is supported.
- When to review
- Review before increasing scoops for a weaker perceived effect, or when sleep, anxiety or palpitations change.
- If reducing regular caffeine, gradual reduction can make withdrawal less unpleasant; the FDA does not specify a universal taper length.
- An occasional caffeine-free day is a preference, not proof that the whole blend becomes safe to use indefinitely.
