Pre-Workout Label Analyzer
Paste any pre-workout ingredient list. See which doses are research-effective, which are underdosed, and where a proprietary blend is hiding the real amounts.
One ingredient per line, with its dose. We never store what you paste.
Analysis
L-Citrulline
4 g · target 6 – 8 g
Pump and blood flow. Citrulline malate needs 6 to 8 g, pure citrulline at least 6 g.
Beta-Alanine
3.2 g · target 3.2 – 6.4 g
Causes skin tingling (paresthesia). Aftershock leaves it out on purpose, so no tingling.
Caffeine
320 mg · target 100 – 400 mg
Energy and focus. Above 400 mg per serving the risk of jitters and disrupted sleep rises.
L-Tyrosine
300 mg · target 0.5 – 2 g
Focus under stress. Common doses are 0.5 to 2 g, lower amounts are usually underdosed.
Proprietary Energy Blend
1.5 g

Frequently asked questions
How do I read a pre-workout label?
Check that every active ingredient lists its own dose in mg or g, and compare each to the research-effective dose. Watch for proprietary blends that hide individual amounts, underdosed "label dressing" added in tiny amounts, and beta-alanine, which causes the tingling many people mistake for potency.
What is a proprietary blend and why is it a problem?
A proprietary blend lists several ingredients under one total weight without telling you how much of each you get. It lets brands add a pinch of expensive ingredients and fill the rest with cheap ones. If a label hides doses, you cannot tell if it works.
Why does beta-alanine make you tingle?
Beta-alanine binds to nerve receptors under the skin and triggers paresthesia, a harmless tingling or prickling. It is not a sign the product is working. Aftershock leaves beta-alanine out on purpose, so you get the performance without the itch.
Is this analysis accurate?
It compares each dose to common research-effective ranges for healthy adults and flags anything below them or hidden in a blend. It is an educational guide, not medical advice, and it cannot see ingredient quality or sourcing.
