Dietary and allergen information
Other ingredients on the label: Natural & Artificial Melon Flavours, Citric Acid, Sucralose, Silicon Dioxide, Tartrazine [E 102].
Facility statement on the label: produced in a facility that may also process ingredients containing milk, egg, soy, shellfish, fish, tree nuts, wheat, peanuts and sesame. This is a shared-facility statement, not a product “contains” allergen declaration unless the pack states otherwise.
Melon Flavours appear in Other Ingredients only. This is not used as the product flavour name because of the flavour conflict documented below.
How to use
- Mix 1 scoop with 180–250 ml water.
- Take approximately 30 minutes before training.
- Do not take within 4 hours of bedtime.
- Do not exceed 1 scoop per day.
Required clarification
Flavour conflict: The MUSKLE URL variant is Wild Berry (53858523087181). The supplied physical label front shows Tropical Rage. Other ingredients list Natural & Artificial Melon Flavours. These three flavour wordings are not treated as equivalent. This guide does not rename the Shopify flavour to Melon or Tropical Rage. Always verify the physical pack before use.
Net weight conflict: The supplied label states net weight 384 g (12.8 g × 30 servings). The Shopify size option reads “300 gram”. Some Shopify product media show different pack artwork (~398 g). These figures are not merged — the physical label remains leading for composition facts.
Caffeine: The Stim-Crazy complex lists component weights (caffeine anhydrous 350 mg; cocoa alkaloids 75 mg; dicaffeine malate 50 mg; green tea extract 20 mg (50% caffeine); yerba mate 20 mg; guarana 10 mg; green coffee 10 mg). Separately the label declares Contains caffeine — 400 mg of caffeine. Component weights are not summed or converted into caffeine totals. The 400 mg declaration and the component table are both shown; they are not interchangeable.
EGCG: The label states 0.24 mg EGCG per serving and a maximum of 800 mg EGCG per day. Do not use with other green tea products on the same day.
Barcode: Printed barcode 850006755370 has an invalid EAN-13 check digit (calculated check digit 6; printed 0). Shopify barcode for this variant is empty. Documented only — not corrected here.
Front-pack marketing phrases (Stim Crazy, supercharged, “7 types of caffeine”, performance wording) are recorded in the claim audit and are not published here as approved customer benefit claims.

Why is there a flavour conflict?

Why does net weight differ from Shopify?
The supplied label states 384 g net weight (12.8 g × 30). Shopify lists the size option as “300 gram”. Some Shopify media show different pack artwork weights. These are documented separately, not merged.
How should the powder be prepared?
Mix 1 scoop with 180–250 ml water. Take approximately 30 minutes before training. Do not take within 4 hours of bedtime. Do not exceed 1 scoop per day.
What is EGCG on the label?
The label states 0.24 mg EGCG per serving and warns not to exceed 800 mg EGCG per day. Do not use with other green tea products on the same day.
Are allergens declared as “contains” on this product?
The label includes a shared-facility statement (milk, egg, soy, shellfish, fish, tree nuts, wheat, peanuts, sesame). That is not automatically treated as a product “contains” allergen declaration. Always check the physical pack.
Who is the distributor?
The pack states: Rich Piana 5% Nutrition, Kemp House, 124 City Road, London EC1V 2NX, UK.
