HYDE is a ProSupps product family, and the full version name matters. Signature, Nightmare and Xtreme have different formulas. A caffeine figure from an older Mr. Hyde review should not be applied to every tub carrying the HYDE name.
Current HYDE versions at a glance
- Mr. HYDE Signature V2: The 30-serving label lists 200 mg caffeine, 3 g L-citrulline, 2.5 g creatine monohydrate, 2 g beta-alanine, 1 g betaine and 1 g L-tyrosine per 12.62 g scoop. Its separate two-scoop column doubles those amounts, including caffeine to 400 mg. Official product page.
- Mr. HYDE Nightmare V2: ProSupps describes a 300 mg caffeine total from three sources, with L-citrulline, beta-alanine, acetyl-L-carnitine HCl, alpha-GPC and L-theanine. The 300 mg figure is the combined caffeine amount, not 300 mg from each source. Official product page.
- Mr. HYDE Xtreme V2: Its displayed 30-serving facts panel lists 400 mg caffeine anhydrous per 14.36 g scoop, plus methylliberine and yohimbe/yohimbine-related ingredients. The panel also shows 3.2 g beta-alanine, 3 g L-citrulline and 2.5 g creatine monohydrate.
An Xtreme caffeine mismatch worth checking
At the time of review, the Xtreme webpage still stated 378 mg caffeine in its warning, while its linked facts image stated 400 mg. Its advertised 462.5 mg stimulant-matrix weight is not the caffeine amount. These conflicting figures should be clarified with ProSupps for the specific flavor and lot before use; this guide does not assume the lower number is correct.
How to make a fair comparison
Compare the same portion: one Signature scoop versus two Signature scoops is a substantially different purchase and caffeine decision. Record the powder weight, caffeine, creatine and number of usable portions before comparing prices. A stronger sensation is not evidence of better training results.
FDA caffeine guidance discusses 400 mg per day for most adults, not a personal target or a guarantee that one concentrated serving is suitable. Count every caffeine source. Follow the actual container’s restrictions, and do not add caffeine to resolve an underwhelming workout.
This is a manufacturer-label comparison. No hands-on flavor test, independent purity test or claim that the versions produce equivalent results is implied.
