Start with the exact HYDE version
HYDE Nightmare is a ProSupps pre-workout. The current U.S. Mr. Hyde Nightmare V2 page shows a 300 mg total-caffeine formula. HYDE is a product family, so a number from an older Nightmare tub, a different HYDE product or an international listing should not be substituted for this panel.
This guide uses the manufacturer’s current 30-serving label and Jawbreaker packshot. The facts panel specifies one 13.26 g scoop. A flavor or packaging revision can change the serving weight and other ingredients, so the physical container remains essential.
What the current label contains
- 6,000 mg L-citrulline
- 3,200 mg beta-alanine
- 250 mg acetyl L-carnitine HCl
- 100 mg alpha-GPC and 100 mg L-theanine
- 300 mg caffeine in total
- 250 mg Himalayan rock salt, with 80 mg sodium declared
The caffeine total comes from 125 mg tea-derived caffeine, 100 mg caffeine anhydrous and 75 mg coffee-derived caffeine. These add up to 300 mg; they are not three separate 300 mg doses. Conversely, plant-derived caffeine still contributes to the total stimulant intake.
Read the instructions before stacking
ProSupps directs users to mix one scoop with 6–8 ounces of water before training and assess tolerance with half a scoop on first use. The warning says not to combine Nightmare with other caffeine or stimulant products and not to consume it within four hours of bedtime. Read the full adult-use and health warnings before deciding whether to use it.
Do not interpret “tri-source” as a promise that stimulation will feel smoother, last a predictable number of hours or avoid jitters. Those experiences vary, and this article does not report a personal product test.
A better comparison checklist
Compare the exact V2 formula, intended serving and final cost per serving. Check flavor-specific sweeteners and colors when those matter to you. If a seller shows a different caffeine number, ask which version will actually ship before purchase.
For tested athletes, marketing badges should prompt a check of the relevant certification directory and exact product or batch, rather than an assumption of zero risk. A label-based review can establish declared quantities and warnings; it cannot independently certify purity, predict results or guarantee suitability for every athlete.
