Mr. Hyde Signature V2
Our analysis — editorial take, not from the label
The V2 relaunch is a short, blend-free list — 3g citrulline, 2.5g creatine monohydrate, 2g beta-alanine, 1g betaine, 1g tyrosine and 200mg caffeine anhydrous in a 12.62g scoop. It is a cleaner and more moderate label than the older Nitrosigine/TeaCrine Mr. Hyde Signature that many retailers still list.

- 200mg caffeine per 1-scoop serving is roughly two cups of coffee.
- 2g beta-alanine may cause a harmless tingling (paresthesia) sensation.
Formulated for healthy adults — not intended for anyone under 18. Performance studies use roughly 3–6 mg of caffeine per kg of body weight, which puts 200 mg at the studied amount for a 33–67 kg adult. Full health & safety notes
Product details
Where this label sits
ProSupps Mr. Hyde Signature V2 sits in the moderate stim tier of the Scoop Sense pre-workout database, which spans 0–400 mg of caffeine per serving. Every active ingredient on the panel is listed with its own dose — nothing is hidden inside a blend total. It runs 30 servings per container at the full labeled serving. Everything on this page comes from the manufacturer's supplement facts panel as of July 2026 — never from the marketing page.
Key ingredients & studied doses
- L-Citrulline · 3 g. Below the 6-8g citrulline malate range used in most pump-focused studies, but a moderate dose of straight L-citrulline.
- Creatine Monohydrate · 2.5 g. Close to the 3g/day maintenance dose used in creatine research; consistent daily use matters more than pre-workout timing for creatine's effects.
- Beta-Alanine · 2 g. At the low end of the 3.2-6.4g/day range shown to raise muscle carnosine, but still enough to cause tingling for many users.
- Betaine Anhydrous · 1 g. Below the 2.5g dose used in most published betaine power-output studies.
Flavors & sweetener
Four flavors (Blue Razz, Fruit Punch, Pixie Dust, Watermelon) sweetened with sucralose and acesulfame potassium; color comes from blue spirulina extract, beet root powder, or fruit and vegetable juice depending on flavor, not synthetic dyes.

This label against the research
How we evaluate labelsEach bar shows the amount commonly used in published human research, and where this label's dose falls against it. Research amounts are context, not a recommendation — they are not doses, and nothing here is medical advice.

Citrulline3 g
50% of the low end of the studied range0studied range 6 g–8 g10 g
Studies use about 6 g of pure L-citrulline, or 8 g of citrulline malate — which is about 5.3 g of citrulline at the usual 2:1 ratio, and closer to 4 g if the label is 1:1.

-
Creatine2.5 g

Maintenance dosing in the research is 3–5 g a day of monohydrate, every day, not only on training days.

Beta-alanine2 g

Studied as a daily loading protocol of 3.2–6.4 g taken for four weeks or longer. A single serving below that range still counts toward the daily total, but one scoop is not a studied dose on its own.

-
Betaine1 g
40% of the low end of the studied range0studied range 2.5 g3.5 g
Trials run from 1.25 g to 5 g a day; 2.5 g, usually split into two doses, is the amount most of them use.

Caffeine200 mg
At or above the studied amount0studied range 200 mg–400 mg450 mg
Performance studies most often use 3–6 mg per kg of body weight, which works out to roughly 200–400 mg for most adults. The FDA cites 400 mg a day as an amount not generally associated with negative effects in healthy adults.
