ProSupps Hyde Nightmare Black Blue Berry is a high-stimulant pre-workout from ProSupps, built for lifters who already know how they handle stimulants and want full doses on the label rather than a blend. It sits in the pre-workout category, and each 444g tub holds 30 servings. Every scoop carries 300mg of tri-source caffeine alongside 4000mg of L-Citrulline, so you get a strong stimulant hit and a genuine pump dose in the same serve, at $56.95 a tub.
Caffeine is the backbone of any stimulant pre-workout, and ProSupps Hyde Nightmare Black Blue Berry builds its 300mg dose from three sources instead of one. Natural caffeine from Camellia sinensis and Coffea arabica sits alongside caffeine anhydrous, so the fast-absorbing anhydrous form supplies the initial lift while the plant-derived caffeine extends the curve. Caffeine works by blocking adenosine receptors in the brain, which is what keeps fatigue signals from landing mid-set.
The pump and endurance side of the formula runs on L-Citrulline and Beta-Alanine. L-Citrulline converts to L-arginine in the body and feeds nitric oxide production, which widens blood vessels and increases blood flow to working muscle during a set. Beta-Alanine takes a different route, raising muscle carnosine levels to buffer the acid that builds up as reps add up.
What separates ProSupps Hyde Nightmare Black Blue Berry from a lot of the pre-workouts on the shelf next to it is that ProSupps lists full doses rather than folding actives into a blend. A few details worth knowing before your first scoop:
At 30 servings per 444g tub, the cost per session holds up against smaller-dose competitors, and Black Blue Berry is one of three flavours in the ProSupps Hyde Nightmare range alongside Dragon Fruit and Orange Screamsicle.
Take one full scoop of ProSupps Hyde Nightmare Black Blue Berry with 300 to 400ml of water, 20 to 30 minutes before training. Because the 300mg caffeine dose sits at the strong end of the pre-workout category, earlier in the day is the safer window if you want it clear of your system by bedtime. On heavier training days, pairing it with a creatine dose before you train and a protein shake after covers both ends of the session.
Store the tub sealed, away from direct heat and moisture, and keep the scoop dry between uses so the powder doesn't clump.
Mix 1 scoop with 175 to 235ml (6 to 8 oz) of cold water and drink 15 to 30 minutes before training. Assess your tolerance first with half a scoop. Do not exceed 1 scoop in any 24-hour period and avoid other sources of caffeine. Not for use late in the evening.
Made for experienced trainers who want a strong, high-caffeine pre-workout for heavy lifting, hard conditioning or long sessions. If you train in the evening or are sensitive to stimulants, start with half a scoop and avoid taking it late in the day. It mixes clean and tastes good, so the only intense part of your session is the training.
Very. Each full scoop has 300mg of caffeine, roughly three cups of coffee, so it is built for experienced pre-workout users.
Yes. 4g of L-Citrulline supports nitric oxide and blood flow for fuller, longer-lasting pumps.
That harmless skin-tingling is from Beta-Alanine and is completely normal. It settles as your body adapts.
15 to 30 minutes before training. Because of the caffeine, keep it to earlier in the day.
Yes. ProSupps Hyde Nightmare Black Blue Berry pairs well with creatine, since neither ingredient competes with the other for uptake, and with a protein shake post-session for recovery. Just watch total caffeine if you're also taking a fat burner or another stimulant product that day, since this formula alone delivers 300mg of caffeine per scoop.
It can be, but go in eyes open: each scoop carries 300mg of caffeine, which is a strong dose for someone who hasn't used a high-stim pre-workout before. Kiwi lifters new to the category are better starting with a partial scoop to gauge tolerance before working up to the full 300mg serve.
Keep the tub sealed in a cool, dry cupboard rather than a bathroom or a spot that catches direct sun, which matters more in New Zealand's warmer regions over summer. Moisture is the main risk with any powder pre-workout, since it clumps the scoop and can affect how evenly the actives mix into your water.
Black Blue Berry is one of three flavours in the ProSupps Hyde Nightmare range, alongside Dragon Fruit and Orange Screamsicle. This listing covers Black Blue Berry specifically, including its 300mg tri-source caffeine and 4000mg L-Citrulline per scoop; if you're weighing up flavours, that comes down to personal taste rather than anything covered on this page.
