Performance Mass Stack
- Four mass-phase staples in one box — Mutant Mass 5 lb gainer, creatine, a pre-workout and Tongkat Ali capsules.
- Built for a bulking block — calories and protein to hit a surplus, plus creatine for strength and power during hard training.
- Priced below buying the four separately — a calorie-surplus stack, not a weight-loss product.
The Performance Mass Stack is a four-product mass-gaining bundle put together by Xplosiv in New Zealand. It pairs Mutant Mass 5 lb (a high-calorie gainer) with Swoleys Creatine Monohydrate Gummies, a MuscleTech EuphoriQ pre-workout and NoWhey Tongkat Ali capsules — four everyday training staples in one box, priced below the combined cost of buying them separately.
Four staples for a serious bulking block
One box: a 5 lb high-calorie gainer, creatine, a pre-workout and a botanical capsule — everything you need to fuel a mass phase alongside hard training.
Four products, one purchase
- Mutant Mass — 5 lb. A high-calorie mass gainer that provides protein and carbohydrate calories to help you reach a daily energy surplus during a mass-gaining phase.
- Swoleys Creatine Monohydrate Gummies — 12 serves. Creatine monohydrate in a chewable format; creatine supports strength, power output and performance during high-intensity training.
- MuscleTech EuphoriQ Pre-Workout — 20 serves (Icy Snow Cone). A stimulant pre-workout for energy and focus before a session. Best before 03/2026.
- NoWhey Tongkat Ali — 60 capsules. Eurycoma longifolia (Tongkat Ali) root-extract capsules — see the note on claims below.
How the stack fits together
Muscle is built on a surplus. A mass-gaining phase needs a consistent calorie and protein surplus plus progressive resistance training. A high-calorie gainer like Mutant Mass makes hitting that surplus easier than food alone when your appetite can't keep up.
Creatine is the most-studied training aid. Around 5 g of creatine monohydrate per day is the researched dose shown to support strength and power output during high-intensity training [1]. Check the Swoleys gummy label for its per-serve creatine content.
Train with intent. The EuphoriQ pre-workout is there for energy and focus before a hard session, so you can hold training quality through a bulk. It contains stimulants — assess your tolerance before a full serve.
Working the stack into a day
- Gainer: blend one serve of Mutant Mass with water or milk once or twice a day to top up calories and protein around training and between meals.
- Creatine: take the creatine gummies daily as directed on the label — timing doesn't matter, daily consistency does.
- Pre-workout: start with a smaller serve of EuphoriQ 20–30 minutes before training to assess tolerance; it contains stimulants.
- Tongkat Ali: take the NoWhey capsules as directed on their own label.
Built for a bulk — not a cut
- Hard gainers who struggle to eat enough to grow
- Lifters in a dedicated mass or off-season block
- Anyone who wants their gainer, creatine and pre-workout in one purchase
- Anyone under 18, pregnant or breastfeeding
- People sensitive to caffeine or stimulants (the pre-workout)
- Anyone wanting to lean out — this is a calorie-surplus stack, not a weight-loss product
- Anyone on medication or with a medical condition, without checking with their doctor first
Questions, answered
What's included in the Performance Mass Stack?
Four products in one box: Mutant Mass 5 lb (high-calorie gainer), Swoleys Creatine Monohydrate Gummies (12 serves), a MuscleTech EuphoriQ pre-workout (20 serves, Icy Snow Cone) and NoWhey Tongkat Ali capsules (60 caps). You get all four at a single stack price.
How much does the stack save me?
The stack is priced below the combined price of the four products bought individually. The exact saving and any current promotion are shown on this page and in your cart at checkout, so the numbers you see are always live rather than fixed in the description.
Is this a weight-loss product?
No. This is a calorie-surplus, mass-gaining stack built to help you eat more and train harder during a bulking phase. If your goal is to lean out or lose weight, this is the wrong stack — look at a lower-calorie protein and a structured deficit instead.
Why is Tongkat Ali in a mass stack?
It is included as a traditional botanical extract. We make no testosterone, hormone, libido or energy claims for it. The mass-support rationale for this stack rests on the gainer's calories and protein plus creatine, used alongside resistance training — not on this ingredient. Read the NoWhey label before use.
When should I take the pre-workout?
Take EuphoriQ about 20–30 minutes before training. It contains stimulants, so start with a smaller serve to assess your tolerance and avoid taking it late in the day if caffeine affects your sleep. Do not exceed the serving size on the label.
Do I still need to train and eat well?
Yes. These products support a mass phase; they do not replace it. Progressive resistance training and a genuine calorie surplus from whole food do the work — the gainer, creatine and pre-workout make that easier to sustain across a training block.
What's the difference between the Performance and Ultimate Mass Stack?
Both stacks share the same creatine, pre-workout and Tongkat Ali. The Performance Mass Stack includes Mutant Mass 5 lb; the Ultimate Mass Stack steps up to Mutant Mass 15 lb for a longer bulking block with more servings of gainer.
Are there allergens I should know about?
Yes. Mutant Mass contains milk. Always check each product's own label for its full ingredient and allergen information before use, and note that capsules may not be suitable for vegetarians or vegans. If you have a food allergy, read every label carefully.

Dietary supplements — not a medicine. This stack combines several dietary-supplement and sports-nutrition products. Always read each product's label and use as directed. Supplementary to a balanced diet and a structured training programme, not a substitute for either.
