PEScience Smart Mass Clean Weight Gainer Sachets

PEScience Smart Mass in convenient single-serve sachets — a clean weight gainer for lean muscle in a grab-and-go format. Each box has 14 sachets you can toss in a bag and shake up anywhere, no scooping or measuring. Smart Mass is built on a whey + casein protein blend with slow-digesting carbs from Carb10® pea starch, Palatinose® and oat bran — maltodextrin-free, with no added fats — so you add quality calories to bulk without the junk-sugar crash.

Per sachet (one full serving): ~225 calories · 25 g protein · 25 g slow-digesting carbs · 5 g fat. One sachet is already a complete serving, so use one for a clean ~225-calorie, 25 g-protein shake, or two sachets on heavy days for ~450 calories, 50 g protein and 50 g carbs. Mix with water, or with milk for extra calories and creaminess.

About PEScience

PEScience (Physique Enhancing Science) is a US sports-nutrition brand best known for its flagship Select Protein and its whey-and-casein blend, with a reputation for dessert-like flavours and clean formulas. PEScience third-party tests both its raw materials and finished products (note: it is not Informed Choice / Informed Sport certified).

Why we carry it

Most mass gainers bury quality protein under cheap maltodextrin and a thousand-plus calories of sugar. Smart Mass is the rare clean gainer — slow-digesting carbs, no added fats, no maltodextrin — and the single-serve sachets make it genuinely portable. We brought the sachets in for lean bulkers who want clean calories without committing to a giant tub.

Key features

• 14 single-serve sachets — portable, no scoop needed (14 full servings per box)
• 25 g whey + casein protein per sachet (fast + slow digesting)
• 25 g slow-digesting carbs per sachet from Carb10® pea starch, Palatinose® and oat bran — low-glycemic, maltodextrin-free
• No added fats; no cheap simple sugars
• ~225 clean calories per sachet (one full serving); ~450 for a 2-sachet day
• Third-party tested raw materials and finished product (note: not Informed Choice / Informed Sport certified)

Who it's for

Hard-gainers, lean bulkers and busy athletes who want quality calories on the go — a clean post-workout or between-meals shake without the maltodextrin and sugar load of typical mass gainers. Keep it at 1 sachet for a solid 25 g-protein shake, or dial up to 2 sachets on heavy training days.

About this product

Each box contains 14 single-serve sachets, and each sachet is one full serving (~225 cal, 25 g protein, 25 g slow-digesting carbs, 5 g fat). Use two for a bigger ~450-calorie, 50 g-protein day. Mix with water, or with milk for extra calories and creaminess. Available in Gourmet Vanilla and Gourmet Chocolate.

Nutrition & ingredients

Per sachet (one full serving): ~225 cal, 25 g protein, 25 g carbohydrate (slow-digesting), 5 g fat. Protein from a whey concentrate + milk protein (casein) blend; carbohydrates from Carb10® pea starch, Palatinose® (isomaltulose) and oat bran. Maltodextrin-free, no added fats. Available in Gourmet Vanilla and Gourmet Chocolate. Contains milk. Always check the on-pack label for your flavour and full ingredients.

How to use it: sachets, macros & servings

The label basis. Unlike a scoopable tub, Smart Mass comes pre-portioned: the nutrition panel lists one full serving as a single sachet — about 225 calories, 25 g protein, 25 g slow-digesting carbs and 5 g fat. Each box holds 14 sachets = 14 full servings.

How to split it (our guidance). Because one sachet is already a complete 25 g-protein serving, a single sachet is a genuine standalone shake — you don't need to combine several the way you would with a loose-scoop gainer. On heavier training or bulking days when you want more, we suggest taking 2 sachets but spreading them out — e.g. one sachet post-workout and one between meals (or as a mini meal replacement) — rather than slamming both at once. Here's every level so you can dial in exactly what you want.

Sachets Calories Protein Carbs Fat Servings per 14-sachet box 1 sachet (one full serving) ~225 25 g 25 g slow 5 g 14 servings 2 sachets ~450 50 g 50 g slow 10 g 7 servings

Servings per box = 14 total sachets ÷ sachets used per shake.

Want the calories and protein but fewer carbs? Mix one sachet of Smart Mass with a scoop of a regular whey — for example PEScience Select Protein (~24 g protein per scoop) — so you keep Smart Mass's flavour and clean calories while bumping the protein and trimming the relative carb load. It's a simple way to make a box stretch and tune the shake to your macros.

An honest note: Smart Mass is a leaner "clean" gainer. At ~225 calories a sachet it is nowhere near the 1,000+ calorie mega-gainers — it's designed to add quality protein and slow-digesting carbs, not to flood you with cheap sugar. If you need a big calorie surplus, take 2 sachets and/or pair it with whole-food meals.

Smart Mass focuses on clean, slow-digesting carbs and quality protein instead of piling on cheap sugar and empty calories.

Pairs well with

• Whey & protein powders — stack extra protein on a hard-gainer day
• Creatine — pair with PEScience TruCreatine for size and strength
• Shakers — make the sachets a true grab-and-go

Great alternative to

If your usual mass gainer is sold out, or you want clean bulking calories without the maltodextrin and sugar of typical 1,000+ calorie gainers, Smart Mass targets the same goal — adding quality muscle-building calories — with a leaner, slow-carb profile you control one sachet at a time.

FAQ How many calories are in one Smart Mass sachet?

One sachet is a full serving: about 225 calories with 25 g protein, 25 g slow-digesting carbs and 5 g fat. Use two sachets on a heavy day for ~450 calories, 50 g protein and 50 g carbs.

How many sachets should I take, and how do I split them?

One sachet is already a complete 25 g-protein serving, so a single sachet is a legitimate standalone shake. When you want more on a training or bulking day, take two sachets but spread them out — for example one post-workout and one between meals — rather than both at once.

Is Smart Mass a "dirty" gainer?

No — it's a clean gainer. The carbs are slow-digesting (Carb10® pea starch, Palatinose® and oat bran), it's maltodextrin-free, and there are no added fats or cheap simple sugars.

What protein does it use?

A whey + casein blend, so you get fast- and slow-digesting protein in one shake.

Is it third-party tested?

Yes — PEScience third-party tests both raw materials and the finished product. Note it is not Informed Choice / Informed Sport certified.

How do I use the sachets?

Mix one sachet with water (or milk for extra calories and creaminess) in a shaker. Use one for a full ~225-calorie serving or two for a bigger day.

Version française

PEScience Smart Mass en sachets pratiques à portion unique — un gainer propre pour une prise de masse maigre, format prêt-à-emporter. Chaque boîte contient 14 sachets : aucune cuillère ni mesure. Smart Mass repose sur un mélange de protéines de lactosérum + caséine avec des glucides à digestion lente (amidon de pois Carb10®, Palatinose® et son d'avoine) — sans maltodextrine, sans gras ajouté.

Par sachet (une portion complète) : ~225 calories · 25 g protéines · 25 g glucides à digestion lente · 5 g lipides. Un sachet constitue déjà une portion complète : prenez-en un pour un shake propre de ~225 calories et 25 g de protéines, ou deux les jours intenses pour ~450 calories, 50 g de protéines et 50 g de glucides. Mélanger à l'eau, ou au lait pour plus de calories et d'onctuosité.

Comment l'utiliser : sachets, macros et portions

La base de l'étiquette. Contrairement à un pot à cuillère, Smart Mass est déjà portionné : le tableau nutritionnel définit une portion complète comme un seul sachet — environ 225 calories, 25 g de protéines, 25 g de glucides à digestion lente et 5 g de lipides. Chaque boîte contient 14 sachets = 14 portions complètes.

Comment la répartir (notre conseil). Comme un sachet est déjà une portion complète de 25 g de protéines, un seul sachet est un vrai shake autonome. Les jours plus intenses, nous suggérons de prendre 2 sachets, mais répartis — par exemple un après l'entraînement et un entre les repas — plutôt que les deux d'un coup.

Sachets Calories Protéines Glucides Lipides Portions par boîte de 14 1 sachet (portion complète) ~225 25 g 25 g lents 5 g 14 portions 2 sachets ~450 50 g 50 g lents 10 g 7 portions

Portions par boîte = 14 sachets au total ÷ sachets utilisés par shake.

Vous voulez les calories et les protéines, mais moins de glucides ? Mélangez un sachet de Smart Mass avec une mesure d'une whey régulière — par exemple la PEScience Select Protein (~24 g de protéines par mesure) — vous gardez la saveur et les calories propres de Smart Mass tout en augmentant les protéines et en réduisant la part de glucides. Une façon simple d'étirer la boîte et d'ajuster le shake à vos macros.

Une note honnête : Smart Mass est un gainer propre et plus léger. À ~225 calories le sachet, il est loin des méga-gainers de 1 000+ calories — il est conçu pour ajouter des protéines de qualité et des glucides lents, pas pour vous gaver de sucre bon marché. Pour un gros surplus calorique, prenez 2 sachets ou associez-le à des repas complets.

Pour qui

Pour les hardgainers et les athlètes occupés qui veulent des calories de qualité sur le pouce — sans la maltodextrine ni le sucre des gainers classiques. 2 sachets les jours d'entraînement intense, 1 sachet en collation ou en shake complet.
