Protein powder — reach your daily target first
Protein is the non-negotiable. Aim for roughly 1.6–2.2 g per kg of bodyweight per day from food plus powder. A whey blend is the most cost-effective way to top up; a whey isolate is lower in lactose and fast-digesting for around training. Plant options cover dairy-free lifters.
PEScience Select Protein (27 servings)
From $75.99 CAD · 27 servings · whey concentrate + isolate
Our #1-selling protein for a reason: PEScience Select blends whey concentrate and isolate with a flavour system that mixes clean. A versatile everyday protein to anchor your daily target.
PVL IsoGold Whey Isolate & Hydrolysate (1.85lb)
From $72.99 CAD · ~30 servings · fast-digesting iso/hydro
Whey isolate plus hydrolysate — lower in lactose, fast to digest, and high in protein per scoop. A strong pick around training or for lifters with sensitive stomachs.
Optimum Nutrition Gold Standard 100% Whey Protein Powder (1.5 lb)
From $64.99 CAD · 1.5 lb · isolate-forward blend
Gold Standard is one of the most recognised whey blends in the world. The 1.5 lb tub is an easy entry point; the 5 lb tub is the value size for daily users.
Allmax Nutrition Isoflex Whey Protein Isolate (1lb)
From $44.99 CAD · 1 lb · whey isolate
A cleaner isolate from a Canadian brand — useful when you want protein with minimal carbs and fat. A good deficit-friendly option too if you are lean-bulking.
PEScience Select Vegan Protein (27 servings)
From $54.99 CAD · 27 servings · pea + brown rice
A dairy-free option that still mixes and tastes well. Pairs pea and brown-rice protein to round out the amino profile for plant-based lifters — one of our steadier slow-and-worthy sellers.
Creatine monohydrate — small cost, strong evidence
Creatine monohydrate at 3–5 g per day is the most-researched sports supplement and may help support strength, power and lean muscle mass when combined with resistance training. Monohydrate is the form with the most data. A short optional loading phase (about 20 g/day split over 5–7 days) speeds saturation but is not required.
PVL 100% Pure Creatine Monohydrate — Micronized, Pharmaceutical-Grade, Unflavoured (300g / 60 Servings)
From $22.99 CAD · 60 servings · micronized monohydrate
Pharmaceutical-grade micronized monohydrate, Informed Choice certified, at about $0.38 a serving. This is where we tell most people to start — and the 1000 g tub drops the cost per serving even further.
Bowmar Nutrition Creatine13 — Absorption Creatine Blend (30 Servings)
From $54.99 CAD · 30 servings · absorption blend
For shoppers who specifically want a multi-form creatine matrix rather than plain monohydrate. A premium, lower-volume option we keep for the enthusiasts who ask for it.

Mass gainers — only if you can't eat enough
A mass gainer is a high-calorie protein-and-carb powder for hardgainers who struggle to eat enough to grow. If you already hit your calories, whole food plus a standard protein is cheaper. Check calories and sugar per serving on the label.
MUTANT Mass Gainer Protein Powder | High-Calorie Weight Gainer (15 lbs)
From $129.99 CAD · 15 lb · weight-gain formula
A large-format high-calorie gainer for serious hardgainers — protein plus carbs to make surplus calories easier to drink. Buy the sachets first if you want to trial the taste.
PEScience Smart Mass Clean Weight Gainer Sachets
From $3.99 CAD · 14 single-serving sachets
The low-risk way to try a cleaner gainer before committing to a tub — single-serving sachets you can throw in a gym bag.
EAAs, casein & pre-workout — the optional edges
None of these are required, but each earns a place for the right lifter: EAAs/BCAAs for intra-workout sipping, casein for slow overnight protein, and pre-workout for training energy and focus.
Mutant Hardcore BCAA (30 servings)
From $39.99 CAD · 30 servings · 9.7 g aminos per scoop
A well-dosed amino scoop for sipping through training. Most useful if your daily protein is already high and you want an intra-workout drink.
ALLMAX CaseinFX — Slow-Release Micellar Casein Protein Powder (2lbs)
From $59.99 CAD · 2 lb · micellar casein
Micellar casein digests slowly, making it a convenient overnight or between-meals protein. Stock runs lean on this one, so grab it while it’s on the shelf.
Mammoth Pump Pre-Workout (60 servings)
From $59.99 CAD · 60 servings · pump-focused
Sixty servings of a pump-focused pre-workout — one of the best cost-per-serving pres we stock. Great for training energy without a premium price.
PEScience Amino IV BCAAs/EAAs + Electrolytes (30 servings)
From $49.99 CAD · 30 servings · EAAs + electrolytes
EAAs paired with electrolytes for hydration during longer sessions — a quieter seller we keep for lifters who train long and sweat hard.
Which muscle-gain supplement is right for you?
- You just want the essentials: a protein powder (PEScience Select or Optimum Gold Standard) plus creatine monohydrate (PVL). That covers 90% of the benefit.
- You have a sensitive stomach or train fasted: a whey isolate/hydrolysate — PVL IsoGold or ALLMAX Isoflex.
- You can't gain weight no matter what: add a mass gainer (Mutant Mass) on top of meals.
- You are dairy-free: PEScience Vegan or PVL Plant-Pro.
- You want an overnight protein: ALLMAX CaseinFX before bed.
- You want training energy: Mammoth Pump (best value) or PEScience Prolific.
Muscle-gain supplement FAQ
What supplements actually help you build muscle?
The two most-evidenced are protein powder (to reach a daily protein target, roughly 1.6–2.2 g per kg of bodyweight) and creatine monohydrate at 3–5 g per day, which may support strength and lean-mass gains alongside resistance training. Everything else — mass gainers, EAAs, casein, pre-workout — is a convenience or a small edge on top of training, protein and calories. Always read and follow the label.
Do I need creatine to gain muscle?
You do not need it, but creatine monohydrate is the most-researched sports supplement and is inexpensive, which is why we list it first. Around 3–5 g per day may help support strength, power and lean muscle mass when combined with resistance training. Monohydrate is the form with the most evidence.
Whey isolate or whey blend for building muscle?
For total daily protein, a whey blend (like PEScience Select or Optimum Gold Standard) is cost-effective and works well. A whey isolate or isolate/hydrolysate (like PVL IsoGold or ALLMAX Isoflex) is lower in lactose and digests fast — a good choice around training or for sensitive stomachs. Both help you hit your protein target.
What is a mass gainer and who is it for?
A mass gainer is a high-calorie protein-and-carb powder for people who struggle to eat enough to gain weight — often called hardgainers. If you already eat enough, whole food plus a standard protein powder is usually the better and cheaper route. Read the label for calories and sugar per serving.
Should I take casein before bed?
Casein is a slow-digesting milk protein that releases amino acids over several hours, so some people use it as an overnight or between-meals protein. It is optional — hitting your total daily protein matters most — but it is a convenient way to add protein at night.
Do you ship muscle-building supplements across Canada?
Yes. We ship same-day from our Montreal warehouse on orders placed before 4 PM EST, with free shipping on qualifying orders and free 30-day returns. All pricing is in CAD — no duties or USD conversion.
