If you're looking for the best supplements for muscle growth, start with this: supplements are the last 5%. Training, calories, protein, and sleep do the heavy lifting. The good news is the short list of useful supplements is small - and cheap.
Build the base first. Then use supplements to support it.
The Short List (What's Actually Worth It)
| Supplement | Best For | Notes |
|---|---|---|
| Creatine monohydrate | Strength + size | 3-5g/day. The most proven supplement for lifting. |
| Protein powder | Hitting protein | Not magic. Just convenient food. |
| Caffeine | Training output | Use strategically. Don't chase tolerance. |
| Vitamin D (if deficient) | Health baseline | Test if possible; don't mega-dose blindly. |
Supplements That Are Overrated for Muscle Gain
- BCAAs: unnecessary if you eat enough protein
- Test boosters: usually underwhelming and overpriced
- Mass gainers: often just calories you could eat as real food
- Glutamine: useful in some contexts, not a default muscle builder
How to Spend Your Money (In Order)
- Food first. Hit calories and protein consistently.
- Creatine. Cheap, safe, effective.
- Protein powder if needed. Convenience, not required.
- Pre-workout only if it helps you train harder. Otherwise, coffee works.
Simple Stack for 90% of Lifters
The Basic Stack
- Creatine monohydrate: 3-5g daily
- Whey or plant protein: as needed to hit your protein target
- Caffeine: 100-200mg before hard training (optional)
Frequently Asked Questions
Do supplements build muscle without training?
No. Supplements can support training and recovery. Muscle comes from progressive overload, enough calories, and enough protein.
What is the best supplement for muscle growth?
Creatine monohydrate, by a wide margin. After that, protein powder is helpful if it makes hitting protein easier.
Do I need protein powder?
No. It's just food in a convenient form. If you can hit protein with whole foods, you're set.
