The best supplements for muscle growth,
beyond creatine.
The best supplements for muscle growth make a short, honest list. One of them has strong evidence and everything else is supporting cast. That one is creatine monohydrate.
The rest earn their places situationally: breakdown protection when you're new or older, minerals your diet may run short on, and herbs with emerging testosterone data we grade exactly as the research does. Training and protein still do most of the work.
| Supplement | Evidence | Daily dose | When |
|---|---|---|---|
| Creatine Monohydrate | strong | 3-5 g | Morning, Midday, Post-workout |
| HMB | moderate | 1.5-3 g | Morning, Post-workout |
| Magnesium Glycinate | moderate | 100-350 mg elemental | Night |
| Ashwagandha | emerging | 300-600 mg | Morning, Night |
| Tongkat Ali | emerging | 200-400 mg | Morning |
| Fenugreek Extract | emerging | 500-600 mg | Morning |
| Boron | emerging | 3-6 mg | Morning |
The stack, ranked
3-5 g · Morning, Midday, Post-workout
Creatine monohydrate is the most tested supplement in sports nutrition: strong evidence for strength, power, and lean mass while training, with an extensive safety record in healthy adults. 3 to 5 g daily. Timing barely matters; consistency is everything.
1.5-3 g · Morning, Post-workout
HMB shines where muscle is at risk: moderate evidence for reducing breakdown in untrained and older lifters, with less clear benefit once you're well-trained. 1.5 to 3 g daily, split across the day. It stacks cleanly with creatine.
100-350 mg elemental · Night
Magnesium's muscle case is nutritional: moderate evidence tied to adequacy and neuromuscular function. If your diet runs low, 100 to 350 mg elemental in the evening covers the gap and helps you wind down. Stay at or under the 350 mg ceiling.
300-600 mg · Morning, Night
Ashwagandha's strength data is emerging, and its plausible path runs through stress and sleep rather than direct anabolism. Moderate evidence supports lower cortisol. 300 to 600 mg with food, cycled 8 weeks on and 2 off.
200-400 mg · Morning
Tongkat ali carries emerging evidence for modest testosterone and cortisol modulation, with the emphasis on modest. Use a standardized extract, 200 to 400 mg in the morning with food, cycled. Skip it entirely with hormone-sensitive conditions.
500-600 mg · Morning
Fenugreek's testosterone and libido data is emerging; its stronger suit is actually glycemic control, at a moderate grade. 500 to 600 mg with a meal. The maple-syrup smell it gives some people is documented and harmless.
3-6 mg · Morning
Boron is the cheapest experiment here: moderate evidence for bone density, emerging for hormonal modulation. 3 to 6 mg with food is plenty. The adult ceiling is 20 mg per day, and more does nothing extra.
How to combine them
Creatine is daily, forever, including rest days. If you want faster saturation, the optional loading phase is 5 g four times a day for 5 to 7 days, then back to 3 to 5 g.
HMB splits into 1 g doses across the day or rides along with meals. Magnesium takes the evening slot. The herbs, tongkat ali and fenugreek, take mornings with food and get cycled, roughly 8 weeks on and 2 off.
One caution in plain words: tongkat ali and fenugreek are hard stops during pregnancy. And if you take thyroid, diabetes, or blood pressure medication, run the herb half of this stack past your doctor first.
Common questions
Do you need to load creatine?
No. Loading saturates your muscles faster, but a steady 3 to 5 g daily reaches the same endpoint. Pick whichever you'll actually stick to. Consistency beats protocol.
Which muscle supplements actually affect testosterone?
Graded honestly: tongkat ali and fenugreek show emerging evidence for modest testosterone modulation. Nothing here replaces training, sleep, or eating enough. Maca, often marketed for hormones, does not directly raise hormone levels at all.
Is HMB worth it if you already train?
Probably not much. The benefit concentrates in untrained people and older adults at risk of muscle loss. If you're well-trained, creatine remains the better spend.
