Our Breakdown of Greg Doucette's Supplement Protocol

We've run this stack ourselves and recommended it to countless customers. It's not about popping everything daily; it's targeted categories Greg discusses for bodybuilding gains. Start simple, scale as needed.

Foundation Supplements (Daily Staples We Swear By)

Stack Safety: Our Straight Talk

Healthy adults handle this fine, but we're direct: keep it simple.

20 Supplements at Once?
Possible, but dumb. Overload risks gut issues, stim crashes, waste. Stick to high-impact few.

Bad Combos?
Stim stacking kills—pre-workout + energy drink + burner = jitters, racing heart, wrecked sleep. Duplicate ingredients? Waste.

Turkesterone Safe?
Hyped in bro circles, but evidence lags basics like protein/creatine/caffeine. Optional at best; if meds or conditions, check a doc.

Our Rules
- Skip high-stim if BP or anxiety's an issue
- No sleep hacks via supps
- Scan labels for hidden overlaps
- Pregnant, nursing, under 18, medicated? Doc first

FAQ: Our No-BS Answers

Best Stack for Muscle Growth?
Protein powder, creatine, caffeine/pre-workout. Trains hard, feeds gains, stays consistent—done.

Top 3 Supplements?
1. Protein powder
2. Creatine monohydrate
3. Pre-workout or caffeine
Highest ROI for lifters.

Best for Getting Ripped?
Protein—preserves muscle, kills hunger on cuts. Caffeine aids intensity and control; deficit drives the shred.

20 Supplements at Once?
Sure, but pointless. Fewer, proven ones win—cuts cost, tracks results.

How Much Can Greg Bench?
Varies by era and gear, but his advice stems from real iron and coaching, not armchair talk.
