Greg Doucette’s Complete Supplement Protocol

Greg doesn't push a one-size-fits-all daily ritual; it's a flexible framework we love because it adapts to your diet, size, training intensity, and goals. We use it to fill holes, amp sessions, and lock in macros. Here's the breakdown we swear by.

Foundation Supplements (Daily Staples We Never Skip)

#1) Protein Powder
Protein's non-negotiable in Greg's world, and we've hammered enough powders to know whey crushes it for hitting targets without calorie bloat. It's our go-to for post-workout or bridging meals.

Why We Rate It:

#2) Creatine Monohydrate
We've tested every form, and plain monohydrate is the king—Greg's right to prioritize it for raw strength and volume. It's backed by mountains of research we've pored over.

- Fills holes on limited eats
- Clutch for hard cuts

How We Dose It:
- 1 serving daily with meals

How We Run the Greg Doucette Stack (Timing & Schedule)

We keep it real—here's our daily flow.

| Time | What We Take | Why |
|---|---|---|
| Morning | Multivitamin, omega-3s, protein if short | Locks nutrition base |
| 20–45 min pre-workout | Pre-workout | Ignites energy, focus, output |
| Post-workout | Whey protein | Drives recovery, protein load |
| Between meals | Protein bar | Hits targets on the fly |
| Evening | Multi-source or collagen as needed | Tops off intake, eases adherence |

Core Rules:
- Creatine: 3–5 g anytime, every day
- Protein: Target-driven, not ritual
- Pre: Dodge late doses for sleep
- Bars: Tool, not crutch

No cycling needed for most—creatine, protein, multis/omegas run forever. For pre, we deload stims occasionally to stay sharp; if it fades, cut frequency.

Is This Stack Safe? Interactions & Warnings

Healthy adults handle protein/creatine/pre fine if dosed right—we've run it safely across our team. Watch stim overload if sensitive, late caffeine killing sleep, or GI bloat from some powders/bars. Don't let excess protein sideline real food. Kidney issues, BP, or stim woes? Check with a doc first.

Stacking 20 supps? Waste—stick to targeted: protein, creatine, pre as needed, micronutrients if diet sucks. Safest brand? Transparent labels, third-party tests, no shady blends, sane doses. And the safest gym supp? Creatine monohydrate, hands down— we've trusted it for years.
