Protein supplements

Step 1

Protein — the foundation

Protein supports muscle repair and growth. Start with whey isolate or whey protein after training; use casein before bed, or grab a protein bar when you are out.

  • Whey isolate — cleaner macros for lean goals
  • Casein — slower release, good before bed
  • Protein bars — convenient between meals
Creatine supplements

Step 2

Creatine — proven and effective

One of the most researched supplements for strength and power. Creatine monohydrate is the gold standard — simple and effective. Stack it with protein and, if you struggle to eat enough, a mass gainer.

  • Supports strength and high-intensity performance
  • Well-studied with a strong safety profile
  • Affordable and easy to use daily
Pre-workout training

Step 3

Pre-workout — when you need an edge

Pre-workout formulas can boost energy and focus before training. Start with a half serving to assess tolerance. Prefer convenience? Try an energy shot, and keep electrolytes on hand for longer sessions.

  • Caffeine-based options for energy and alertness
  • Stim-free alternatives available
  • Not essential — add when basics are covered
