Understand what a product is for before deciding whether to buy it.
Creatine: questions to answer
Read the label, ingredient amount and intended use. Check whether evidence addresses the actual ingredient and population, rather than only the brand’s marketing. Discuss suitability with a clinician when you have health conditions or take medication. This checklist does not prescribe a dose.
Protein powders and bars
Compare the protein per serving, price per serving, ingredients, allergens and tolerability. A powder is a food convenience; buying one is not a requirement for using this site’s guides.
Whey and plant options
Read the source and allergy information. Compare products using the amount you will actually consume rather than package size. Choose according to dietary needs and tolerance.
Stimulant and combination products
Check the total stimulant amount across coffee, drinks and supplements. Avoid guessing from a proprietary blend. Review interactions and your sleep schedule before use.
Amino-acid products
Ask what specific gap the product addresses in your current diet. Do not assume more separate ingredients improve your results.
Hormone-related claims
Do not use a retail supplement to self-diagnose or treat a hormonal problem. Symptoms and treatment decisions belong with a qualified clinician.
Before any purchase
Check ingredient transparency, manufacturer details, batch testing, expiration, drug interactions, health conditions and the seller’s return terms. Certification is not a guarantee of benefit. Avoid claims of guaranteed rapid muscle growth.
