Ingredients
What we cover, the effective dose ranges from human studies, and how strong the evidence is.
8 ingredients found
Beta-Alanine
3.2–6.4 g effective dose
4/5
Beta-alanine is a non-essential amino acid that combines with histidine to form carnosine in muscle tissue. Carnosine buffers acidity during high-intensity work.
Caffeine
100–400 mg effective dose
5/5
Caffeine is a central nervous system stimulant and the most studied ergogenic aid in sport science. It blocks adenosine receptors, reducing perceived exertion and improving alertness.
Copper Peptides (GHK-Cu)
0.05–3 % effective dose
3/5
GHK-Cu is a tripeptide bound to a copper ion. It is involved in wound healing and signals fibroblasts to upregulate collagen and elastin production.
Creatine Monohydrate
3–5 g effective dose
5/5
Creatine monohydrate is the most extensively researched form of creatine. It increases phosphocreatine stores in skeletal muscle, improving rapid ATP regeneration.
Hyaluronic Acid
0.1–2 % effective dose
3/5
A glycosaminoglycan that holds many times its weight in water. Topical hyaluronic acid is a humectant that draws moisture into the upper layers of the stratum corneum.
L-Citrulline
6–8 g effective dose
3/5
An amino acid that the body converts to L-arginine, raising plasma arginine more reliably than supplemental arginine itself. This supports nitric oxide synthesis and vasodilation.
Niacinamide
2–10 % effective dose
4/5
Niacinamide (vitamin B3) supports the skin barrier and modulates sebum production. It is one of the most well tolerated actives in skincare.
Retinol
0.025–1 % effective dose
5/5
Retinol is a vitamin A derivative that converts to retinoic acid in the skin. Retinoic acid binds nuclear receptors that regulate keratinocyte differentiation and collagen synthesis.
