Every sports performance entry in the Typed supplements library. Each one is a full page: what it does, stage by stage, and what the evidence says.
- AgmatineA by-product of arginine, studied for blood flow and nerve signalling.
- BCAAsThree specific amino acids, sold on partial evidence.
- Beef Protein IsolateA protein powder made from beef, offering a dairy-free alternative to whey with fairly similar muscle-building results in the research that exists.
- Beta-AlanineThe one that gives you the tingly skin feeling.
- Betaine Anhydrous (TMG)Not the same thing as beet juice, despite the name overlap.
- Casein ProteinA slow-digesting milk protein that clots in your stomach, releasing amino acids gradually over hours rather than all at once.
- Citrulline MalateYour body turns it into the amino acid that widens blood vessels.
- Creatine MonohydrateOne of the most heavily studied supplements there is.
- ElectrolytesNot always needed — it depends how much you actually sweat.
- Essential Amino Acids (EAAs)The nine amino acids your body can’t produce on its own, taken as a fast-absorbing powder to help trigger muscle repair and growth.
- Hemp ProteinA plant protein from hemp seeds that your body digests surprisingly well, though it hasn’t been tested in the same kind of muscle-building trials as whey or rice protein.
- HMBA by-product of an amino acid, studied for slowing muscle breakdown.
- L-ArginineThe original "pump" amino acid — though most of it never survives your gut.
- L-CarnitineShuttles fat into the part of your cells that burns it.
- L-GlutamineYour body already makes plenty of this — extra rarely helps healthy gym-goers.
- Pea ProteinA plant-based protein made from yellow split peas, shown in recent studies to build muscle about as effectively as milk protein.
- Rice ProteinA dairy-free, plant-based protein powder from rice that performed about as well as whey for building muscle in an 8-week study — though the powder itself is naturally a bit short on one amino acid.
- Sodium BicarbonateBaking soda you drink before a hard, short workout to fight off that burning muscle feeling.
- TaurineOne of the most abundant amino acids in your body, and you make it yourself.
- Whey ProteinThe 30-minute window after training is mostly a myth.
- ZMAZinc, magnesium, and B6 in one product — helpful if you’re low on them, not a testosterone shortcut.
