Description
BioTechUSA L-Arginine – Pure Amino Acid Mega Caps & Powder
BioTechUSA L-Arginine is a pure L-arginine supplement available as 90 mega caps or a 300g powder. L-arginine is a conditionally essential amino acid found in foods such as meat, fish, nuts and seeds, and it is the amino acid the body uses to produce nitric oxide. Made by long-standing European brand BioTechUSA, it is a staple for bodybuilders who like to keep their supplement stack simple and flexible.
Key Benefits
- Pure L-arginine – a single-ingredient amino acid with no stimulants.
- Mega caps – larger capsules mean fewer to swallow per serving.
- Flexible powder – 300g tub lets you adjust your serving and mix it into other drinks.
- Nitric oxide precursor – arginine is the amino acid the body converts into nitric oxide.
- Stack-ready – works alongside citrulline, creatine or your usual pre-workout.
Who Is It For?
Ideal for bodybuilders, physique athletes and gym-goers focused on pump-style training. The capsules suit people who want convenience, while the powder suits home stack-builders who prefer to measure their own serving.
Flavours & Sizes
Choose between 90 mega caps or a 300g powder.
FAQs
Should I choose capsules or powder?
Capsules are quick and tasteless, while powder is better value per serving for many users and easy to mix. Both provide L-arginine; check the label on your pack for serving details.
Does the powder taste strong?
Plain L-arginine has a naturally bitter taste, so many people mix it into juice or a flavoured drink.
