Ingredients


Ajinomoto L-glutamine


an amino acid crucial for many metabolic processes. It supports nitrogen metabolism, allowing the removal of unnecessary ammonia, which is produced during protein metabolism. In addition to cleansing the body of unfavourable metabolic products, it strengthens strength, endurance, and the nervous system.

Micronised L-leucine


a branched-chain amino acid that acts on the hypothalamus, where the satiety centre is located. It helps reduce appetite and thus supports building a slim figure and lean muscle mass. It has a noticeable effect on serotonin levels responsible for sleep quality and rest. Leucine is used in athletes to postpone fatigue to train for longer successfully.

Micronised L-isoleucine


a natural essential amino acid present in most proteins. Significant amounts are also present in casein, blood plasma proteins or haemoglobin. It plays a crucial role in tissue and muscle regeneration. In addition, it has a perfect effect on the condition of hair and nails, regulates blood glucose and protects muscle tissues from breakdown.

They are micronised L-valine


an essential amino acid for muscle protein synthesis and energy production. It is a critical amino acid that helps build muscle, facilitates muscle function, and activates somatotropin. It balances muscle mass and fat stores in the human body.

Micronised L-taurine


an amino acid that influences the body’s osmoregulation and the process of protein synthesis. It helps improve performance during exercise and is an anabolic that accelerates the flow of nerve signals from the muscles. In addition, it accelerates their regeneration.

Micronised L-citrulline


a non-protein amino acid often used in medicine and sport. Responsible for participation in the urea Krebs cycle. Thanks to its action, ammonia is converted into urea, thus reducing the risk of sourdough, which can occur after active training. In addition, it dilates blood vessels and increases nitric oxide production.

Micronised L-tyrosine


an organic compound that regulates cell metabolism. Has a crucial function as a precursor in synthesising neurotransmitters, i.e. norepinexxrine, dopamine and adrenaline, in the human body. It reduces physical and mental fatigue during prolonged and intensive training. In addition, it increases concentration. It is desirable when taking a reduction or with general fatigue. It supports brain function and increases stress resistance.

an organic chemical compound, an amino acid involved in many processes in the human body. Its action affects the proper functioning of the digestive, muscular, sexual, circulatory and immune systems. It helps build muscle mass and reduces body fat. It removes ammonia and promotes growth hormone j is a nitrogen precursor.

Micronised L-lysine


an amino acid that is the basis for building proteins found in muscles, bones and tendons. Significantly accelerates the growth of muscle mass and the regeneration of damaged tissues. It influences protein absorption and supports skin, bones, tendons and cartilage tissue conditions. Reduces fatigue, boosts energy and improves concentration.

Micronised L-phenylalanine


is an organic chemical compound that belongs to the exogenous amino acids. Its use has measurable benefits for the human condition and well-being. It positively affects the nervous and endocrine systems, increasing performance and mental concentration. It enhances cognitive processes.

Micronised L-threonine


one of the essential protein amino acids. It supports the function of many systems and is vital for human skin and enamel. It is also actively involved in the growth of muscle mass.

They are micronised L-methionine


an essential protein amino acid part of the protein structure. It must be supplied to the body during a meal. Methionine has a crucial effect on improving the condition of nails, skin and hair. It influences body regeneration and tissue growth. It exhibits detoxifying properties.

We dispatch EU orders weekly. Orders placed by Friday morning are included in that week’s consolidated shipment from the UK to our EU hub.

The transfer to the EU hub usually takes around 5–7 days. We handle customs and import processing as part of this consolidated shipment, so customers don’t need to complete customs clearance themselves or pay additional import fees on delivery.

Once your parcel reaches the EU hub, DPD takes over. Tracking becomes active after the first DPD scan, and delivery usually takes a further 3–5 working days.

Please note that there is no tracking during the UK-to-EU hub transfer. All EU orders are covered by our 100% delivery guarantee.

First, you’ll need to register for an account with our store to earn your points. Our points system lets you earn points on every purchase. For every £1 spent on our website, you earn 1 point. For every 100 points, you get £1 in store credit.

Yes! You can pay for your supplements using Bitcoin (BTC), Ethereum (ETH), USDT, and many other cryptocurrencies via our secure payment partner, NOWPayments.

 

To ensure reliable delivery and avoid customs issues, we ship all EU orders via our consolidated weekly route from the UK to our EU hub.

How it works:

  • EU shipments leave the UK once per week, usually on Friday.
  • Orders placed before the weekly cut-off are included in that Friday’s shipment.
  • Orders placed after the shipment has already left will wait for the next weekly dispatch.
  • The consolidated shipment usually reaches our EU hub around the following Thursday.
  • We then hand parcels to DPD, usually the same day.
  • DPD delivery normally takes around 3–4 working days after the parcel is scanned at the EU hub.
  • Tracking becomes active only after DPD receives and scans the parcel.
  • Customs and import processing are handled within the consolidated route.
  • Customers do not need to arrange customs clearance or pay additional import charges on delivery.
  • Our 100% delivery guarantee covers all EU orders.

Example:

If you place your order on Thursday before the cut-off, it should normally leave the UK on Friday, reach our EU hub the following Thursday, and then arrive with you around 3–4 working days later.

If you place your order after that Friday shipment has already left, your parcel will wait for the next weekly dispatch, so the total delivery time will be longer.

Select Pay by Link at checkout and place your order. Our team will then email you a secure payment link, which you can use to pay by credit or debit card.

We send payment links Monday–Friday, 8:00–16:00 UK time. We process orders placed outside these hours on the next working day. Please complete payment within 24 hours; otherwise, we may cancel the order.
