Every day you exercise at full intensity, take care of your diet, and strictly follow your training plan. However, despite this, you need to achieve the results that should be within your reach. What could be the reason for this In many cases, it turns out that the fault lies (literally!) in sleep or, instead, in recovery in the broadest sense. Nowadays, sleep problems have almost become a symbol of the times, as most people have trouble falling asleep at least once in a while or complain about poor sleep quality. Unfortunately, you need to be aware that, in the long run, such a situation can affect your efficiency at the gym.

So how can you remedy this First, it is worth implementing basic sleep hygiene principles. In addition to this, certain dietary supplements can be additional support. An exciting alternative has appeared in the offer of the company Kilo Labs. DROWNZz Night Time Sleep Formula is a product aimed at people who want to improve the quality of their sleep. On the one hand, this supplement is supposed to influence better and longer sleep, and on the other hand, support the regeneration of the body. Thanks to this, its action turns out to be effective.

Ingredients


InstAminos


the patented InstAminos formula was created through special laboratory processing of prevalent BCAA amino acids. Such processing has dramatically increased their effectiveness. As a result, InstAminos is a preparation that can support the body in muscle fibre regeneration.

Collagen peptides


daily stress can take a heavy toll on the state of the skin. Moreover, intense physical activity promotes the formation of various abrasions and injuries. That is why the composition of Kilo Labz DROWZz includes collagen peptides. With regular use, they can significantly improve the nutrition and condition of the skin. This is undoubtedly essential for those who want to enjoy the best-looking figure possible.

L-glutamine


glutamine is one substance that plays a vital role in our bodies. Among other things, this amino acid participates in regeneration and muscle expansion processes. In addition, glutamine regulates the metabolism of the intestines and also helps in the absorption of nutrients from food.

Phenibut


is a synthetic derivative of GABA or the well-known gamma-aminobutyric acid. The properties of phenibut are sure to be of interest to active people, as the described compound can both promote recovery and improve overall performance levels. In addition, it has nootropic properties that can positively affect concentration, for example.

L-arginine


arginine is best known as a compound that increases nitric oxide synthesis. However, it is also worth remembering its other properties. Arginine is also involved in the process of muscle tissue regeneration, and it also affects protein synthesis. These two aspects make it an essential compound for body regeneration.

L-ornithine


numerous everyday situations become a source of stress, raising cortisol levels in the body. Unfortunately, high cortisol levels are associated with many adverse effects. A classic example of such a condition is sleep problems. Fortunately, L-ornithine can help reduce cortisol levels. As a result, it will indirectly promote falling asleep and the quality of sleep itself.

5-HTP (5-hydroxytryptophan)


under the name 5-HTP, is a compound precursor of the well-known serotonin. Therefore, it has a very beneficial effect on the nervous system. Its action concerns the improvement of perceived mood and the beneficial effect on the length and quality of sleep. For this reason, 5-HTP becomes a perfect supplement for those who want to increase recovery efficiency.

Melatonin


is one of the most important compounds for our sleep. Melatonin, also known as the sleep hormone, is responsible for initiating processes in the body related to falling asleep. It probably doesn’t need to be explained why its deficiency can have serious consequences. To make matters worse, the blue light emitted, for example, by laptop and smartphone screens, inhibits melatonin secretion. Therefore, an extra dose of it in the form of supplementation can benefit falling asleep time and sleep quality.

Usage


The manufacturer recommends taking 1/2, 1 or 2 scoops of the product (depending on your needs and tolerance) about 20-30 minutes before bed.

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.

For example, if you order £100, you will earn 100 points (equivalent to £1), which you can redeem on your next order.

 

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.
