What are prohormones?

The question of prohormones seems to intrigue many due to their similarity with anabolic steroids. Just like illegal anabolic steroids, they serve as a testosterone precursor. In other words, they are raw materials that our body utilizes to make hormones. However, there is one main difference between prohormones and anabolic steroids. Namely, prohormones lack one molecule which the body only creates after the formula is exposed to enzymes within the body.

What is SARMS?

SARMs or Selective Androgen Receptor Modulators are a group of medicinal compounds that have comparable properties to anabolic agents, but with decreased androgenic properties. This property grants SARMS the benefit of tissue selectivity, the lack of steroid-related side effects, and androgen-receptor specificity.

What is Post Cycle Therapy (PCT)?

When you use prohormones, your natural hormone levels will alter. This means, amongst others, that your testosterone levels will be higher. Consequently, you will be all fired up and working out like crazy. After one month of taking such an effective product, your body needs time to readjust. Therefore, the natural testosterone-making mechanism of your body will often be suppressed and may need a little time to readjust to normal levels. To assist your body in this process, we recommend using a Post Cycle Therapy product like T Matrix.

Is it safe to use your products?

Our first and main concern is your health and body. Therefore, we only offer products of the highest quality and we take care of production ourselves. Although the products we offer are safe, misuse of them could harm your body. For this reason, we, first of all, recommend you take into account the prescribed dosage and use. Second, we recommend checking with your physician or your trainer to check if certain supplements are the right fit for your body and training program.

Ordering & Shipping

What payment options do you offer?

We currently work together with Payzone to ensure safe payment. Payzone currently accepts Visa, Visa Electron, MasterCard, Maestro, and American Express.
Although we prefer you to make use of our online payment gateway set up by Payzone, you could also make a bank transfer to complete your payment. Please reach out via WhatsApp for more information.

I got an error during the payment process, what caused this?

The most common reason your bank will decline the payment is that the billing details you provided during check-out are not fully equal to the details registered for the card you are using. Please always double-check that the address linked to your credit card and your billing address is identical. If you need to add a flat or unit number it might be better to provide this via the separate input for the shipping address instead of via the billing details. If you would still run into trouble after all, please reach out to us ( or +31 494 28 40 81) and we will gladly find a solution together.

Where do you ship?

Although we only products within the UK, our products are distributed worldwide. Unfortunately, there are a few exceptions to this. At this point, we are unfortunately not in the possibility to provide our products to customers within Norway, Sweden, Finland, and Canada.

How are my shipping costs calculated?

Shipping costs depend upon two factors. First, shipping costs depend on the location where you want your products delivered (shipping address). Second, the combined weight of the products you ordered is taken into account: the more products (or weight) you order, the higher shipping costs will be.

How long does it take to receive my order?

Orders within the UK should arrive within 2-3 working days. Orders outside the UK should arrive within 5-10 working days, depending on your exact location. Please note that the aforementioned time frames are indicative. Due to the combination of Brexit and COVID-19 package delivery could experience shifts in delivery time.
Once we shipped your order, you will receive an email with your tracking number which you can use to track your order via the website of Royal Mail.

Do you offer express shipping?

We have decided to not offer the option of express shipping. The reason for this is that we think that by giving delivery services just a little more time for your delivery to take place, they can schedule deliveries more efficiently and by this means operate sustainably. It is not much, but in this way, we try to do our part for the climate.
