Prohormone supplements are the strongest products we offer for strength increases and to build muscle. These should be considered only after exhausting natural progress, using natural muscle builders/supplements to increase testosterone and potentially looking into SARMs vs prohormones beforehand. Many people will want to jump straight into stacking prohormones without a full understanding of which will benefit them most, which is why we are attempting to address our post commonly asked questions about prohormones UK here!

What is a prohormone stack?

A prohormone stack is when a user combines more than one prohormone. You can select separate products and combine them, or alternatively some products are all-in-one stacks, such as Andro-1T and Andro-Deca.

Why stack prohormones?

There are several reasons why someone might stack prohormones.

Most commonly, someone will stack prohormones once they've experimented with one prohormone. If someone immediately starts using more than one prohormone, they won't know which is responsible for any benefits or side effects they see. By starting with one, you know what to expect and how you respond so it becomes easier to manipulate things from there based on what you see/experience.

Stacking also means you can use a lower dose of each prohormone and still make progress. This can be useful if one of the prohormones is methylated, meaning it is more stressful on the liver.

It also allows the user the experience the benefits of more than one prohormone. For example, they might use a test base to boost libido and wellbeing, and a 'dry' prohormone to reduce water retention and improve body composition.

What is the best prohormone stack? Here’s our top 4 list:

The best prohormone stack for you will be dependent on a number of factors such as how advanced you are, what supplements you have used in the past, and what your goal is. Common queries we get are from beginners, dieters or those looking to gain size or strength.

Best prohormone stack for beginners

First of all, it is important to note that it is absolutely NOT necessary for a beginner to use more than one prohormone at a time. We would advise starting with one compound, assessing your response over the duration of the cycle and over the PCT period (benefits, side effects, changes to health markers...) and repeating this for as long as you are able to progress. After several cycles, when results may start to become less pronounced, it might be appropriate to consider progressing to a prohormone stack.

For your first single prohormone, there are several milder options that might be suitable such as Halodrol, 11-OXO, or Delta 2 but for most people Androtest is probably the choice that makes the most sense as it's active. ingredient converts in your body into testosterone with as little as 3 capsules a day, with food, providing you supraphysiological levels of testosterone.

With this in mind, the first stack we would advise moving onto would be as follows:

  • Androtest
  • Epistane (Havoc)

Androtest

Androtest can be used as a standalone or in a stack for serious increases in muscle and strength. Androtest has only mild DHT conversion to keep potential sides manageable when stacked.

Havoc / Epistane

Havoc is classed as a highly anabolic supplement meaning it impacts predominantly on muscle tissue moreso than exhibiting androgenic effects such as sex drive or neural effects. As a pro-anabolic compound, Epistane promotes increases in strength and lean body mass with an anabolic/androgenic value (Q ratio) of 12.

Best prohormone stack for cutting & fat loss

It would be more useful to add a fat burner to your supplement routine if looking to burn as much body fat as possible, however some prohormones will give a better cosmetic look. Prohormones you should look for are 'dry' compounds which do not convert to estrogen. These will avoid water retention and bloating and, while they might not cause weight loss, will avoid any increases in water weight.

  • Androtest
  • Nano 1T

Androtest

The Cyclo 4-AD pro hormone within Androtest delivers a number of benefits including benefits to libido, strength and size and sexual performance. Androtest is non-methylated and acts as a test base to a number of different prohormones in a stack.

Nano 1t

Nano 1T is a nanoparticulated version of 1-testosterone, a non-toxic prohormone. 700% more anabolic than even testosterone. Nano 1t is perfect for dry gains in lean muscle mass.

As an alternative to this, you could also simply take Andro-1T which delivers the same active hormones as Nano 1T and Androtest but via a different delivery system and comparable doses.

Best prohormone stack for strength

This stack provides huge increases in strength and size in a short 4 week cycle. Being a more potent stack, this is best suited for advanced users. PCT of Alchemy should be used to avoid estrogen related sides and increase natural testosterone following the cycle.

  • M1, 4ADD
  • Nano 1T

M1, 4ADD

M1,4ADD is the prohormone to the anabolic Dianabol, loved by bodybuilders for the mass and strength gains it brings. M1,4ADD is ideal for someone happy to take a wet compound, that is to say, one that converts to some degree to estrogen. Despite estrogen's bad reputation among some bodybuilders, it plays a crucial role in both supporting increases in muscle mass and strength as well as supporting mood, joint integrity and libido.

Nano 1T

Being methylated this rules out any other methylated prohormone to stack with M1, 4ADD. Instead, Nano 1T would be a good option for lean gains. Androtest could be used instead for outright gains in mass, strength as well as libido but the risk of estrogen side effects would be higher so most would need to have an aromatase inhibitor to hand.

Best prohormone stack for bulking and mass

When muscle gains are the priority, you might want to look to more advanced prohormones which will allow you to gain as much size as possible in a short time. In the case of this cycle, we would run it for 4-6 weeks alongside health supplements. Post-cycle Alchemy and a testosterone booster such as Test Elite would be recommended as well as supplementing with natural anabolic ingredients such as laxogenin, phosphatidic acid, arachidonic acid and turkesterone. Every little will help you maintain your gains!

  • Androtest
  • Nanodrol

Androtest

As the best tool for delivering testosterone Androtest makes for a perfect stack with Nanodrol in our view for users looking for the mood and libido enhancing effects of testosterone as well as its muscle and strength building effects. A Nanodrol/Androtest stack is an explosive combination for users seeking rapid mass gains.

Nanodrol

Nanodrol users can expect to experience dramatic muscle growth and strength gains but given the potency of Nanodrol it is something which should remain the preserve of only advanced prohormone cycles.

Prohormone Stacks: our Conclusion

The most important thing before considering stacking a prohormone stack is to establish good training and dietary habits and ensure that you have been training consistently and intensely for a minimum of two years and are at least 21 years of age. Ideally, we would recommend not using prohormones until users have at least five years training experience and have experimented with the other natural bodybuilding supplements available on the marketplace today.

Once ready we would look at prohormones exhibiting high anabolic (muscle building) action with low androgenic and estrogenic action (low side effects). These compounds tend to be the easiest to recover from and the least stressful on the body enabling comfortable progress and retention of gains. The use of prohormones should always be done in conjunction with comprehensive on-cycle support to protect the liver, lipids and keep blood pressure within range among other markers. You should also always have the appropriate post-cycle therapy supplements at the ready. The best PCT for prohormones usually includes a test booster and AI if needed to restore healthy testosterone levels and control estrogen. Prohormone cycle guides can give further details on the best protocol.
