On-Cycle Support Supplements: What You Need To Know

When you’re on cycle (taking SARMs, prohormones, or anabolic steroids to support your bodybuilding journey), your body can undergo significant physiological and hormonal changes. An on-cycle period can last for anything between 4 and 12 weeks, and you may need to provide your body with extra support during this time with on-cycle supplements.

On-cycle support is needed all year round if there are periods where you’re taking prohormones or oral steroids that contain methylated compounds. This is because the methyl group in these products can block important functions in the liver, causing various physical and emotional changes.

As a result, you may experience changes, such as:

 - Mood swings

 - Change in libido

 - Hair loss

 - Acne

 - Prostate issues

 - Joint pain

 - An increase in oxidative stress

 - An increase in LDL (low-density lipoprotein) cholesterol levels

 - A fall in HDL (high-density lipoprotein) cholesterol levels

Although you may already be using supplements such as protein powder on your bodybuilding journey, we recommend adding a specially formulated on-cycle supplement into your routine to help look after your organs and overall health during this stage of your training.

Complete Strength Health Aid Supplements

To help you support your health when you’re on cycle, Complete Strength Health Aid can help. These on-cycle support supplements are designed to support the normal functioning of your body’s vital organs, including your heart, liver, and kidneys.

This all-in-one formula has been designed with the athlete in mind, meaning you don’t have to take 8-10 different supplements or pills, and can instead have an all-in-one drink. Health Aid’s key ingredients are what make this product stand out in the market as one of the best all-in-one health and on-cycle supplements available today. These include:

 - NAC - for liver and kidney detoxification

 - Glutathione - helps to reduce fat in the liver

 - Citrus Bergamot - to support heart and cardiovascular health

 - ALA - lowers blood pressure and inflammation

 - Hydrocurcum - a type of rapidly absorbing curcumin, which helps to reduce free radicals and inflammation

 - Vitamin K2 - helps to reduce heart and blood vessel calcification

 - Vitamin D3 - helps with calcium absorption

 - CoQ10 - provides heart support

Let’s take a look at each of these on-cycle supplement ingredients in a little more detail:


NAC stands for N-Acetyl L Cysteine, a powerful antioxidant that can support your body to neutralise the increase in free radicals that’s part and parcel of being on cycle.

What’s more, NAC is needed to make glutathione, arguably the most important antioxidant in the body, as it plays a role in liver stage 2 detoxification. The liver is where these free radicals are packaged up to be disposed of from the body.


Being on cycle has been shown to decrease glutathione stores, so we’ve added L-Glutathione to our Health Aid supplements too, to give your liver that extra layer of support.

Milk thistle has also been added to the formula, which has been shown to reduce liver damage and acts by reducing free radical production.

Citrus Bergamot

Citrus Bergamot has been shown to reduce both LDL and HDL cholesterol. As a result, it may play a role in managing plaque deposition in the blood vessels that surround the heart.

Vitamin K2

Vitamin K2 is another key ingredient in our Complete Strength Health Aid formula. This vitamin is directly involved with regulating calcium deposition, subsequently supporting heart health.

This means the vitamin can help to reduce the plaque build-up in blood vessels and reduce blood clotting.

Vitamin D3

Vitamin D3 has also been added to the formula to regulate calcium absorption. When you’re on cycle and aren’t getting much exposure to natural sunlight, your body will be receiving lower levels of vitamin D3, so we’ve included this in our Health Aid supplements to help significantly reduce the risk of plaque build-up.


CoQ10 has been added to the formula to help support heart health. CoQ10 is involved in energy production and serves as a powerful antioxidant. What’s more, some chronic diseases, such as heart disease, have been linked to low levels of CoQ10.

The body’s highest concentrations of CoQ10 are found in the organs that require the highest energy demands, such as the heart. In an on-cycle supplement, it may help reduce oxidative damage and inflammation in the blood vessels surrounding the heart.


The powerful adaptogens Peak O2 and Hydrocurcum have also been included in our Complete Strength Health Aid formula. These two ingredients have powerful anti-inflammatory properties and are also strong antioxidants.

However, curcumin is typically poorly absorbed into the bloodstream, which is why we’ve added Bioperine, a natural substance that significantly increases the absorption of curcumin.


ALA stands for Alpha Lipoic Acid. Being on cycle can increase your blood pressure levels, but there is some evidence to suggest that ALA can help to lower this, supporting your heart and kidney health.

This ingredient has the added benefit of being a powerful antioxidant, and it may help to increase glutathione levels in the body.

Complete Strength Tudca Capsules

For further on-cycle support, you may also want to try taking our Complete Strength Tudca Capsules alongside our Health Aid formula. Tudca stands for tauroursodeoxycholic acid, and these capsules are designed to promote liver and kidney health, alongside supporting cellular health while you’re on cycle.

When To Stop Taking On-Cycle Supplements

It’s just as important to know when to stop taking on-cycle support supplements as it is to take them in the first place. Once you’ve stopped taking prohormones or steroids and your bodybuilding event has passed, it’s important to have a proper period of rest, of at least 10-12 weeks.

This rest period is essential to allow your body time to recover from the effects of the steroids, to protect your organs further. When you’re not on cycle, you don’t need to be taking on-cycle supplements, but you may want to consider other products to support your health and wellbeing.
