Post-cycle therapy is a recovery protocol used after completing a SARMs cycle to restore your body’s natural testosterone production. During the cycle, the SARMs partially inhibit your hypothalamic-pituitary-gonadal axis - the hormonal feedback loop that regulates testosterone production. After the cycle, your body needs time to restart its own testosterone production. PCT stimulates this process and helps preserve the muscle gained during the cycle.
Selective androgen receptor modulators (SARMs) are synthetic medications that mimic testosterone's muscle-building effects. When athletes and bodybuilders use SARMs to build muscle mass and boost strength, they can likely suppress natural testosterone levels. It can be bad for your health, leading to symptoms such as low libido, muscle loss, testicular atrophy, and mood swings. PCT for SARMs helps restore the natural testosterone production after completing the cycle. This blog illustrates SARMs post-cycle therapy, signs and symptoms of testosterone suppression, and why hormonal balance matters.
SARMs are selective androgen receptor modulators that selectively bind to androgen receptors in bone and muscle tissue. They imitate the anabolic effects of testosterone, similar to anabolic steroids. In fitness communities, they are used for rapid muscle growth, fat reduction, and increased strength and endurance. Research has shown SARMs for treating conditions like osteoporosis, cancer cachexia (muscle wasting), and weakness. But users may also experience testosterone suppression, gynecomastia (enlarged breast tissue), and testicular shrinkage with long-term use. It is recommended to seek medical guidance before starting your cycle.
Almost all SARMs can suppress natural testosterone production to some extent. They bind to androgen receptors and stimulate negative feedback on the body's natural hormone production. The degree of suppression depends on the medicine, dosage, and cycle length.
Here are some common SARMs that suppress testosterone:
Testolone (RAD-140)
Andarine (S-4)
Ostarine (MK-2866)
Ligandrol (LGD-4033)
Post-cycle therapy helps restore natural testosterone production after a SARM cycle. Without PCT, your hormonal balance can remain disrupted for weeks or even months after a cycle.
The following are some signs of low testosterone:
Without sufficient testosterone, your body’s mode shifts from anabolic (building) to catabolic (breaking down).
Low Testosterone is a factor in fat storage, especially around the midsection.
Fatigue, low energy, irritability, and reduced motivation are the typical symptoms of suppressed testosterone.
Reduced libido and sex drive.
Low hormonal support leads to drops in training performance.
PCT isn’t just about feeling better; it’s about preserving the lean muscle gained during the cycle.
You can find the following PCT compounds at our online UK steroids shop:
Nolvadex is an important SERM (selective estrogen receptor modulator). It blocks estrogen at the pituitary, promoting the release of LH (luteinising hormone) and FSH (follicle-stimulating hormone). It is the most popular PCT protocol for SARMs cycles.
Typical dosage: 20mg/day for 1–2 weeks, then 10mg/day for 3–4 weeks.
Best for: Mild to moderate testosterone suppression after most SARM cycles.
Clomiphene Citrate (Clomid) is another SERM that functions similarly to Nolvadex but is generally considered stronger. It is usually used for heavier suppression.
Typical dosage: 50mg/day for 1–2 weeks, then 25mg/day for 3–4 weeks.
Best for: Significant suppression (stacked cycles, potent compounds like YK-11 + RAD-140)
People may suggest different PCT supplements to help restore hormonal balance. A few key tips and behaviours during post-cycle therapy can deliver a large impact.
The following habits can be considered part of the treatment, if only because they generally have a positive effect on your body.
Taking proper nutrition and rest can make a big difference during your PCT protocol. Both proper rest and correct nutrition are crucial to keep your long-term gains, which is what you took your cycle for.
To preserve your long-term gains, exercise can be very helpful. It is an essential part of staying healthy, and you should train your muscles with the activities they need. It can create a nice balance between rest and engaging your body in physical work. However, you need not exhaust your body where it can’t recover properly.
You should not start cycling SARMs again until your PCT is finished. You’re trying to recover the hormones in your body due to side effects like testosterone suppression from SARMs. By initiating another SARMs cycle, you’re making it harder for the body to reset hormone processing properly. Let your PCT complete and take a bit of a longer gap before you start another SARMs cycle.
Yes, most SARMs can lower your natural testosterone levels. An effective post-cycle therapy helps your body restart its own hormone production after a cycle.
Signs like low energy, mood swings, or a drop in strength after your cycle indicate the need for PCT. Blood work is the best way to confirm if your hormone levels need help bouncing back.
Yes. It is very important if you want to keep your muscle gains and stay healthy. Skipping it can lead to long-term hormone imbalances or losing the progress you worked hard for.
Common side effects include mild headaches, nausea, acne, blurred vision, anxiety, and temporary breast tenderness.

Post-cycle therapy becomes crucial after taking a steroid or SARM cycle because these compounds interfere with your body’s hormones. PCT can stop suppression by correcting the way your body produces hormones. In this way, you can also protect your long-term gains from SARMs and avoid risks or side effects. If you ignore taking PCT, you are creating a chance to harm your body, or you can experience long-term suppression. It is recommended to go for the therapy after completing the SARMs cycle to get the best possible outcomes.
