PCT & Cycle Support
About this range
PCT and cycle support products for the UK: the Bodybuilt Labs SARMs PCT, SARMs Cycle Support and Testo Boost food supplements, Alpha Labs Armistane, and the Dexterz Labs PCT Stack. The Bodybuilt products are UK made food supplements formulated from plant extracts, amino acids, vitamins and minerals; they are not SARMs and not research compounds, and each product page lists the full ingredient panel per serving.
What PCT means in the research literature
Post cycle therapy is the term used for the period after an androgen receptor study protocol ends. The clinical SARM trials (Ostarine, LGD-4033, RAD-140) measured suppression of endogenous testosterone and LH during dosing and recovery afterwards; in most published trials hormone levels returned to baseline within weeks of stopping without intervention. Where suppression was deeper, clinicians used selective oestrogen receptor modulators, which are prescription medicines and not sold here. Our guide on what the research says about post cycle support sets out what has been studied and what has not, compound by compound.
What is in this range
SARMs PCT is a botanical and antioxidant formula built around ashwagandha extract, tribulus terrestris (90 percent saponins), rhodiola rosea, saw palmetto and vitamin E. SARMs Cycle Support is the on-cycle antioxidant and liver support formula: grape seed extract (95 percent proanthocyanidins), N-acetyl-L-cysteine, tribulus, saw palmetto, hawthorn berry, celery seed and vitamin E. Testo Boost is a five-extract testosterone support formula: tribulus, fenugreek, ashwagandha root, tongkat ali and stinging nettle root, suitable for vegans. Armistane (androsta-3,5-diene-7,17-dione) is an aromatase inhibitor supplied for research; it is not a food supplement. The PCT Stack bundles the support products at a lower combined price.
Choosing between them
The product pages set out ingredient panels and the studies behind each one. Cycle Support is the on-cycle liver and lipid formula; SARMs PCT and Testo Boost are the post-cycle testosterone support formulas; Armistane is the research aromatase inhibitor. The PCT guide maps each SARM's published suppression data to the support category researchers most often pair with it.

Frequently asked questions
What is the best PCT for SARMs?
The published trials show suppression varies by compound and study length: LGD-4033 and RAD-140 produced the deepest measured suppression, Ostarine the least at low study doses. The PCT guide sets out each compound's data so researchers can match support to the compound studied.
Do I need a PCT for Ostarine?
In the phase II Ostarine trials, testosterone returned to baseline after the study period without intervention at the doses used. Higher amounts have not been studied in humans. Read the guide before deciding.
Are these products SARMs?
No. SARMs PCT, Cycle Support and Testo Boost are UK made food supplements with published ingredient panels. Armistane is a research compound. None of them contains a SARM.
Can I buy PCT in the UK legally?
Yes. The Bodybuilt Labs products are food supplements sold under UK food law. Prescription SERMs such as tamoxifen and clomiphene are medicines and are not sold here.
Food supplements should not be used as a substitute for a varied diet. Do not exceed the stated serving. Not suitable for anyone under 18, or for pregnant or breastfeeding women.
