What Are SARMs?
Selective Androgen Receptor Modulators are a class of research compounds that bind to androgen receptors in specific tissues. Unlike traditional anabolic agents that flood the entire body with androgens, SARMs target muscle and bone tissue with greater selectivity. That tissue-selective mechanism is what makes them such an active area of pharmaceutical research.
Several SARMs have entered human clinical trials. Ostarine (MK-2866) completed Phase II and Phase III trials for muscle wasting and breast cancer. LGD-4033 (Ligandrol) completed Phase I trials for lean body mass. RAD-140 (Testolone) entered Phase I trials for breast cancer. These are not fringe compounds. They are active areas of clinical research published in peer-reviewed journals.
We sell SARMs strictly for research purposes only. Every product page links to the relevant clinical literature so researchers can make informed decisions based on published evidence, not marketing claims. Read our full guide to SARMs â

- LGD-4033 (Ligandrol). Phase I human trial data for lean body mass. Known for high binding affinity to androgen receptors. A staple in bulking research.
- YK-11 (Myostine). Acts as both a partial androgen receptor agonist and a myostatin inhibitor. Researched for its dual mechanism of action.
- Andarine S4. Originally developed by GTx Inc. Researched for effects on lean tissue and bone mineral density. Often used in cutting and recomposition protocols.
- ACP-105. A newer SARM with partial agonist activity. Researched as a potentially milder alternative with a favourable selectivity profile.
- RAD-150 (TLB-150). An esterified analogue of RAD-140 designed for improved stability and extended half-life in research applications.
Non-SARM Research Compounds
- MK-677 Ibutamoren. A growth hormone secretagogue (not a SARM) that stimulates GH and IGF-1 release. Human trial data available. Does not cause androgen receptor-mediated suppression. Popular in both bulking and recovery protocols.

Frequently Asked Questions About Buying SARMs in the UK
Where can I buy SARMs in the UK?
You can buy research-grade SARMs directly from sarms.co.uk. Every batch is independently HPLC tested and we publish full Certificates of Analysis for every product. We offer free next-day UK delivery via Royal Mail, plus international shipping. Avoid purchasing SARMs from general marketplaces like Amazon or eBay where quality standards are unverified.
Are SARMs legal in the UK?
Yes. SARMs are legal to buy and sell in the UK for research purposes. They are not controlled substances under the Misuse of Drugs Act. The Food Standards Agency classifies them as “novel food”, meaning they cannot be sold for human consumption. They are also on WADA’s prohibited list, so competitive athletes cannot use them. Read our full SARMs legality guide â
Are SARMs safe?
SARMs are research compounds, not approved medicines. Several have been through human clinical trials (Ostarine Phase II/III, LGD-4033 Phase I, RAD-140 Phase I), but long-term safety data is limited. SARMs that bind to androgen receptors can cause dose-dependent testosterone suppression. Read our full SARMs safety guide â
What is the best SARM for beginners?
Ostarine (MK-2866) is the most clinically studied SARM, with Phase II and III human trials completed. It has a moderate potency profile and is the most evidence-backed starting point. Our Beginner Muscle Stack pairs it with LGD-4033 for a well-researched introductory combination.
What is the best SARM for bulking?
RAD-140 (Testolone) and LGD-4033 (Ligandrol) have the strongest research profiles for lean mass. Both have human clinical trial data. Many researchers stack one of these with MK-677 (Ibutamoren) for growth hormone support. See our SARMs for bulking category.
What is the best SARM for cutting?
Ostarine MK-2866 is the most researched for lean tissue preservation during caloric restriction. Cardarine GW-501516 is commonly added for its metabolic research profile, and Andarine S4 is another option researched for recomposition. Browse our SARMs for cutting category.
Do SARMs require PCT (post cycle therapy)?
SARMs that act on androgen receptors (RAD-140, LGD-4033, Ostarine, YK-11, Andarine S4, ACP-105) can cause dose-dependent HPTA suppression. Non-SARM compounds like MK-677 and Cardarine do not require PCT. Read our full PCT guide â
How do I verify SARMs product quality?
Every product we sell is independently tested via HPLC by third-party UK laboratories. We publish full Certificates of Analysis for every batch, including chromatograms, not just purity percentages. We test raw materials before compounding and finished products after.

Yes. We accept Bitcoin and cryptocurrency payments alongside Visa, Mastercard, and direct bank transfer. Pay with Bitcoin or bank transfer and get 10% off your order. View all payment methods â
What is the difference between SARMs and steroids?
SARMs and anabolic steroids are fundamentally different compounds. SARMs selectively bind to androgen receptors in specific tissues, while steroids flood the entire body with androgens. SARMs are research compounds in clinical development; steroids are controlled substances in the UK. Read our SARMs vs Steroids guide â
How long does a SARMs cycle last?
Typical SARMs research cycles run 8 to 12 weeks depending on the compound and protocol. Milder compounds like Ostarine are often researched at 8-week cycles, while more potent compounds like RAD-140 are typically studied over 8 to 10 weeks. Read our full cycling guide â
