3 Best SARM Companies in 2026 (≥98% Purity)

Dr. Ramesh Narayanan, a leading researcher with firsthand experience regarding the effects of selective androgen receptor modulators (SARMs), states that they offer promise in treating cachexia, osteoporosis, and breast cancer.

However, the Journal of the American Medical Association (JAMA) found that 48% of SARMs are counterfeit, inadequately dosed, or substituted with inexpensive and hazardous substances [1].

Studies have indicated that SARMs have anabolic effects [2], but acquiring them can be risky because they are unregulated [3]. As a result, many rogue manufacturers have emerged, attempting to deceive customers with placebos.

According to Dr. Mike Israetel, “Counterfeit SARMs commonly contain anabolic steroids such as Winstrol (stanozolol) and Dianabol (methandrostenolone)” because they are cost-effective replacements. This practice may pose additional risks to researchers who source SARMs from untrustworthy firms.

We have also observed a shakeout in the SARMs manufacturing sector due to intensified Food and Drug Administration (FDA) scrutiny and COVID-19-related pressures, resulting in the closure of numerous companies.

Nevertheless, a select few organizations have endured the challenges and continue to operate. This is largely attributable to these sources operating with integrity and ethics while formulating efficacious SARM products.

The three best SARM companies, in our experience, are:

1. Sports Technology Labs: 19/20
2. Chemyo: 18/20
3. Amino Asylum: 16/20

We have rated each company based on the following criteria:

• Potency
• Product diversity
• Cost
• Payment options
• Delivery
• Communication

• Effectiveness: 5/5
• Product Range: 5/5
• Pricing: 4/5
• Payment, Shipping, and Communication: 5/5

Effectiveness: 5/5

Sports Technology Labs manufactures SARMs with a minimum purity of 98%, which contributes to its generally positive online reputation. Sports Technology Labs is among the few companies that provide Certificates of Analysis (COAs) for each of its products. MZ Biolabs, a third-party laboratory, conducts these COAs, as exemplified below.

Dr. Jim Stoppani highlights the importance of acquiring SARMs from reputable companies that provide COAs, stating, “It is a gamble not to know what is in the bottle.”

Researchers who administer SARMs from Sports Technology Labs may experience improved results in their studies due to higher purity levels and the absence of counterfeit or diluted products [4]. Below is an illustration of a subject’s transformation after using these products.

The above user received a 5-week course of Sports Technology Labs’ SARMs, consisting of the following daily doses:

• 5 mg of LGD-4033 (Ligandrol)
• 15 mg of RAD-140
• 25 mg of MK-677

They gained 16 pounds of lean mass while reporting exceptional increases in strength.

Considering that the user had previously used anabolic steroids, these results are noteworthy, as the potential for growth from SARMs is generally reduced in comparison to that of a natural weight trainer.

2. Chemyo: The Best Source for Customer Support

• Effectiveness: 5/5
• Product Range: 4/5
• Pricing: 4.5/5
• Payment, Shipping, and Communication: 4.5/5

Effectiveness: 5/5

Chemyo offers products with a minimum chromatographic purity exceeding 99%. Achieving such levels of purity is accomplished through the process of recrystallization [5].

Chemyo commissions an independent laboratory, S&N Labs, to verify the purity of its products.

The high purity levels of Chemyo’s products are also reflected in consistently positive customer feedback.

The above subject utilized Chemyo products at the following daily doses for six weeks:

• 25 mg of Ostarine
• 30 mg of RAD-140 (vosilasarm)
• 20 mg of Cardarine

This resulted in a 25-pound weight gain and a 30-pound increase in bench press strength after the first week. These results exceed the typical expectations associated with SARM use.

Factors that may have contributed to this outcome, such as the user’s training schedule and nutrition, are not specified.

Product Range: 4/5

Chemyo offers its products in both liquid and powder forms. Most bottles contain 50 milliliters compared to the industry standard of 30 milliliters.

The sole drawback of Chemyo’s product line is the exclusion of LGD-4033, which was discontinued due to a cease-and-desist letter from the patent holder. Additionally, Stenabolic (SR9009) is no longer available for purchase.

Product	Price	Dose	Bottle Volume
1. RAD-140	$69.99	10 mg/mL	500 mg (50 mL)
2. Ostarine	$59.99	25 mg/mL	1,250 mg (50 mL)

8. S23	$54.99	20 mg/mL	600 mg (30 mL)
9. RU-58841	$54.99	50 mg/mL	1,500 mg (30 mL)

Pricing: 4.5/5

Chemyo’s SARMs are generally priced in accordance with industry standards. However, when considering the increased volume contained within their vials and calculating the total milligram content, the overall cost may present a comparative advantage relative to other brands.

Payment, Shipping, and Communication: 4.5/5

Chemyo provides a variety of payment options for researchers, which are outlined below.

Accepted Payment Methods
Credit and debit cards
Bitcoin
Solana

A notable limitation is the 7.95% surcharge incurred when making purchases via credit card. This fee percentage exceeds those charged by several other SARM providers. However, it is important to note that this surcharge is not applicable to customers utilizing Bitcoin as their payment method.

Chemyo previously offered a 10% discount for payments made via cryptocurrency; however, this promotion has been discontinued.

They offer domestic shipping within the U.S., with orders typically arriving in 2–5 days.

We tested Chemyo’s customer response time via email. We sent a message to Chemyo at 6:25 am on July 2, 2025, and its team replied at 5:14 pm on July 4. Thus, Chemyo responded to our query in 58 hours and 49 minutes.

Prompt communication is crucial in academic and research settings, as delays can pose significant challenges for investigators if issues arise with their orders. The unauthorized use of SARMs for human consumption, which is illegal in many jurisdictions, may exacerbate this risk, potentially resulting in unforeseen consequences for researchers and their projects.

Chemyo Highlights

Pros:

• Over 99% purity
• COAs provided
• Higher volume of liquid per bottle
• Prompt customer support

Cons:

• No Stenabolic product available

7. YK-11	$39.99	10 mg/mL	300 mg (30 mL)
8. Cardarine	$44.99	25 mg/mL	750 mg (30 mL)
9. GW-0742	$49.99	15 mg/mL	450 mg (30 mL)

The sole factor preventing us from assigning a five-star rating to Amino Asylum’s product range is the absence of powdered SARMs, which are preferred by some consumers due to their cost-effectiveness.

Pricing: 5/5

Amino Asylum’s pricing is significantly more affordable than other SARM brands, making it an attractive option for researchers fortunate enough to receive authentic products. Nevertheless, there is a risk of obtaining subpar formulations, as Amino Asylum’s SARMs lack independent third-party testing to verify their quality and potency.

Frequently Asked Questions

What is the Best Company for SARM Capsules?

We have found Swiss Chems to be the best company for SARM capsules, as it offers:

• A guaranteed minimum product purity of 99%
• Worldwide delivery and discreet shipping

Our Swiss Chems packages typically arrive at our UK address one week after the order is placed.

Swiss Chems, however, can improve by offering:

• Liquid SARMs
• Cryptocurrency discount for researchers

Which English SARMs Company Does Inside Bodybuilding Recommend?

There are several high-quality SARM companies in England. However, in our experience, the best is UK SARMs.

UK SARMs offers a selection of liquid products with purity levels exceeding 99%.

Although we have found UK SARMs products to be effective, they are priced at a premium.

What is the Best Source of SARMs in Canada?

Our Canadian patients have reported that U.S. SARM sources, on average, are more effective and less costly than domestic companies. The disparities in quality are evidenced by the observation that a smaller number of Canadian companies provide COAs.

Sports Technology Labs does not ship to Canada. However, Chemyo and Swiss Chems products can be utilized by Canadian researchers, with both companies formulating SARMs at over 99% purity.

Chemyo manufactures liquid SARMs, while Swiss Chems produces capsules. Our findings indicate that delays are less prevalent with Swiss Chems, attributable to its provision of discreet packaging, which facilitates the smooth passage of parcels through customs without complications.

The primary disadvantage for Canadian researchers ordering SARM products from U.S. companies is the comparatively longer shipping times relative to domestic sources.

Which SARM Companies Provide Shipping to Researchers in Australia?

Australian researchers can successfully receive orders from Swiss Chems and UK SARMs, thanks to their discreet shipping methods.

However, researchers should be aware that SARMs are only legal for studies in Australia when accompanied by a license and approval from the Therapeutic Goods Administration (TGA). As a result, several companies have ceased shipping to Australia due to legal concerns and the requirement of an import permit.

Have SARMs Caused Adverse Interactions in Studies?

Yes, research has indicated that SARMs can lead to several negative effects, including:

• Androgenetic alopecia
• Edema
• Testosterone suppression and hypogonadism [6]
• Cholesterol alterations [7]
• Hypertransaminasemia [8]

Efimenko et al. found that 44% of SARM users do not report any side effects, while 56% experience symptoms such as mood swings, acne, and testicular atrophy [9].

Research indicates that the aforementioned side effects are generally transient and improve once supplementation is discontinued [10]. However, declines in long-term health remain possible, especially when used outside of research settings—such as by bodybuilders administering excessive dosages or engaging in prolonged cycles [11].

A 2023 case study [12] reports that prolonged use of SARMs led to a diagnosis of jaundice in an individual.

Furthermore, Christiansen et al. (2020) suggest that some users may not report any obvious side effects [13]. Thus, toxicity appears to be related to:

• The dosage administered
• The duration of the cycle
• The use of potentially hepatotoxic medications in conjunction with SARMs

Dr. Thomas O’Connor, who has over two decades of experience treating patients exposed to performance-enhancing drugs (PEDs), including SARMs, states that their level of toxicity rivals that of various anabolic steroids. Dr. Touliatos has also observed the effects of SARMs on bodybuilders under his care and says they have the potential to impair the hypothalamic-pituitary-testicular axis (HPTA), causing low testosterone.

What Should Researchers Know When Navigating the SARMs Market?

Companies that do not offer COAs or provide purity guarantees are more likely to be ineffective [14]. However, researchers should be aware that COAs can also be forged. Therefore, such documents should be verified by contacting the third-party laboratory that conducts the purity tests.

What Ethical Concerns Are Associated With Various SARM Companies?

Currently, regulatory authorities have not approved SARMs for human consumption [15]. Therefore, products in capsule form may raise concerns among regulators. Furthermore, they may shut down websites that feature reviews from bodybuilders utilizing these products for cosmetic purposes.

The FDA also warns that numerous websites are selling SARMs to minors, which could potentially disrupt their natural development and hormonal balance later in life.

Which SARM Companies Guarantee Delivery to Researchers?

Chemyo guarantees delivery and commits to reshipping orders that fail to arrive.

Sports Technology Labs exclusively ships within the U.S., thereby ensuring reliable delivery to researchers. Policies among other SARM companies may vary.

What Are the Indicators of a Fraudulent SARMs Company?

Researchers should be skeptical of a source that:

• Does not supply customers with third-party COAs
• Does not disclose company information
• Has received numerous negative reviews online

Why Are There No Dosage Guidelines on SARMs Company Websites?

Companies must exercise caution when marketing SARMs outside of research settings. Therefore, they often do not disclose dosage recommendations to safeguard their business from regulatory authorities.

Are Researchers Required to Have a Prescription Before Ordering SARMs?

In most countries, SARMs are classed as research chemicals. Therefore, due to a lack of approval, prescriptions are not required before purchase. However, in Australia, SARMs are illegal without a valid prescription.

Can an Individual Utilize SARMs if They Have a Health Condition?

In the U.S. and the UK, SARMs are illegal for human consumption outside of an authorized trial. Furthermore, they can exacerbate a user’s health, especially if there is an existing condition relating to:

• Heart health
• Liver health
• Testosterone levels

However, we do not currently understand the full effects of SARMs or their potential contraindications.

Ex-bodybuilder Victor Martinez states that individuals with compromised ocular health should avoid SARMs, as he experienced significantly deteriorated vision during his cycle.

Are There Risks Associated With Individuals Importing SARMs?

Based on our patient feedback, SARM imports are rarely seized or result in warnings from authorities. However, for researchers in Australia, where laws are more stringent, importing SARMs poses a greater risk.

Do SARM Companies Offer Bulk or Wholesale Options?

Yes, numerous SARM companies offer bulk or wholesale purchase options. For example, Sports Technology Labs offers a 50% discount for researchers who order 50 or more items.

Chemyo offers a 10% discount on orders of 3 or more products.

UK SARMs customers can also save 20% when ordering 9 or more items.

What Are the Reasons Behind the Closure of Various SARM Companies?

SARM companies that promote human consumption outside of research are at risk of being closed down by domestic authorities. This applies to, but is not limited to, their website and social media content.

Is it Advisable for Individuals to Discontinue SARM Supplementation Abruptly?

Humans in clinical trials should adhere to the advice of medical professionals overseeing the study. In such settings, users typically cease taking SARMs entirely rather than tapering their dosage when discontinuing use.

Are There Any Licensed SARM Companies?

SARMs are not approved as medicines; consequently, there are currently no licensed companies producing them.

Can SARM Capsules Indicate Human Consumption?

SARM companies that sell capsules may be more vulnerable to scrutiny from regulatory authorities. However, such companies may contend that capsules can be utilized in clinical research settings.

Where Can Researchers Send a SARM Sample for Testing?

Researchers may test the purity of a SARM sample by sending it to any of the following laboratories:

• Janoshik Analytical
• MZ Biolabs
• Eurofins Scientific

These firms conduct high-performance liquid chromatography (HPLC) and mass spectrometry tests to determine the identity and purity of the compound.

Can SARM Companies Falsify COAs?

Yes, SARM companies may provide COAs that obscure the laboratory or the scientist conducting the test.

Additionally, COAs can be photoshopped or generated with artificial intelligence. Therefore, researchers are advised to contact the laboratory to verify the authenticity of the certificate.

Safety Information

• Researchers are encouraged to verify COAs by contacting third-party laboratories directly.
• SARMs should not be exposed to direct sunlight and must be stored in a dry area to prevent degradation.
• The content in this article is not a substitute for a doctor’s consultation or medical advice.
• The abuse of SARMs may lead to psychological dependency.
• Users should undergo regular health check-ups with a physician to prevent potential health deterioration.
• Regarding dosing, users should follow the instructions provided by the medical professionals overseeing the trial.

Verdict: Which is the Best SARMs Company?

We have selected Sports Technology Labs as the best SARMs company in 2026 for users seeking effective SARMs, awarding them a score of 19 out of 20.

This score is based on Sports Technology Labs’:

• Provision of COAs
• 98% purity guarantee
• Extensive product selection
• Competitive pricing
• Positive checkout experience

However, Sports Technology Labs can improve by enabling researchers outside the U.S. to access its products.

Chemyo is potentially the most prominent name in the SARMs niche, offering several benefits, including over 99% product purity and a larger liquid volume per bottle, as confirmed by its COAs. However, the absence of Stenabolic from Chemyo’s product range and a 7.95% credit card fee are drawbacks.

Amino Asylum is one of the most reputable SARM providers for researchers operating within limited budgets and willing to assume a higher level of risk.

Irrespective of the company from which an individual purchases SARMs, Dr. Thomas O’Connor states that he has observed “steroid-like side effects” in SARM users under his care. The FDA has echoed his concerns, warning that SARMs are “hepatotoxic” [16].

Dr. O’Connor adds that health-conscious individuals “should not take any SARMs or steroids,” as they can cause cardiac and hepatic issues, including atherosclerosis and cholestasis [17, 18].
