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

Dr. Ramesh Narayanan is a leading researcher with firsthand experience regarding the effects of selective androgen receptor modulators (SARMs). He states that they offer promise in treating:

• Cachexia
• Osteoporosis
• Breast cancer

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

Although studies have shown SARMs to have anabolic effects [2], acquiring them can be risky due to their unregulated nature [3]. Consequently, numerous rogue manufacturers have emerged, attempting to shortchange 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 scammy practice may pose additional risks to researchers who source SARMs from untrustworthy firms.

We have 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 relying on integrity and ethics while formulating efficacious SARM products.

The three best SARM companies, based on our patient feedback, are:

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

Our patients have rated each company based on the following criteria:

• Effectiveness
• Product range
• Pricing
• Payment, shipping, and communication

1. Sports Technology Labs

• 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. These COAs are conducted by MZ Biolabs, a third-party laboratory holding a U.S. Drug Enforcement Administration Schedule III license.

Dr. Jim Stoppani highlights the importance of researchers acquiring SARMs from companies that provide COAs. He states that “it is a gamble” not to know what is in the bottle.

Researchers utilizing 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 5 mg/day of LGD-4033 (Ligandrol), 15 mg/day of RAD-140, and 25 mg/day of MK-677. He gained 16 pounds of lean mass while reporting exceptional increases in strength.

These results are noteworthy considering that the user had previously used anabolic steroids. For individuals who have historically used anabolic agents, the potential for growth from SARMs is less in comparison to that of a natural weight trainer.

Chemyo has efficacious products with a minimum chromatographic purity of over 99%. Such levels of purity are possible via the process of recrystallization [5].

Chemyo uses Colmaric Analyticals, an ISO/IEC-certified and ISO-accredited laboratory, to authenticate the purity of its products.

The high purity levels of Chemyo’s products also correlate with consistently positive customer feedback.

The above subject utilized Chemyo’s Ostarine at 25 mg/day, RAD-140 (vosilasarm) at 30 mg/day, and Cardarine at 20 mg/day for six weeks. He gained 25 pounds of weight and added 30 pounds to his bench press after the first week. Based on our observations, these results are above average for SARM use.

Factors that may have contributed to this outcome, such as his training schedule and nutrition, are not specified.

Product Range: 4/5

Chemyo offers its products in both liquid and powder form. 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 (Ligandrol), 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)

One drawback is the 7.95% fee added when purchasing with a credit card. This percentage is higher than what several other SARMs companies charge. However, this fee does not apply to customers purchasing with Bitcoin.

Chemyo previously offered a 10% discount for payments made via cryptocurrency; however, this 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 them a message at 6:25 am on July 2, 2025, and they replied at 5:14 pm on July 4. Thus, Chemyo responded to our query in 58 hours and 49 minutes.

Prompt communication is essential, as delays can present challenges for researchers, especially given the illegal status of SARMs for human consumption.

Chemyo Highlights

Pros:

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

Cons:

• No Stenabolic product available
• 7.95% credit card processing fee

3. Amino Asylum

• Effectiveness: 3.5/5
• Product Range: 4.5/5
• Pricing: 5/5
• Payment, Shipping, and Communication: 3/5

Effectiveness: 3.5/5

Amino Asylum’s products are generally well-received. However, some customers on Reddit have described the company as “hit and miss” and expressed concerns regarding product potency.

Thus, while the majority of customers may receive authentic SARMs from Amino Asylum, some samples do not meet expected quality standards.

Product Range: 4.5/5

Amino Asylum’s SARMs are in liquid form.

Product	Price	Dose	Bottle Volume
1. Ostarine	$29.99	20 mg/mL	600 mg (30 mL)
2. MK-677	$54.99	25 mg/mL	750 mg (30 mL)
3. LGD-4033	$34.99	10 mg/mL	300 mg (30 mL)
4. RAD-140	$39.99	20 mg/mL	600 mg (30 mL)

Frequently Asked Questions

What is the Best Company for SARM Capsules?

Our patients have found Swiss Chems to be the best company for SARM capsules, as they offer:

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

According to our UK patients, Swiss Chems packages typically arrive one week after the order is placed.

Swiss Chems, however, can improve by offering:

• Liquid SARMs
• Cryptocurrency discount for researchers

What English SARMs Company Does Inside Bodybuilding Recommend?

There are several high-quality SARM companies in England, with our patients stating UK SARMs to be the most effective source. They offer a vast range of liquid products with purity levels exceeding 99%.

Although our patients have found UK SARMs products to be high-quality, 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 tend to be more effective and less costly compared to domestic companies. The quality differences are evidenced by fewer Canadian companies providing COAs.

Sports Technology Labs does not ship to Canada. However, Chemyo and Swiss Chems are high-quality companies accessible to Canadian researchers, both formulating SARMs at over 99% purity.

Chemyo manufactures liquid SARMs, while Swiss Chems produces capsules. Our patients have found that delays are less likely with Swiss Chems, as they offer discreet packaging, enabling parcels to bypass customs without complications.

The main drawback for Canadian researchers ordering from U.S. companies is extended shipping times, compared 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 with a license and approval from the Therapeutic Goods Administration (TGA). As a result, several companies have ceased shipping to the country 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:

1. Androgenetic alopecia
2. Edema
3. Testosterone suppression and hypogonadism [6]
4. Cholesterol alterations [7]
5. 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
• Testicular atrophy [9]

Research indicates that these side effects are often transient and tend to improve once supplementation is discontinued [10]. However, declines in long-term health remain possible, especially when SARMs are used outside of research settings. One cosmetic example is weightlifters administering excessive dosages or engaging in extensive cycles [11].

Following prolonged use of SARMs, an individual was diagnosed with jaundice, as reported in a 2023 case study [12]. However, 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 has over two decades of experience treating patients who have used performance-enhancing drugs (PEDs), including SARMs. He states that SARMs’ level of toxicity rivals that of various anabolic steroids.

Dr. Touliatos has also observed the effects of SARMs on bodybuilders under his care. He warns that they have the potential to impair the hypothalamic-pituitary-testicular axis (HPTA), causing low testosterone.

The FDA warns that SARMs may pose serious health risks, including the potential for fatal outcomes. Similarly, the Cleveland Clinic emphasizes that these substances can be life-threatening.

What Should Researchers Know When Navigating the SARMs Market?

Our patients state that companies failing to provide COAs or purity guarantees are more likely to be ineffective [14]. However, researchers should be aware that COAs can also be forged. Therefore, we recommend that test reports be verified by contacting the third-party laboratory directly.

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, authorities 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., increasing the likelihood that researchers receive their packages without issues.

However, policies among other SARM companies often vary.

What Are the Indicators of a Fraudulent SARMs Company?

Researchers should be skeptical of a source that:

1. Does not supply customers with third-party COAs
2. Does not disclose company information
3. Has received numerous negative reviews online

Why Are There No Dosage Guidelines on Company Websites?

Companies must exercise caution when marketing SARMs outside of research settings. Therefore, they 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 they have 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 warns that those with compromised ocular health should avoid SARMs. This recommendation is the result of Martinez experiencing impaired vision during supplementation.

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, in countries with more stringent laws, importing SARMs could pose 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 items.

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

Why Are Various SARM Companies Being Shut Down?

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 SARMs Abruptly?

Participants in clinical trials are expected to follow the guidance of the medical professionals supervising the study. In these settings, individuals usually stop using SARMs immediately rather than tapering their dosage gradually before discontinuation.

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 are utilized in clinical research settings.

Where Can Researchers Send SARM Samples for Testing?

Researchers may test the purity of SARM samples by sending them to any of the following laboratories:

1. Janoshik Analytical
2. MZ Biolabs
3. Colmaric Analyticals
4. Eurofins Scientific

These firms conduct high-performance liquid chromatography (HPLC) and mass spectrometry (MS) 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

• 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: What is the Best SARMs Company?

Our patients have selected Sports Technology Labs as the best SARMs company for research in 2026.

This score is based on Sports Technology Labs’:

1. Provision of COAs
2. Guarantee of over 98% purity
3. Extensive product selection
4. Competitive pricing
5. Positive checkout experience

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

Chemyo is potentially the most prominent name in the SARMs niche, offering several benefits, including:

• Over 99% purity
• International shipping
• More volume per bottle

However, the absence of Stenabolic from their product range and a 7.95% credit card fee are drawbacks.

Amino Asylum is one of the most reputable SARM providers for researchers with limited budgets who are 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 users under his care. The FDA has echoed his concerns, claiming that they are “hepatotoxic” [16].

Dr. O’Connor adds that health-conscious individuals “should not use any SARMs or steroids” to avoid developing atherosclerosis or cholestasis [17, 18].
