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, 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 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 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

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 a third-party laboratory, MZ Biolabs, and can be viewed below.

Dr. Jim Stoppani highlights the importance of acquiring SARMs from reputable companies that provide COAs, saying, “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.

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.

Product Range: 5/5

Sports Technology Labs’ SARMs are available in liquid and powder form.

2. Chemyo

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

Effectiveness: 5/5

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 also uses a third-party laboratory, S&N Labs, 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 at 30 mg/day, and Cardarine at 20 mg/day for six weeks, resulting in a 25-pound weight gain and a 30-pound increase in bench press strength after the first week. 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 forms. Each bottle contains 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
RAD-140	$69.99	10 mg/mL	500 mg (50 mL)
Ostarine	$59.99	25 mg/mL	1,250 mg (50 mL)
Ibutamoren	$69.99	25 mg/mL	1,250 mg (50 mL)
Cardarine	$54.99	10 mg/mL	500 mg (50 mL)
Andarine	$74.99	50 mg/mL	2,500 mg (50 mL)
YK-11	$74.99	10 mg/mL	500 mg (50 mL)
GW0742	$59.99	10 mg/mL	500 mg (50 mL)
S23	$54.99	20 mg/mL	600 mg (30 mL)
RU-58841	$54.99	50 mg/mL	1,500 mg (30 mL)

Pricing: 4.5/5

Initially, Chemyo’s SARMs appear to be priced standardly. However, when factoring in the additional volume in their vials and calculating the total milligram content, the overall cost may offer a potential advantage compared to other brands.

Payment, Shipping, and Communication: 4.5/5

Chemyo offers a range of payment options for researchers.

Accepted Payment Methods
Credit and debit cards

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 promotion has been discontinued.

They offer domestic shipping within the United States, 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 34 hours and 49 minutes.

Prompt communication is essential, as delays could present challenges for researchers if any issues arise with their orders. The illegal status of SARMs for human consumption may heighten this risk.

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, although 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, there is a possibility that some samples may not meet expected quality standards.

Product Range: 4.5/5

Amino Asylum’s SARMs are in liquid form.

Product	Price	Dose	Bottle Volume
Ostarine	$29.99	20 mg/mL	600 mg (30 mL)
MK-677	$54.99	25 mg/mL	750 mg (30 mL)
LGD-4033	$34.99	10 mg/mL	300 mg (30 mL)
RAD-140	$39.99	20 mg/mL	600 mg (30 mL)
S23	$34.99	25 mg/mL	750 mg (30 mL)
Andarine	$29.99	25 mg/mL	750 mg (30 mL)
YK-11	$39.99	10 mg/mL	300 mg (30 mL)
Cardarine	$44.99	25 mg/mL	750 mg (30 mL)
GW-0742	$49.99	15 mg/mL	450 mg (30 mL)

The only reason we have not awarded Amino Asylum a five-star rating for their product range is the absence of powdered SARMs, which some users prefer due to their cost-effectiveness.

Pricing: 5/5

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

Payment, Shipping, and Communication: 3/5

Amino Asylum has a 4% fee when purchasing by debit or credit card.

Shipping times can vary depending on the location of the researchers. Therefore, some packages arrive in just a few days, while others may have extensive delays. Amino Asylum also has a slow response time via email.

We have found that Amino Asylum does not consistently send a confirmation email for several days following a purchase. Therefore, there is generally no cause for concern if this occurs.

Amino Asylum Highlights

Pros:

• Lower-priced SARMs
• Most customers appear to be satisfied
• Excellent product selection

Cons:

• No COAs available
• Some customers report ineffective products
• 4% credit card fee
• Poor email communication

Update: On June 19, 2025, we received news that the FDA had shut down Amino Asylum.

Frequently Asked Questions

Which is the Best SARMs Company for Capsules?

Researchers may use Swiss Chems for clinical research purposes. They offer:

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

Our Swiss Chems packages typically arrive within 3 business days in the U.S. and within 8 days at our UK location.

Swiss Chems, however, can improve by offering:

• Liquid SARMs
• Cryptocurrency discount for researchers

Which British SARMs Company Does Inside Bodybuilding Recommend?

There are several SARM companies available for researchers in Great Britain to evaluate. UK SARMs provides 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 American SARM sources tend to be more effective and less costly compared to domestic companies. The quality differences are evidenced by the fact that fewer 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. We have found that delays are less likely with Swiss Chems, as it offers discreet packaging, enabling parcels to bypass customs without complications.

The main drawback of ordering from U.S. companies is longer shipping times for Canadian researchers due to international shipping.

Which SARMs Company Provides Shipping to 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 they possess licenses and approvals 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.

Is it Possible for SARMs to Cause Adverse Interactions?

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 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 used outside of research settings—such as by bodybuilders administering excessive dosages or engaging in prolonged 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, and 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 Consumers 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?

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

Sports Technology Labs exclusively ships within the U.S., ensuring that researchers receive their packages without issue. 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 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 Individuals 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 prior to 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 says that those with compromised ocular health should avoid SARMs, as he experienced significantly deteriorated vision during his cycle.

Are There Risks Associated With 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 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 when ordering 3 or more products.

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 closure 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?

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 declines.
• 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
• Guarantee of over 98% purity
• Extensive product selection
• Competitive pricing
• 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. These include a product purity of over 99% and a larger liquid volume per bottle, as confirmed by COAs. However, the absence of Stenabolic from their product range and a 7.95% credit card fee are drawbacks.

Amino Asylum may have been 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, claiming that they are “hepatotoxic” [16].

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