Disclaimer: Individuals should only use SARMs for research purposes, as they are not FDA-approved and may have adverse effects. Dr. Touliatos is available for consultation should readers have any questions or concerns.
Research by the JAMA network indicated that 48% of SARMs are either counterfeit, inadequately dosed, or substituted with inexpensive and hazardous substances (1).
Although SARMs have anabolic effects, acquiring them may be risky due to their unregulated nature. Consequently, numerous rogue manufacturers have emerged attempting to shortchange customers with placebos.
According to Dr. Mike Israetel, SARMs commonly contain cheap anabolic steroids like “Winstrol” and “Dianabol” due to them being cost-effective replacements. This may pose additional risks to researchers who source SARMs from untrustworthy firms.
We have also seen a shakedown in the SARMs manufacturing sector due to FDA scrutiny intensifying (2) and COVID-19 pressure, resulting in the closure of numerous companies. Nevertheless, a select few organizations have endured the challenges and continue to operate. This is mostly attributable to these sources operating with integrity and ethics while formulating efficacious SARM products.
Below are the three best SARM companies in our experience. We have rated each based on potency, product diversity, cost, payment options, delivery, and communication.
- Sports Technology Labs (19/20)
- Chemyo (17/20)
- Amino Asylum (16/20)
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%, contributing to a generally positive online reputation.
They are one of the few companies that provide COAs (certificates of analysis) for each product. These certificates are conducted by a third party, Colmaric Analyticals (3). We have a source who contacted Colmaric Analyticals to verify the accuracy of the COAs for Sports Technology Labs.
Dr. Jim Stoppani highlights the importance of acquiring SARMs from reputable companies that provide certificates of analysis, saying, “It is a gamble” to not know what is in the bottle.
Customers utilizing SARMs from Sports Technology Labs may experience improved results due to higher purity levels and the absence of counterfeit or diluted products. Below is an illustration of a customer’s transformation after using these products.
The above Reddit user completed a cycle of Sports Technology Labs’ SARMs. He utilized a 5-week cycle consisting of 5 mg/day of LGD-4033, 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 steroids, these results are noteworthy, as the potential for growth from SARMs is reduced in comparison to that of a natural weight trainer.

Sports Technology Labs’ SARMs come in liquid or powder form.

Researchers have posted the following reviews on Facebook regarding Sports Technology Labs’ SARMs.
I have to say that Sports Technology Labs came in clutch with 3-day delivery and amazing products. Highly recommend.
I only order from them and always get good products, and the delivery time is great. A bit pricey but worth the money.
Sports Technology Labs is 100% legit.
2. Chemyo
- Effectiveness: 5/5
- Product Range: 4/5
- Pricing: 4.5/5
- Payment, Shipping, and Communication: 3.5/5
Effectiveness (5/5)
Chemyo has efficacious products with a minimum chromatographic purity of over 99%. Such levels of purity are only possible via the process of recrystallization (4).
Chemyo also uses a third-party company (S and N Labs) to authenticate the purity of their products.
The high purity scores of Chemyo’s products also correlate with their customers’ consistently positive results.
A Reddit user’s results from Chemyo’s SARMs
The user took Chemyo’s ostarine (25 mg/day), RAD 140 (30 mg/day), and cardarine (20 mg/day) for 6 weeks, resulting in a 25-pound weight increase and a 30-pound boost to his bench press 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 liquid and powder form. Each bottle contains 50 milliliters compared to the industry standard of 30 milliliters.
The sole drawback of their product line is the exclusion of LGD-4033, which was discontinued as a result of a cease-and-desist letter from the patent proprietor. Additionally, Stenabolic is no longer available for purchase.
| Product | Price | Dose | Volume per bottle |
|---|---|---|---|
| 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, the pricing of Chemyo’s SARMs appears to be standard. However, when considering the additional volume in their vials and calculating the total milligram quantity, a comparison may suggest a potential cost advantage.
Payment, Shipping, and Communication (3.5/5)
Chemyo offers a variety of payment options.
| Accepted payment methods |
|---|
| Credit and debit card (via Max Redemption) |
| Bitcoin |
| Solana |
One drawback with Chemyo is that they add a 7.95% fee when purchasing by credit card. This is a higher percentage compared to other SARM companies. However, this charge does not apply to customers purchasing with Bitcoin.
Chemyo previously offered a 10% discount when paying via cryptocurrency; however, this has been eradicated.
Chemyo offers domestic shipping, with orders in the United States typically arriving within 2–5 days.
In terms of communication, Chemyo delayed responding to our initial email by nearly a week. We had to send a follow-up email before receiving a response. After more than a week of waiting, Chemyo also failed to respond to our most recent email. Delays in communication could pose a challenge for consumers in the event that any complications arise with their orders.
Chemyo Pros:
- Very high purity, over 99%
- COAs provided
- Higher volume of liquid per bottle
Chemyo Cons:
- No LGD-4033 or Stenabolic products
- 7.95% credit card fee
- Delayed or absent email support
Feedback from Chemyo customers can be seen below (source: Facebook).
I just ordered Chemyo’s MK 677 and MK 2866 stack; so far I’m loving it!
Chemyo is the real deal. Legit, easy, and fast shipping!
Chemyo is the bomb. I love the research I’ve done with them.
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 among the weightlifting community, although some customers on Reddit have described them as “hit and miss” and expressed concerns regarding product potency.”
Here is a review published on Facebook by a customer:
I purchased 4 times, and the last time was bunk; therefore, onwards, I stopped using them.
He later reported that Amino Asylum’s clenbuterol product was ineffective. He then experimented with another brand of clenbuterol at a reduced dose and observed an instant change.
Thus, while the majority of customers may receive authentic SARMs from Amino Asylum, there is a possibility that some samples may not meet the expected quality standards.
Product Range (4.5/5)
Amino Asylum’s SARMs are in liquid form.
| Product | Price | Dose | Volume per bottle |
|---|---|---|---|
| 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) |
Their product range also includes several peptides, prohormones, and post-cycle therapy supplements.
The sole reason we have not awarded Amino Asylum a five-star rating for their product range is that powdered SARMs are not available.
Pricing (5/5)
Amino Asylum’s pricing is significantly less expensive than that of other SARM brands. Thus, they are an appealing source for fortunate researchers who receive authentic SARMs. Nevertheless, there is a possibility of obtaining subpar formulations with no independent third-party testing.
Payment, Shipping, and Communication (3/5)
| Accepted payment methods |
|---|
| Credit and debit card |
| Zelle |
Amino Asylum has a 4% fee when purchasing by debit and credit card.
Shipping times can vary depending on where researchers are located, with some packages arriving in just a few days and others experiencing extensive delays, with slow correspondence via email.
We find that Amino Asylum does not consistently send a confirmation email for several days following a purchase. Therefore, there should be no cause for concern if this happens.
Amino Asylum Pros:
- Lower-priced SARMs
- Most customers appear to be satisfied.
- Excellent product selection
Amino Asylum Cons:
- No certificates of analysis
- A few customers complain of ineffective products.
- 4% credit card fee
- Poor email communication
Frequently Asked Questions
What is the Best SARMs Company for Pills?
The most common company our patients utilize for SARM capsules is Swiss Chems. We have tested their product purity, with it recording over 99%. They offer worldwide delivery and discreet shipping, making their SARMs accessible worldwide. Our packages commonly arrive within 3 business days when in the US and 8 days for our UK location.
Swiss Chems, however, can improve by offering liquid SARMs or offering a cryptocurrency discount for researchers.
What is the Best Company for UK Researchers?
When evaluating SARMs companies for researchers in the UK, several options are available based on personal experience. uksarms.com provides a selection of liquid SARMs products, which we have tested and found to have purity levels exceeding 99%.
While their products have demonstrated consistent performance, they are priced at a premium level. For those who prefer capsules, we have also received positive feedback on products from Peak Body, which may offer a convenient alternative for some users.
What is the Best SARM Source in Canada?
Our Canadian patients have reported American SARM sources to be more effective and less costly compared to domestic companies. Quality differences can be evidenced by fewer Canadian companies providing certificates of analysis.
Sports Technology Labs does not ship to Canada; however, Chemyo and Swiss Chems can be utilized by Canadian researchers, with both companies formulating products at over 99% purity in our testing. Chemyo manufactures liquid SARMs and Swiss Chems capsules. We have found delays are less likely to occur with Swiss Chems, as they offer discreet packaging, enabling parcels to bypass customs without complications.
The main drawback to ordering from US companies is that they will take longer to arrive for Canadian researchers due to them being shipped internationally.
Do Any SARM Companies Ship to Australia?
Yes, our Australian patients have received Swiss Chems and UK SARMs orders with success due to their respective stealth shipping methods.
However, researchers should be aware that SARMs are only legal in Australia when accompanied with a prescription. Consequently, several companies have ceased shipping to the country due to legal concerns, and orders can be seized when they are not discreetly packaged.
Is It Possible for SARMs to Induce Adverse Interactions?
Yes, we have observed negative effects and toxicity in SARM users, such as:
- Hair thinning
- Water retention
- Testosterone suppression
- Cholesterol alterations
- Elevated liver enzymes
We find these side effects can be transient, commonly improving once supplementation is discontinued. However, declines in long-term health remain possible, particularly when users administer excessive dosages or extensive cycles.
Two of our patients were diagnosed with hepatic peliosis and jaundice following high dosages of SARMs. Other users may not report any obvious side effects. Thus, toxicity appears to be related to dosage, cycle duration, and potential hepatotoxic medications used in tandem with SARMs.
What Should Consumers Be Aware of When Navigating the SARMs Market?
In our testing, companies that do not offer certificates of analysis or provide purity guarantees are more likely to be ineffective.
What Ethical Concerns Are Associated With Some SARMs Companies?
SARMs for human consumption are prohibited in many countries. Therefore, products in capsule form may raise concerns among regulatory authorities. Furthermore, they may shut down websites that receive reviews from bodybuilders who utilize the products for cosmetic purposes.
Verdict: What is the Best SARMs Company?
We have elected Sports Technology Labs as the best SARMs company in 2025 for researchers seeking effective SARMs, with a score of 19/20.
This score is based on Sports Technology Labs’ provision of COAs, guaranteeing over 98% purity, vast product selection, competitive pricing, and a positive checkout experience.
However, Sports Technology Labs can still improve by providing a way for non-US researchers to access their products.
Chemyo is potentially the most prominent name in the SARM niche, and they possess their own benefits. These consist of a product purity of over 99% and a greater liquid volume per bottle, as confirmed by COAs. However, due to the absence of Stenabolic and LGD-4033 from their product range, a hefty 7.95% credit card fee, and untimely email responses, there remains room for improvement.
Amino Asylum may still be the best SARMs company for those on a budget and willing to take a risk. For customers who receive effective products, purchasing from Amino Asylum may result in short-term financial savings.
Irrespective of what company an individual may purchase SARMs from, Dr. Thomas O’Connor states that he has observed “steroid-like side effects” in SARM users under his care. He adds that health-conscious individuals “should not take any SARMs or steroids” to eliminate cardiac and hepatic risks.
