3 Best SARMs Companies in 2025 (>98% Purity)

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 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.

1. Sports Technology Labs (19/20)
2. Chemyo (17/20)
3. 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.

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.

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 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:

• Affordable SARMs
• Most customers are 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

Verdict

We have elected Sports Technology Labs as the best SARMs company in 2024 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.
