Behemoth Labz or Swiss Chems: Who Offers the Best SARM Stacks in 2025?

For bodybuilders and researchers aiming to optimize muscle growth, fat loss, and recovery, Selective Androgen Receptor Modulator (SARM) stacks are a powerful tool. With numerous vendors in the market, choosing the best place to buy SARM stacks online is critical. Behemoth Labz, our brand, stands out as a premier supplier, delivering unmatched quality, variety, and customer support. While Swiss Chems is a known competitor, it falls short in several key areas. This article compares Behemoth Labz and Swiss Chems, highlighting why our brand leads the industry for SARM stacks in 2025, with product details, user feedback, ratings, and safe usage guidelines.

Why Behemoth Labz Excels in SARM Stacks

Behemoth Labz, established in 2014, is a U.S.-based leader in SARMs, peptides, and stacks, renowned for its commitment to purity, innovation, and customer satisfaction. Here’s why Behemoth Labz is the top choice for SARM stacks:

• Superior Quality: Every stack, such as the Gorilla Capsules (MK-2866, MK-677, LGD-4033, RAD-140, GW-501516), undergoes rigorous third-party testing by Colmaric Analyticals LLC, achieving 99.5%+ purity. This ensures researchers and athletes receive potent, reliable compounds.
• Diverse Product Range: Behemoth Labz offers stacks in capsules, liquids, and injectables, catering to varied needs. From bulking stacks like LGD-4033 + RAD-140 to cutting stacks with Cardarine, their catalog is comprehensive.
• Customer-Centric Service: Free U.S. shipping on orders over $150, a 15% discount with code “MD15,” and 24-hour support via live chat, phone, and email set Behemoth Labz apart. A 2024 Yahoo Finance review praised their “unmatched customer trust.”
• Innovative Formulations: Stacks like Post Cycle Max include Arimistane and NAC for recovery, offering a complete solution for post-cycle therapy (PCT) that competitors lack.
• U.S.-Based Manufacturing: Produced in GMP-certified Texas facilities, Behemoth Labz ensures strict quality control and fast shipping, unlike competitors reliant on overseas suppliers.

Rating: ★★★★★ (5/5 stars for purity, variety, and service)

Swiss Chems: A Competitor with Shortcomings

Swiss Chems, founded in 2018 in New York, is a recognized SARM supplier focusing on capsules. While it has a decent reputation, it lags behind Behemoth Labz in critical areas:

• Limited Catalog: Swiss Chems does not offer LGD-4033 or MK-2866 due to trademark restrictions, limiting stack options compared to Behemoth Labz’s extensive range, including Gorilla Capsules for bulking.
• Higher Costs: Swiss Chems’ pricing is less competitive, with lower mg-per-bottle value. For example, their 30 ml RAD-140 bottle is pricier per mg than Behemoth Labz’s 35 ml bottle.
• Capsule-Only Focus: Swiss Chems primarily sells SARMs in pill form, lacking the flexibility of Behemoth Labz’s liquids and injectables, which researchers prefer for precise dosing.
• Testing Gaps: While Swiss Chems provides COAs, their testing protocols are less consistent, as noted in a 2025 Inside Bodybuilding review. Behemoth Labz’s batch-specific, 99.5%+ purity reports are superior.
• Payment Limitations: Swiss Chems charges a 5% fee for credit card payments and restricts international customers to Bitcoin, whereas Behemoth Labz accepts multiple methods (including PayPal with caution) without fees.

Rating: ★★★☆☆ (3/5 stars for quality but limited range and higher costs)

A 2022 Reddit user (u/BeDark0) reported impurities in Swiss Chems’ products, reinforcing Behemoth Labz’s edge in quality assurance.

Popular SARM Stacks from Behemoth Labz

Behemoth Labz’s stacks are tailored for specific goals, offering pre-formulated solutions for researchers and athletes. Below is a comparison of their top stacks:

• Gorilla Capsules: Combines five potent SARMs for maximum muscle growth and strength, ideal for bulking. Users report 8-12 pounds of lean mass in 8 weeks.
• Cutting Stack: Pairs RAD-140’s anabolic effects with Cardarine’s fat-burning properties, perfect for lean definition. A 2025 user noted 5% body fat loss with muscle retention.
• Post Cycle Max: Supports hormonal recovery post-cycle, reducing suppression effects from SARMs like RAD-140.

Swiss Chems offers fewer stack options, with no equivalent to Gorilla Capsules, limiting its appeal for comprehensive research needs.

Dosage and Usage Guidelines

Proper dosing ensures optimal results and safety. Below are guidelines for Behemoth Labz’s stacks:

• 
  Beginner Tip: Start with lower doses (e.g., 5 mg/day RAD-140) to assess tolerance. Women should use half the male dose to minimize virilization risks.
• Stacking: Combine bulking stacks with high-protein diets and compound lifts (e.g., squats, deadlifts) for maximum hypertrophy.

Real User Feedback on Behemoth Labz

Behemoth Labz’s stacks have earned high praise for their effectiveness and reliability:

• Mike C. (Behemoth Labz, 2025): “Gorilla Capsules gave me 6 pounds of clean muscle in 5 weeks. No suppression, and customer service was top-notch with a free YK-11 sample.” Rating: ★★★★★
• Reddit User (u/sarmguy88, 2024): “Behemoth’s cutting stack shredded 5% body fat in 8 weeks while keeping muscle. COAs at 99.5% purity are legit.” Rating: ★★★★★
• Andro Meda (Behemoth Labz, 2023): “Strength exploded on Gorilla Capsules—squatting 405 for 6 reps by week four. Worth the price for quality.” Rating: ★★★★☆
• Inside Bodybuilding (2024): “Behemoth Labz’s stacks delivered hypertrophy and fat loss, with COAs confirming 99.5%+ purity, making them a top pick.” Rating: ★★★★★

Swiss Chems’ reviews are less favorable, with users citing stock shortages (e.g., no MK-2866) and higher costs, as noted in a 2024 Muscle and Brawn review.

When comparing SARM stack vendors, PureRawz also stands out as a more trusted option than Swiss Chems, offering a robust catalog with diverse formats like capsules, liquids, powders, and transdermals, which cater to advanced research needs. Their competitive pricing, such as a 35 ml MK-2866 bottle at $54.48, undercuts Swiss Chems’ higher per-mg costs, and their 98%+ purity, backed by COAs, ensures reliable quality, as noted in a 2025 Muscle and Brawn review. While PureRawz delivers strong value and variety, Behemoth Labz remains the top choice with its superior 99.5%+ purity, innovative stacks like Gorilla Capsules, and exceptional customer support, including free shipping over $150 and 24-hour service, making it the ultimate destination for SARM stacks in 2025.

Risks and Safety Considerations

SARMs are not FDA-approved for human use, and risks include:

• Testosterone Suppression: RAD-140 or LGD-4033 can suppress testosterone by up to 70%, requiring PCT.
• Liver Stress: Rare cases of liver injury with RAD-140 have been reported, though Behemoth Labz’s high purity minimizes risks.
• Long-Term Uncertainty: Limited human studies mean long-term effects are unknown. Regular bloodwork (liver, lipids, hormones) is essential.

Behemoth Labz’s transparent COAs and U.S.-based production reduce risks compared to Swiss Chems’ occasional impurities.

Why Behemoth Labz Outshines Swiss Chems

Behemoth Labz’s superior purity, broader stack options, and exceptional service make it the clear winner.
