NextChems is a research compound supplier operating at nextchems.com with a focused catalog of peptides, SARMs, and PCT compounds. They aren’t the largest vendor in the market by catalog size, and their US shipping window is longer than some competitors. 

But they can offer HPLC-tested products with a published quality guarantee, competitive pricing, strong international shipping, and a customs seizure policy that most vendors don’t bother to put in writing.

After Peptide Sciences, Science.bio, and Amino Asylum all exited the market between 2025 and early 2026, a lot of buyers are reassessing who they trust. NextChems has been a consistent presence in community discussions across that entire period. This isn’t because they have the flashiest catalog, but because they deliver what they say they will.

What is NextChems?

NextChems is a research chemical supplier that’s positioned itself deliberately at the intersection of quality and affordability. The company’s own description makes this clear: they negotiate bulk purchases directly from top peptide and research chemical manufacturers to pass wholesale pricing on to buyers, while investing the majority of resources into product research and development rather than marketing.

It doesn’t have the name recognition of SwissChems or the catalog breadth of a multi-category platform. However, it does have a tightly curated product list where each entry has been properly sourced and tested, pricing that consistently undercuts vendors with similar documentation standards, and an international shipping setup that puts it within reach of buyers outside the US who struggle to source from domestic-only vendors.

Products Sold by Next Chems

As of writing, the catalog is composed of:

• 11 SARMs
• 2 SARM-like Compounds
• 2 Peptides
• 5 PCT Compounds
• 1 Male Enhancement Supplement
• 22 other supplements (nootropics, fat loss, research, pharmaceutical)

The peptide catalog being limited to two products is the most significant caveat in this review. If you’re looking for Epitalon, Semax, Selank, GHK-Cu, or the broader longevity and cognitive peptide range, NextChems isn’t the place to source them. For core recovery and performance peptides (particularly BPC-157) it is one of the stronger value options currently operating.

Something worth mentioning is that all of their products come in capsule form, so there are no powder or liquid versions available. You can expect to pay between $39.95-$95.99 per product, with most costing around $60-$70 on average.

Testing Standards and Quality Guarantee

NextChems conducts HPLC testing on both raw powders and finished products. This dual-stage approach, consisting of verifying the incoming material and the finished compound, is a more thorough process than vendors who only test at one stage. It’s specifically highlighted on their BPC-157 product page as standard practice.

COAs are available through the company and reflect HPLC purity results. The products consistently document purity at 98% or above. To add to NextChems’ credibility, the Inside Bodybuilding review noted test results exceeding 100% in their reported figures (a testing artifact that indicates the sample is at or above the stated concentration). 

Independent community testing has corroborated solid purity results for SARMs compounds in particular.

The Quality Guarantee

NextChems backs their products with a full quality guarantee: if you purchase any product and send it to an HPLC-licensed testing facility, and the results come back negative, they will refund the full cost of the order including shipping charges. It’s one of the strongest quality guarantees in the market and applies across the catalog.

The guarantee matters because it puts real financial skin in the game. A vendor who offers a refund if independent testing fails is a vendor who believes their products will pass independent testing. Combined with the HPLC dual-stage testing process, it creates a quality assurance framework that holds up to scrutiny even if the brand doesn’t have the name recognition of larger vendors.

Pricing: Where NextChems Stands Out

Pricing is where NextChems earns the ‘best value’ framing. The company openly states that it keeps marketing spend low and passes savings from bulk purchasing to buyers, and the product prices reflect that approach.

BPC-157 at NextChems comes in capsule format, which is one of the more practical delivery formats for core peptide sourcing. Pricing is competitive against mid-tier vendors and meaningfully below the premium end of the market. 

For buyers who were sourcing BPC-157 from Peptide Sciences at mid-to-high pricing, NextChems represents a meaningful cost reduction for the same fundamental compound with a similar quality guarantee backing it.

The discount structure adds further value:

• BRAWN20 for 20% off. Use this code at checkout for the best available price
• 10% off when purchasing 3 or more products simultaneously
• Free US shipping on orders over $100
• Free international shipping on orders over $300

The one pricing caveat worth noting is that NextChems does not offer a cryptocurrency discount. Vendors like SwissChems offer 20% off for Bitcoin payment, which can make them more competitive for buyers comfortable with crypto. If you’re paying by card, NextChems’ baseline pricing holds up well against the comparison.

Next Chems Shipping

Next Chems offers both domestic and international shipping. Domestic shipping takes around 7 business days, whereas international shipping takes two weeks. Next Chems even offers free shipping for domestic orders $100+ and international orders $300+.

Shipping: Strong for International Buyers, Slower Domestically

NextChems ships to a wide range of countries, explicitly covering the US, Canada, Europe, South Asia (including India, Pakistan, and Bangladesh), and the Middle East. That international reach is a genuine differentiator. Many established vendors either don’t ship internationally or have significant delivery unreliability outside the US.

The trade-off for US buyers is delivery speed. Domestic US shipping takes approximately 7 business days, which unfortunately is longer than the 2–4 day windows offered by US-based vendors. It’s  best to plan purchases ahead because the pricing advantage typically justifies the extra few days.

Customs seizure policy: If an international package is confiscated by customs, NextChems offers a 30% discount on a subsequent order. This won’t cover the cost of a seized shipment, but it’s a concrete policy commitment that most vendors don’t put in writing. Know your country’s import regulations before ordering.

Tracking: All orders ship with a tracking number. Packages are dispatched to USPS every two days.

Cancellation window: One hour from order placement. After that, cancellations are not guaranteed. Once endorsed for shipping, orders cannot be modified.

Who NextChems Is Best For

NextChems has a clearly defined buyer. Understanding whether that’s you is more useful than a generic recommendation.

Best fit: 

• International buyers who need reliable global shipping with a documented customs policy.
• Value-conscious buyers who prioritize pricing without sacrificing quality documentation. 
• Buyers whose primary needs are core staple peptides — particularly BPC-157 — alongside SARMs, where NextChems has a strong and comprehensive catalog. 
• Buyers who want a full quality guarantee without paying the premium tier pricing that usually accompanies one.

Consider alternatives if: 

• You need the full range of peptide categories (longevity compounds, bioregulators, cognitive peptides, tanning peptides) that a broader catalog vendor like SwissChems carries. 
• You need faster US domestic delivery. 
• You’re specifically looking for nootropic compounds alongside your peptide sourcing.

My Experience with Next Chems

We’re always on the hunt to discover the best new research chemical companies out there. So, we thought it would be helpful to our readers if I placed an order with Next Chems and reviewed their products up close.

Here’s a look at the ordering process along with an unboxing video of my package. I’ve also included info on what you need to know about these research chemicals and how they’re applied in the biohacking industry.

Selecting Products

To check out what Next Chems had to offer, I simply went to the tab “Shop”. Then, I browsed their selection of SARMs and PCT products. Here are the products I decided to order:

S4 (Andarine)

Tamoxifen (Nolvadex)

Check Out

Once I added both of the above products to my cart, I reviewed my order before proceeding to checkout. Everything looked good, so I hit the checkout button.

Payment Methods

I chose to use a credit card (gotta earn those points, right?). Something different about Next Chems from most research chemical companies is that it offers a more secure form of payment.

I was required to create a Max Redemption account in order to use my credit card. The process only took a few minutes to complete, but keep in mind there is a convenience charge for using the service.

Shipping and Delivery

I received my package about one week after placing my order. Here’s my unboxing experience:

About the Products I Received

I decided to order one SARM and one PCT product. Here’s a closer look at S4 and Tamoxifen!

S4 (Andarine)

Andarine is a selective androgen receptor modulator (SARM) that was originally developed to prevent muscle breakdown as well as promote prostate health. Basically, it mimics the function of testosterone in the body without the side effects associated with anabolics.

One study showed that S4 restored skeletal muscle strength, body composition, and bone mineral density in castrated male rats. Male rats were treated with S4 (3 or 10 mg/kg), dihydrotestosterone (DHT) (3 mg/kg), or vehicle for 8 wk.

Those that were given S4 displayed restored soleus muscle mass and strength and levator ani muscle mass to that seen in intact animals, caused a significantly larger increase in total body bone mineral density than DHT, and also demonstrated agonist activity in the pituitary and significantly decreased plasma LH and FSH levels in castrated animals in a dose-dependent manner. (1)

Another study investigated the bone and body composition effects of S4 in an ovariectomy-induced model of accelerated bone loss. The study examined 120 female Sprague-Dawley rats that were randomly assigned to twelve treatment groups. The S4-only treatments included S4 administered at 0.1, 0.3, 0.5, 0.75, 1.0, and 3.0 mg/day. Other treatments included DHT, vehicle, or S4 mixed with Bicalutamide.

It was discovered that the mice treated with S4 maintained whole body and trabecular BMD, cortical content, and increased bone strength while decreasing body fat. (2) The data collected from both studies show that S4 could potentially be used for fracture reduction in human patients.

While there are limited studies conducted on human consumption and use of Andarine, some researchers suggest that human equivalent dosages would equate to an average of 50 mg per day, intended to be taken for 8-12 weeks.

Tamoxifen (Nolvadex)

Tamoxifen, also referred to as Nolvadex, is a selective estrogen receptor modulator that serves as an antineoplastic and antiestrogen agent. It was originally developed to treat breast cancer in women (3), but has recently been used for inducing ovulation in women (4) and treating gynecomastia (5)(6) and infertility (7)(8)(9) in men.

The majority of studies involving male subjects with subfertility/infertility or gynecomastia have utilized dosages of 10-20 mg per day for a period of 6-12 weeks. However, some studies adminster treatment for up to 6 months.

Nolvadex is commonly used by male bodybuilders and athletes as part of their PCT regimen, and is considered to be more powerful than Clomid.Most biohacking communities state that men typically use Nolvadex for 4 weeks total, taking 40 mg per day the first week, 20 mg per day for the next 2 weeks, and then 10 mg per day the last week.

Next Chems vs. Other Top Research Chemical Companies

Want to see how Next Chems compares to its competition? Let’s quickly compare them side-by-side to 3 of the best research chemical companies out there.

Next Chems vs. Swisschems

SwissChems is one of the most established research compound vendors currently operating, with a catalog that spans SARMs, peptides, nootropics, PCT compounds, and bioregulators across 122+ products. SARMs are available in capsule, liquid, and powder formats, with pricing typically ranging from $40–$90 depending on compound and format. The 20% Bitcoin discount brings costs down significantly for buyers comfortable with crypto, and free US shipping kicks in above $100.

NextChems is preferable to SwissChems if you want the best value for money without sacrificing documentation quality. Pricing sits in the budget-to-mid range and the quality guarantee is hard to beat — if independent HPLC testing on any product comes back negative, NextChems will refund the full order including shipping. The SARMs catalog covers 16 compounds including injectable and sublingual formats you won’t find at most vendors, and free international shipping above $300 makes it the stronger option for non-US buyers.

SwissChems is the better choice if you want a broader catalog under one roof — particularly if you’re sourcing peptides, nootropics, or bioregulators alongside your SARMs, or if paying with Bitcoin to take advantage of the 20% discount.

Next Chems vs. Alpha Star Labs

Alpha Star Labs is another newcomer in the research chemical industry but has been around for a few more years than Next Chems. They offer both liquid and powder forms of several of today’s most popular SARMs and research chemicals.

Products range from $45-$90 per 30 mL vial or 1 g packet. Solutions typically range from $50-$70, whereas powder forms of research chemicals range from $45-$90.

Alpha Star Labs is the better choice of the two if you want to have the option of liquid or powder SARMs. Next Chems, however, is best if you want a wide range of research chemicals in addition to SARMs like male enhancement pills, PCT, or anti-aging and fat-loss agents.

Next Chems vs. Chemyo

Chemyo is one of the leading suppliers of high-quality SARMs available today. They offer a huge range of liquid and powder forms of SARMs, and they even sell nootropics and other supplements too. Prices range from $60-$80 per 50 ml solution, and $15-$100 per 1 g of powder.

Typically, you get the most bang for your buck with solution-based SARMs if you go with Alpha Star Labs over other companies since they sell 50 ml size solutions and not the typical 30 ml size. They even offer value packs for additional discounts too.

Next Chems is preferable to Chemyo if you want powder SARMs instead, or want more options for other research chemicals.

Final Thoughts

Next Chems definitely impressed me with its selection of research chemicals, level of product testing, pricing, security for payments, and overall product design. I appreciate the extent in which Next Chem goes to separate themselves from their competition and thought it was cool that they color code each of their capsules based on what product it is.

While their shipping may take just a bit longer than other brands, their products are certainly worth the slightly extra wait. While they don’t offer research chemicals in powder or liquid form, I still think they’re a great option for most researchers who prioritize ease of use.
