Our verdict: SwissChems is our current pick for SARMs, PCT compounds and peptides. It publishes lot-specific third-party lab reports, has a written quality-claim process, carries a large range and takes cards, bank transfers and crypto. The weak points are international customs risk, US-only card payments and the usual research-only limits. Everything below was checked on its own public pages on 30 October 2026.
SwissChems at a glance
| What we found | |
|---|---|
| Company | Founded in 2018 and based in the US, according to its who we are page. |
| Range | The shop lists SARMs, PCT compounds (tamoxifen, clomiphene, enclomiphene, raloxifene, anastrozole, letrozole), around 50 peptides, about 30 nootropics and bioregulators in one catalog. SARMs are sold as 60-capsule bottles. |
| Lab reports | SwissChems publishes lot-specific certificates of analysis on its independent test results page (131 reports were listed when we checked on 30 October 2026). Each report names the product, the lot and the lab. The report we opened, for GW-501516 (cardarine) lot J26CYG, was issued by Freedom Diagnostics Testing on 3 October 2026 and shows identity confirmed by LC-MS and 99.79% purity by HPLC. |
| Testing standard | SwissChems’ FAQ says batches go to accredited third-party labs, “principally Janoshik Analytical”, and that it works with more than one lab; the reports we opened were from Freedom Diagnostics Testing. It also states its own standard: the measured amount must be within 10% of the label. |
| Quality claims | Its quality assurance page sets out a written claim process: if your own third-party lab test (with chromatograms and the lot number) shows a problem within 30 days of delivery, SwissChems says it will review it and, if confirmed, replace the product or credit it and pay up to $100 of the testing fee. |
| Bottle check | Bottles carry a scratch-off code that you can check on its product verification page. |
| Shipping | USPS in the US (3–5 business days) and internationally (about 2–3 weeks), FedEx express for eligible US addresses; free shipping from $100 in the US and $300 internationally, per its shipping page. Details below. |
| Payment | US-issued Visa and Mastercard, bank and wallet transfers, and seven cryptocurrencies; no PayPal. Details below. |
| Support | Email, phone and live chat; SwissChems says support is available 24/7. Details below. |
Product selection
SwissChems carries the SARMs most people search for, all as capsules: RAD-140, LGD-4033, ostarine, S-23, S4, YK-11, RAD-150 and AC-262, plus MK-677 and cardarine. It does not sell SR9009 (stenabolic); it sells SR-9011, a related but different compound. Earlier versions of this review said Ligandrol was missing; it is now in stock.
For PCT it lists tamoxifen, clomiphene, enclomiphene and raloxifene, and the aromatase inhibitors anastrozole and letrozole. The peptide range covers BPC-157, TB-500 (and a BPC-157 + TB-500 blend), ipamorelin, CJC-1295, sermorelin, tesamorelin, IGF-1 LR3, MOTS-c and GHK-Cu, among others. There are also value packs that combine SARMs.
Pricing
SwissChems is not the cheapest shop. On 30 October 2026, its 60-capsule SARM bottles ranged from about $64 (ostarine) to $90 (RAD-140), with free US shipping from $100 and free international shipping from $300. The product boxes on this page show the latest price we fetched. Given what lot-by-lot testing costs, we would rather pay that than gamble on a much cheaper bottle.
Quality control
This is the main reason it is our pick. The test results page lists reports by product and date, and each report names the lot. We opened the report for GW-501516 lot J26CYG: issued by Freedom Diagnostics Testing (received 2 October, reported 3 October 2026), identity confirmed by LC-MS, purity 99.79% by HPLC, with the chromatogram and mass spectrum attached.
The FAQ is unusually detailed. It explains the difference between purity and content, why capsules vary more than powder, and why some certificates show a band (“98%+”) instead of an exact number. It also says SwissChems publishes results as the lab issues them, including results below 100% of the label, and holds itself to a ±10% content standard taken from US Pharmacopeia chapters, voluntarily.
What to do with that: match the lot on your bottle to a report, and check the lab name and date. If something looks wrong, its quality-claim process asks for your own third-party report within 30 days of delivery.
Shipping
US orders go by USPS (3–5 business days flat rate, 5–7 on free shipping) or FedEx Overnight / 2-Day for eligible addresses; orders paid before 12 PM EST on business days ship the same day, according to its FAQ. International orders go by USPS and take about 2–3 weeks (1–2 to Canada). Orders mixing peptides with capsules can arrive as two parcels. Tracking is emailed after dispatch.
Payment
According to its payments page, SwissChems takes Visa and Mastercard for US-issued cards, bank and wallet transfers (Plaid ACH, Zelle, Interac, Coinbase) and seven cryptocurrencies (BTC, ETH, BCH, SOL, ZEC, TRX, DOGE). PayPal is not offered. Card charges show a payment processor’s name on your statement, not “SwissChems”.
What we would like SwissChems to do better
- Customs. For international orders, SwissChems states that it does not reship or refund packages seized by customs; it offers 30% off a future order instead. Check your own country’s import rules before ordering.
- More than one lab. The FAQ names Janoshik Analytical as its main lab, while the reports we opened were from Freedom Diagnostics Testing. Both appear, so read the lab name on the report that matches your lot.
- Card payments are US-only, and the statement shows a processor’s name, which can confuse people.
- Returns are limited to unopened products within 7 business days, with fees, per its FAQ.
- Research-only. Like every seller in this market, SwissChems labels its products for laboratory research only, not for human consumption, and asks buyers to confirm they are 21 or older at checkout. There is no dosing or safety guidance, which is correct for a research supplier but means you should read independent evidence first: our SARMs database is a good place to start.
Customer reviews online
We don’t publish customer testimonials, and reviews on forums such as Reddit are anecdotal: they can’t tell you what was in a bottle. When we first reviewed SwissChems, most of the reviews we found online were positive, and the most common complaint was delivery time, which depends largely on couriers and customs once a parcel has shipped. For something you can check, match the lot on your bottle to a published lab report (see quality control above).
Customer support
Support is by email (support@swisschems.is) and phone (+1 870 533 5581); SwissChems says it answers around the clock. Its pages also list a live chat.
Conclusion
No shop in this market is beyond criticism. Today SwissChems does the things we care most about: lab reports you can match to your bottle, written policies and no health claims. That is why it is our current pick, and why our partner links go to it (see our affiliate disclosure). We will keep checking; if that changes, this review will say so.
