Lab Testing, Purity & Variance
Yes. Batches are submitted for independent analysis by accredited third-party laboratories, principally Janoshik Analytical. Testing uses established laboratory methods, most commonly High-Performance Liquid Chromatography (HPLC), with additional methods where a compound requires them.
Lab reports are made available so you can verify the material you received. Reports are lot-specific. Always check that the lot number on your product matches the report you are reading
Our standard is within 10% either side of the labeled amount.
A small difference between the labeled amount and the tested amount is normal and expected. As long as the result falls within that 10% margin, the batch meets our specification.
If a result falls outside it — whether under or over — the batch is out of specification. It is held and reviewed before any decision to release it.
No. Lyophilized (freeze-dried) peptides are reported as an exact purity figure rather than a band, reflecting the different analytical approach used for peptide material.
For blends — products where more than one active compound is combined — a single purity percentage is not meaningful, because the figure would describe the mixture rather than any one compound in it. Blends are assessed on identity and on the content of each component instead.
The purity grade that applies to a given product is stated on that product’s lab report.
Two separate things, which answer two different questions:
Purity — of the material in the container, how much of it is the compound itself, and how much is anything else.
Content — how much of the compound is actually there, compared with the amount printed on the label.
A batch has to pass on both. A product can be very pure but slightly under the labeled amount, or exactly the labeled amount but less pure — which is why both figures appear on the report.
It comes from the United States Pharmacopeia (USP), the organization that sets published quality standards for medicines in the US. Two of its chapters set the same ±10% expectation — a range of 90% to 110% of the labeled amount:
USP Chapter <905>, on dose uniformity, gives 90–110% of the labeled amount as the normal acceptance range.
USP Chapter <795>, on compounded preparations, gives ±10% of labeled strength for substances that have no official standard of their own.
Van Wagoner RM, Eichner A, Bhasin S, Deuster PA, Eichner D. Chemical Composition and Labeling of Substances Marketed as Selective Androgen Receptor Modulators and Sold via the Internet. JAMA. 2017;318(20):2004–2010.
Research compounds have no published USP standard specific to them. We have chosen to apply this pharmaceutical-grade range to our own products anyway. To be clear about what that means: it is a standard we hold ourselves to voluntarily, not one imposed on this category. We use it because it is the most rigorous published benchmark available, and because a standard you can look up yourself is worth more than one we invented.
Both chapters are publicly viewable — links are at the end of this document.
Capsules contain very small amounts of active compound mixed into a filler. When you divide a small quantity of powder across thousands of capsules, individual capsules land slightly above or slightly below the average — the same way individual scoops from a bag never weigh precisely the same. Bulk powder, weighed in one quantity, does not have that issue.
This is expected, and the published standards allow for it. USP <905> recognizes that an individual capsule may sit further from the labeled amount — generally in the region of 85% to 115% — while the batch as a whole is still held to the 90–110% range.
The standard the batch must meet does not widen. Only the expected variation between one capsule and the next is wider.
It depends on which laboratory issued the report, and how that lab reports high-purity material.
Where a report is banded, purity is given as a range rather than a single number:
- 96%+ — the sample tested somewhere between 96% and 98%.
- 98%+ — the sample tested somewhere between 98% and 100%.
Under that format, 98%+ is the top band the standard analysis issues; there is no higher band on that scale. So a 98%+ result is not material that barely scraped past a threshold — it is the highest grade the format reports, and the actual purity sits somewhere between 98% and 100%. Narrowing it to an exact decimal takes more instrument time and cost without telling you anything you can act on. Within that format, the band is the meaningful figure.
Where a report shows an exact percentage instead — for example 99.4% — that reflects the method and reporting style of the laboratory that issued it, not a different class of material. We work with more than one accredited laboratory, including ISO-accredited partners, so both formats appear across our catalog. Read each certificate against the lot number on your product.
Mislabeling in the online research-compound market is well documented. A 2017 study published in the Journal of the American Medical Association analyzed 44 products sold online as SARMs. Only 52% contained a SARM at all, and the amount stated on the label matched the amount actually present in fewer than half of the products tested.
Our response is to publish laboratory reports as they are issued, including results that come in below 100% of the labeled amount. Reported figures describe the tested batch at the time of analysis.
Because real measurements rarely are. Every physical step — synthesis, drying, weighing, blending, filling — introduces small variation, and the test instrument itself has a margin of accuracy. A result a few percent above or below the label, sitting inside the acceptance range, is what genuine lab data looks like.
We publish results as the laboratory issues them, without adjustment.

Peptides
SwissChems research peptides are supplied in lyophilized (freeze-dried) powder form. Lyophilization is standard for research-grade peptide compounds as it maximises stability and shelf life during transit and storage.
Bacteriostatic water for reconstitution is not included and must be sourced separately.
Lyophilized peptides are stable at room temperature for several days to weeks in original sealed packaging. For extended laboratory storage, 4°C (refrigerated) is recommended; long-term archival storage should use −20°C (frozen). Peptide vials must be shielded from light at all stages.
When transferring vials from frozen storage, allow equilibration to room temperature prior to opening to prevent atmospheric moisture condensation — peptides are hygroscopic and moisture uptake can compromise integrity. For multi-use experimental protocols, aliquoting minimises repeated freeze-thaw cycles.
Lyophilized SwissChems peptides carry a shelf life of up to 24 months from the manufacture date when stored correctly: sealed, shielded from light, and held at −20°C (frozen) for long-term archival, or at 4°C (refrigerated) for active laboratory use.
Shelf life reduces substantially once a vial has been opened and reconstituted. The manufacture date and lot number are traceable via the COA documentation .
SARMs, nootropics, and PCT compounds in capsule or powder form carry a shelf life of up to 24 months from manufacture date when stored sealed, away from direct light, at controlled room temperature (15–25°C).
Liquid solutions should be stored at 4°C and used within 6 months of opening. SwissChems assumes no liability for degradation resulting from improper storage post-delivery.
SwissChems peptide vials are identified by stopper colour, as specified on each product page. Vials sold individually are unlabelled; identification relies on stopper colour only.
In rare instances where standard stopper colours are unavailable, an alternative colour is used — the SwissChems support team can confirm identification if required.
All SwissChems liquid and solution products contain 7% ethanol. This is consistent across the liquid formulation range.
Peptide kits and individual peptide vials are dispatched as separate consignments with separate tracking numbers — two tracking emails are issued. If only one tracking number has been received, check spam and junk folders or request confirmation from support@swisschems.is.
Peptide kits are also packed in a dedicated customs-clearance box. Any text on the outer box is specific to the customs process and does not describe the contents of the vials — disregard it. Vial identification is confirmed by stopper colour.

Product Quality
All SwissChems products are sold strictly as research chemicals for laboratory and research use. They are not for human or animal consumption, and we cannot discuss, advise on, or respond to inquiries regarding use, dosing, administration, or outcomes of any kind.Support is limited to analytical and order matters. This includes certificates of analysis, lot identification, specification and testing questions, shipping, and order issues.Product complaints are assessed against analytical specification only. If you believe a product is outside specification, contact us with your order and lot number.
SwissChems compounds are sold for research purposes only, in accordance with applicable regulations and as defined in the SwissChems Terms and Conditions. Customers are responsible for confirming the legal status of specific compounds in their jurisdiction prior to purchase.
SwissChems does not provide usage or dosage guidance, as doing so would be inconsistent with the research-only designation of these compounds.
Every SwissChems batch undergoes independent third-party purity testing at a USA-based laboratory prior to distribution. Test results are published periodically on the Independent Test Results page. Certificates of Analysis (COA) are available for reference at the product level.
A SwissChems COA documents the independently verified purity of a specific compound batch, confirmed via HPLC (High Performance Liquid Chromatography) analysis at a USA-based third-party laboratory. Each COA specifies the compound name, batch identifier, purity percentage, analytical method used, and the issuing laboratory.
SwissChems does not self-certify; all COA documentation is produced by laboratories with no commercial relationship to SwissChems. COAs are published at Independent Test Result Page
SwissChems quality testing extends beyond HPLC purity analysis. Each batch undergoes testing for heavy metal content and residual solvent levels as part of the standard pre-distribution quality protocol at a USA-based independent laboratory.
This multi-panel approach confirms that compounds meet research-grade specifications across purity, elemental safety, and solvent residue thresholds. Full documentation is published at Independent Test Result page.
SwissChems guarantees the purity of all compounds. If independent HPLC testing at a licensed facility returns a result inconsistent with stated purity, SwissChems will refund: (1) the cost of the HPLC test, and (2) the full order amount including shipping.
