FAQs

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.

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.

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.
