A lookup provider constructed on precision and trust
For over eight years, SwissChems has furnished one of the biggest research-compound catalogs accessible somewhere — backed by means of unbiased trying out and a purity popular we refuse to compromise.

Earning believe via transparency
At SwissChems, we see ourselves as greater than a supplier. Our mission is to furnish research-grade compounds with whole transparency, so the human beings who remember on our merchandise usually recognize precisely what they are working with.

Innovation, integrity, and accessibility information each and every choice we make. They are the motive researchers proceed to pick out us — order after order.

Our Philosophy
Quality is not a characteristic right here — it is the complete cause we exist.

Quality is the complete point
We do not reduce corners on quality, due to the fact best is the whole cause we exist. Every compound we provide undergoes impartial third-party HPLC checking out and is demonstrated to a purity fashionable of 99% or higher. We submit lab reviews so researchers can verify exactly what they are receiving — batch by way of batch.

We would as a substitute let the exceptional of our compounds talk for itself than lean on advertising and marketing claims. That center of attention on substance over noise has described SwissChems from the beginning, and it is not changing.

Lab Testing, Purity & Variance

Do you take a look at your products?
Yes. Batches are submitted for unbiased evaluation by way of approved third-party laboratories, basically Janoshik Analytical. Testing makes use of mounted laboratory methods, most frequently High-Performance Liquid Chromatography (HPLC), with extra techniques the place a compound requires them.

Lab reviews are made on hand so you can affirm the cloth you received. Reports are lot-specific. Always test that the lot range on your product fits the record you are reading

How shut to the label must the quantity be?
Our preferred is inside 10% both facet of the labeled amount.

A small distinction between the labeled quantity and the examined quantity is ordinary and expected. As lengthy as the end result falls inside that 10% margin, the batch meets our specification.

If a end result falls backyard it — whether or not underneath or over — the batch is out of specification. It is held and reviewed earlier than any selection to launch it.

Is purity said the identical way for peptides?
No. Lyophilized (freeze-dried) peptides are said as an specific purity discern instead than a band, reflecting the one-of-a-kind analytical strategy used for peptide material.

For blends — merchandise the place greater than one lively compound is blended — a single purity proportion is now not meaningful, due to the fact the determine would describe the combination instead than any one compound in it. Blends are assessed on identification and on the content material of every issue instead.

The purity grade that applies to a given product is mentioned on that product’s lab report.

What do the lab reviews certainly measure?
Two separate things, which reply two special questions:

Purity — of the fabric in the container, how an awful lot of it is the compound itself, and how a lot is something else.

Content — how a lot of the compound is certainly there, in contrast with the quantity printed on the label.

A batch has to bypass on both. A product can be very pure however barely underneath the labeled amount, or precisely the labeled quantity however much less pure — which is why each figures show up on the report.

Where does that 10% parent come from?
It comes from the United States Pharmacopeia (USP), the company that units posted first-rate requirements for drug treatments in the US. Two of its chapters set the identical ±10% expectation — a vary of 90% to 110% of the labeled amount:

USP Chapter <905>, on dose uniformity, offers 90–110% of the labeled quantity as the everyday acceptance range.

USP Chapter <795>, on compounded preparations, offers ±10% of labeled electricity for components that have no legit widespread 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 with the aid of the Internet. JAMA. 2017;318(20):2004–2010.

Research compounds have no posted USP wellknown precise to them. We have chosen to practice this pharmaceutical-grade vary to our very own merchandise anyway. To be clear about what that means: it is a general we keep ourselves to voluntarily, no longer one imposed on this category. We use it due to the fact it is the most rigorous published benchmark available, and due to the fact a popular you can appear up your self is well worth extra than one we invented.

Both chapters are publicly viewable — hyperlinks are at the give up of this document.

Why do drugs range extra than uncooked powder?
Capsules comprise very small quantities of lively compound blended into a filler. When you divide a small volume of powder throughout heaps of capsules, character drugs land barely above or barely under the common — the equal way man or woman scoops from a bag by no means weigh exactly the same. Bulk powder, weighed in one quantity, does now not have that issue.

This is expected, and the posted requirements enable for it. USP <905> acknowledges that an character tablet may additionally sit down similarly from the labeled quantity — normally in the area of 85% to 115% — whilst the batch as a entire is nevertheless held to the 90–110% range.

The popular the batch have to meet does now not widen. Only the predicted variant between one tablet and the next is wider.

Why do some certificates exhibit “98%+” rather of an precise number?
It relies upon on which laboratory issued the report, and how that lab reviews high-purity material.

Where a record is banded, purity is given as a vary alternatively than a single number:

96%+ — the pattern examined someplace between 96% and 98%.
98%+ — the pattern examined someplace between 98% and 100%.
Under that format, 98%+ is the pinnacle band the widespread evaluation issues; there is no greater band on that scale. So a 98%+ end result is no longer cloth that barely scraped previous a threshold — it is the best grade the structure reports, and the genuine purity sits someplace between 98% and 100%. Narrowing it to an specific decimal takes extra instrument time and price except telling you something you can act on. Within that format, the band is the significant figure.

Where a document suggests an actual proportion alternatively — for instance 99.4% — that displays the technique and reporting style of the laboratory that issued it, no longer a specific category of material. We work with greater than one approved laboratory, which includes ISO-accredited partners, so each codecs show up throughout our catalog. Read every certificates in opposition to the lot variety on your product.

Why does posted lab facts be counted in this category?
Mislabeling in the on-line research-compound market is nicely documented. A 2017 find out about posted in the Journal of the American Medical Association analyzed forty four merchandise bought on line as SARMs. Only 52% contained a SARM at all, and the quantity cited on the label matched the quantity definitely current in fewer than 1/2 of the merchandise tested.

Our response is to submit laboratory reviews as they are issued, which include consequences that come in under a hundred percent of the labeled amount. Reported figures describe the examined batch at the time of analysis.

Why isn’t the end result precisely 100%?
Because actual measurements not often are. Every bodily step — synthesis, drying, weighing, blending, filling — introduces small variation, and the take a look at instrument itself has a margin of accuracy. A end result a few percentage above or beneath the label, sitting inner the acceptance range, is what authentic lab statistics appears like.

We post effects as the laboratory problems them, barring adjustment.
