Who we are
A research and pharmaceutical supplier that shows its work
RRK Labs supplies research-grade peptides, bacteriostatic water and pharmaceuticals to laboratories, universities, and independent researchers. We built the company around a simple idea: if you cannot verify what is in the vial, it has no place in a study. So every compound we stock is sourced for purity, tested by an independent laboratory, and documented with a certificate of analysis you can read before you buy. Our pharmaceutical catalogue is handled the same way — quoted by hand, sourced from a named warehouse, with a lead time we tell you up front.
- Sourced for purityResearch-grade compounds, lyophilized and sealed in glass vials.
- Documented by lotA certificate of analysis is recorded against every batch number.
- Discreet and fastPlain, unbranded packaging, dispatched the next business day.
- Three warehousesStocked in the US, with pharmaceutical fulfilment from India and Russia.
The process
From synthesis to your bench
Stocked products and pharmaceutical requests both follow a documented path, so you always know what you are getting and when it will arrive.
01
Sourced to spec
Compounds are produced to a research-grade specification and sealed in glass vials.
02
Independently tested
Each batch is analysed by an independent laboratory using HPLC and mass spectrometry.
03
COA published
The certificate of analysis is recorded against the lot number and available before you buy.
04
Ordered and dispatched
Order stocked items online, or email us for pharmaceuticals and bulk kits. We pack discreetly and dispatch the next business day.
Answers
Common questions
Compliance, testing, storage, and shipping, in plain language.
Read the full FAQWhat does "for research use only" mean?
Our products are sold strictly for in-vitro laboratory research. They are not drugs, supplements, or food, and are not intended for human or veterinary use.
How do you test your peptides?
Every batch is analysed by an independent laboratory using HPLC to measure purity and mass spectrometry to confirm identity. The report is published against the lot number.
Do you provide a certificate of analysis?
Yes. Each product links to the certificate of analysis for its current batch, so you can confirm identity and purity before you order.
Do you supply more than peptides?
Yes. Alongside research peptides and bacteriostatic water, we keep a separate pharmaceutical catalogue that is not listed in the online shop. Email us or open our Telegram channel for the full list, availability and pricing. Those orders ship from our India warehouse in about two weeks, or Russia in about four.
Can I order in bulk?
Yes. Bulk peptides are sold as 10-vial kits at a lower per-vial price, shipped from our US warehouse in 7–10 days. Send us the compounds and quantities and we will reply with pricing and a lead time.
How fast is shipping?
Orders are dispatched the next business day and sent in plain, unbranded packaging. Delivery time then depends on the service selected at checkout.
How should peptides be stored?
Lyophilized peptides are best kept cool and dark. Once reconstituted with bacteriostatic water, store refrigerated and use within the documented window.
