There is no working Science.bio discount code, because Science.bio has closed. Its website now says it “has made the decision to permanently close and discontinue the sale of research products” (checked 30 October 2026), and archived copies show a closure notice by February 2026. Science.bio also warns that any website claiming to be Science.bio, or its successor, is fraudulent. Here is what that means if you used to buy there.
Is Science.bio still open?
No. The Science.bio homepage is now a closure notice. It thanks customers and adds that “any website, entity, or individuals claiming to be Science.bio, a successor to Science.bio, or falsely claiming to sell our products are fraudulent, unauthorized, and have absolutely no affiliation with our company.”
Do old Science.bio coupon codes still work?
No. With the shop closed, no Science.bio code works anywhere. Be careful with sites that use the Science.bio name and offer a code: by Science.bio’s own statement, they are not Science.bio.
What Science.bio was known for
Science.bio (previously known as irc.bio) was one of the best-known US research-chemical shops, selling SARMs, nootropics, peptides and related compounds. Our earlier reviews praised its range and testing. Its closure is part of a wider shake-out: Peptide Sciences has also shut down (see Peptide Sciences alternatives), and the FDA has kept sending warning letters to online SARMs sellers, including one in December 2025 that named ostarine, MK-677, cardarine and LGD-4033 as unapproved new drugs.
Where to buy instead
Our current pick
If you used Science.bio for SARMs, PCT compounds, peptides or nootropics, our current pick is SwissChems. What we checked on its own pages:
- Lot-specific 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.
- A written quality claim process. 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.
- Range. The shop lists SARMs, PCT compounds (tamoxifen, clomiphene, enclomiphene, raloxifene, anastrozole, letrozole), around 50 peptides, about 30 nootropics and bioregulators in one catalog.
- Shipping and payment. US orders ship by USPS or FedEx; international orders by USPS. It takes US Visa and Mastercard, bank transfers (ACH, Zelle, Interac) and crypto. No PayPal.
More detail, including what we would like SwissChems to do better, is in our SwissChems review. You can also visit SwissChems directly.
