⚠️ Important Notice: Science.bio has permanently closed as of January 27, 2026. The website now displays a closure notice confirming all sales of research products have been discontinued. All outstanding orders at the time of closure were either fulfilled or fully refunded. This article is preserved as a historical reference for researchers who used the platform.
Science.bio Has Permanently Closed
Science.bio announced its permanent closure, stating: “It is with a heavy heart that we announce Science.bio will be permanently closing. All outstanding orders will be either fulfilled or fully refunded.”
The company’s official statement confirmed that after careful consideration, Science.bio made the decision to permanently close and discontinue the sale of all research products, expressing gratitude for customer support over the years.
This marks the end of a company that had one of the most turbulent histories in the research chemical space: shutting down once in February 2022, relaunching in May 2023, and now closing permanently in early 2026.
Why Did Science.bio Close?
The closure was not triggered by a specific enforcement action. It was a business decision made in response to a convergence of pressures that also led other major vendors to shut down around the same time.
These included:
- escalating FDA enforcement activity, including over 50 warning letters in September 2025 and physical raids on competitors;
- criminal prosecutions of other vendors;
- payment processing restrictions as credit card companies categorized research compound sales as high-risk or prohibited, pharmaceutical litigation; and
- proposed federal legislation signaling congressional intent to eliminate the research-use-only framework for FDA-approved drug analogs.
Science.bio in Context: A Market-Wide Shakeout
Science.bio’s closure was not an isolated event. The research peptide industry lost more vendors between mid-2025 and early 2026 than in the previous five years combined. FDA raids, criminal prosecutions, pharmaceutical lawsuits, and voluntary closures swept through the market. At least eight major vendors closed during this period, including Peptide Sciences, Amino Asylum, Paradigm Peptides, Science.bio, Royal Research, Peptide Tech Labs, American Research Labs, and Unchained Compounds.
Three forces converged simultaneously: FDA enforcement escalated from warning letters to warehouse raids and criminal prosecutions, Eli Lilly and Novo Nordisk filed lawsuits against GLP-1 suppliers, and quality testing failures at major vendors destroyed reputations.
Science.bio’s Legacy
Despite the closure, Science.bio had a generally positive reputation in research communities for its core products. The closure was business-driven, not quality-driven.
Science.bio was one of the most respected research chemical suppliers, known for quality and testing. Notably, its customer handling at closure was better than most because the company committed to fulfilling all outstanding orders or providing full refunds before shutting down.
Who Was Science.bio?
Science.bio, originally known as IRC.bio before federal regulations forced its first closure in November 2018. relaunched in April 2019 and became one of the most trusted names in the research compound space. The company offered over 200 products including SARMs, nootropics, peptides, metabolics, and longevity compounds, serving clients ranging from individual lab technicians to larger research institutions.
The company was especially well known for:
Quality Control: Strict batch and lot tracking, third-party testing via HPLC, NMR spectroscopy, TLC, ICP-MS, GC-MS, and other methods, with full lab reports publicly available for every product.
Product Range: SARMs including Ostarine MK-2866, Testolone RAD-140, Ligandrol LGD-4033, Andarine S4, and YK-11, alongside a broad nootropic and peptide catalog.
Transparency: All compounds were manufactured in ISO-compliant facilities, with products traceable by lot number to third-party certificates of analysis.
Shipping: Free 2–3 day FedEx domestic shipping, with signature confirmation on orders over $200 and reshipping guarantees for customs issues.
The company held a Trustpilot rating of 4.5 stars, with over 87% of reviewers rating their experience as excellent.
Our Past Experience With Science.bio






Our team at Muscle and Brawn previously tested CoQ10 powder and Ostarine MK-2866 from Science.bio, and both products met or exceeded expectations for purity, solubility, and organoleptic properties. The ordering process was smooth, payment via credit card worked as described, and delivery arrived within the stated timeframe.
Science.bio represented a high standard for what a research compound supplier should look like — rigorous, transparent, and customer-focused.
What Are Alternatives to Science.bio Now?
With Science.bio gone and the broader research vendor market significantly contracted, researchers need to be selective. The market has contracted significantly, and research communities on forums like r/nootropics and r/researchchemicals have ongoing discussions about remaining suppliers. We recommend checking our updated Best SARMs Vendors and Best Peptide Vendors pages for current, vetted alternatives with verified COA documentation.
Frequently Asked Questions
Is Science.bio coming back?
No. The permanent closure announcement is confirmed. The language is explicit: permanently closed. Unlike some past closures, there is no indication of a future relaunch.
I had an outstanding order — what happened?
Science.bio committed to fulfilling all outstanding orders or providing full refunds before shutting down. If you have unresolved issues, you may need to pursue a chargeback through your payment provider.
Was Science.bio shut down by the FDA?
No. The closure was voluntary and business-driven, not the result of a specific enforcement action. It reflects the broader regulatory and commercial pressures facing the entire research compound industry.

i orderd 2 bottles of mk677 and 2 bottles of osterine 4weeks ago and havent received them ywt
Have you received a tracking number?
If not, contact support they will help you!
Why would they come back online and have no stock? I would have stocked my inventory first, the relaunch the website. Very disappointing to say the least
They’ve decided to relaunch with SARMs on preorder, and they’ll slowly be restocking the other items.
Blatantly fake review site! So pathetic and will be blasted everywhere…
never got refund
Placed order and paid with echeck. Cancelled order an hour later because product is contraindicated with my meds. They promised to send refund when echeck cleared, which was 4 days ago. Never got refund and they refuse to answer emails.

Incredible!
Science.bio has returned and is now much better! I’ve previously utilized their products. Their peptides and SARMs are just as pure and powerful as I recall them to be. I’ve always struggled with fighting weariness, but their products have provided much-needed relief.

Science Bio is permanentely closed. I found a post on Reddit from them confirming the closure. In case you want to update your sellers information.
Also about 10 days ago I bought a few things from Swiss Chems and your cupon didn’t work. The delivery was on time, but about the quality I am not so sure.
