If you bought from Science.bio, you got the better end of a bad situation. When the company announced on January 27, 2026, that it was closing for good, it did something most of the others did not. It committed to fulfilling outstanding orders or refunding them before it shut the doors. That is rare, and Science.bio deserves credit for it.
But credit does not change the result. Your vendor is gone, and you need a new one. The question now is the same one every displaced researcher is asking. Where do I buy, and how do I make sure the next one does not disappear too.
What happened to Science.bio
Science.bio closed voluntarily and permanently in late January 2026. It did not publish a detailed explanation, but the timing tells most of the story. The closure landed in the middle of the heaviest enforcement period the research peptide market has ever seen.
What set Science.bio apart was how it left. Rather than going dark and keeping people's money, it wound down in a way that honored open orders. If you were a customer, you were treated fairly on the way out. That is worth saying plainly, because it is the exact opposite of how some other closures went.
You were not the only ones
Science.bio was not an isolated case. It was part of a broad collapse that took down a long list of vendors between the middle of 2025 and early 2026. Among the names that closed or went offline in that window were Peptide Sciences, Amino Asylum, Paradigm Peptides, Royal Research, and several more. At least eight major vendors disappeared in under a year.
The pressure behind the wave was the same across the board. The FDA escalated enforcement, sending more than fifty warning letters to GLP related operations in September 2025 alone, and agents physically raided at least one major vendor's warehouse. Pharmaceutical companies pursued litigation over patented compounds. Payment processors started treating peptide sales as high risk and cutting vendors off. For a lot of operations, staying open simply stopped being worth it.
Not every vendor handled the exit like Science.bio did. Peptide Sciences, the largest of them all, shut down on March 6, 2026, with no refund process at all, which left its customers out both the product and the money. So the bar for your next vendor is not just quality. It is whether they are built to stick around, and whether you can get your hands on what you paid for.
What to look for now
The 2026 shakeout handed every researcher a checklist for picking a replacement. A vendor worth your trust should clear all of it.
- Documentation you can see before you buy. A real per batch Certificate of Analysis with HPLC purity and mass spectrometry data, not a vague promise or paperwork available only on request.
- A way to not prepay into a void. The thing that burned people most was sending money to an operation that could vanish. Anything that lets you complete the deal in person removes that risk.
- A real point of contact. A physical address and an actual human, not just a checkout page and an email that might stop being answered.
- A track record you can verify. History and reviews that go back, not a site that appeared last month to catch the traffic.
- A deep, honest catalog. Broad enough to be your one stop, documented enough that you trust every line.
Why Peptide Hackers fits
Peptide Hackers is built around that exact list.
Every product carries a per batch Certificate of Analysis with HPLC verified purity of ninety nine percent or higher and mass spectrometry confirmation. Recent lots have come back at figures like 99.579% on Retatrutide and 99.505% on Tirzepatide. The catalog runs more than fifty six research compounds across the major classes, all at peptidehackers.com.
The part no mail order vendor can match is the storefront. Peptide Hackers runs two physical locations, one in Los Angeles at 2029 Century Park East in Century City, and one in Newport Beach at 4695 MacArthur Court. You can order online and pick up the same day in person, see the product, get the paperwork in hand, and settle the order at the counter. Andrew and Bryant handle pickup at the Newport Beach office. Shipping is available too if you prefer delivery.
That physical presence is the real answer to the fear the shakeout created. A company with two storefronts, posted hours, and walk in pickup is far harder to make disappear than a website. You cannot get ghosted by a company you can walk into.
Science.bio treated you well on the way out. The next vendor should treat you well by being impossible to vanish on you in the first place. You can browse the full catalog and see live Certificates of Analysis at peptidehackers.com, or schedule a same day pickup in Los Angeles or Newport Beach.
