Science.bio, a well-regarded US supplier of research compounds, nootropics, and peptides, announced its permanent closure on January 27, 2026. Unlike Amino Asylum or Paradigm Peptides, Science.bio was not raided or criminally charged — the founders chose to close voluntarily, reading the regulatory environment and deciding exit was preferable to enforcement.

The Science.bio closure page confirms: “Science Bio — Permanently Closed.”

Why Did Science.bio Close?

Science.bio’s closure was not triggered by a specific enforcement action. It was a business decision made in response to the converging pressures that also led Peptide Sciences to close six weeks later:

• FDA enforcement escalation: 50+ warning letters in September 2025, physical raids on competitors (Amino Asylum, June 2025), criminal prosecutions (Paradigm Peptides, December 2025)
• Payment processing restrictions: Credit card processors categorizing research compound sales as high-risk or prohibited
• Pharmaceutical litigation: ITC General Exclusion Orders blocking tirzepatide imports
• Legislative direction: The proposed SAFE Drugs Act signaling congressional intent to eliminate the research-use-only framework for FDA-approved drug analogs

For a company with a legitimate business and employees, the calculation shifted: the risk of continuing outweighed the reward.

What Science.bio Sold

Science.bio operated as a broad research compound supplier — wider than a pure peptide vendor. Their catalog included:

• Nootropics (racetams, modafinil analogs, cognitive research compounds)
• Research peptides (BPC-157, TB-500, growth hormone secretagogues)
• SARMs
• Other research chemicals

For researchers who purchased peptides from Science.bio specifically, the replacement search is straightforward. For the broader nootropics/research chemical catalog, options are more limited as the regulatory environment has contracted.

Science.bio Alternatives for Research Peptides

For the peptide portion of the Science.bio catalog, Life Link Research is a direct replacement with upgraded COA standards. Science.bio had a reasonable reputation for consistency, but their COA documentation varied by product category.

Life Link Research provides third-party independent COAs (HPLC, mass spectrometry, endotoxin, sterility, moisture, amino acid composition) on every batch of every peptide product. The GLP-1 research peptide range — semaglutide, tirzepatide, retatrutide, CagriSema — covers the compounds most active in current research.

FAQs

Is Science.bio coming back?

No. The permanent closure announcement is confirmed. Unlike Amino Asylum or Paradigm, the closure was voluntary and the language is explicit: permanently closed.

Were Science.bio products good quality?

Science.bio had a generally positive reputation in research communities for their core products. The closure was business-driven, not quality-driven. Researchers who had good experiences with Science.bio’s products are likely to find equivalent or better quality at LLR for the peptide categories.

What is the best Science.bio alternative for research peptides?

Life Link Research, for peptide-specific research. For the broader nootropic and research chemical categories Science.bio covered, the market has contracted significantly. Research communities (r/nootropics, r/researchchemicals) have ongoing discussions about remaining suppliers.

Does Life Link Research carry nootropics?

No. Life Link Research specializes in research peptides. We don’t supply racetams, SARMs, or general research chemicals. Our focus on peptides means our COA program is built specifically for peptide verification standards.
