Chemyo vs Science.bio 2026 — Which SARMs Supplier Is Better for Research?

The Chemyo vs Science.bio comparison is one of the most searched in the research compound space — and in 2026 it carries a different weight than it used to. Science.bio was widely considered the gold standard for SARM testing transparency before its permanent closure in January 2026. Chemyo (chemyo.io) is the active alternative that most closely matches what Science.bio stood for: independent third-party testing, batch-specific COAs, and 99%+ purity as a non-negotiable standard. This page breaks down exactly how the two vendors compare across every metric that matters.

Chemyo vs Science.bio — What Happened to Science.bio?

Science.bio (formerly IRC.bio) launched in April 2019 after its predecessor shut down due to federal regulatory complications. Over the following six years it built arguably the strongest testing reputation in the research compound market — using a testing suite that included HPLC, NMR spectroscopy, TLC, ICP-MS, microbiology panels, and GC-MS across its entire product catalog. Independent reviewers consistently cited Science.bio as the benchmark for COA transparency in the space.

Then, on January 27, 2026, Science.bio sent its final email and permanently closed. The same regulatory compliance pressure that had reshaped the research chemical market for the preceding two years caught up with one of its most trusted names. The subreddits responded immediately. Thousands of researchers who relied on Science.bio for SARMs, nootropics, and peptides needed a new verified source overnight.

For researchers now asking Chemyo vs Science.bio — which one should I use? — the answer in 2026 is straightforward: Science.bio is no longer an option. Chemyo at chemyo.io is the most direct quality-matched replacement. Here is a full breakdown of how they compare across every metric that defined Science.bio’s reputation.

Chemyo vs Science.bio — Testing Standards Compared

Testing transparency was the core of Science.bio’s brand. Here is exactly how the two vendors stacked up:

Science.bio Testing (historical)

Science.bio used a comprehensive multi-method QC process on every product in their catalog: HPLC for purity quantification, NMR (Nuclear Magnetic Resonance) spectroscopy for structural identity confirmation, TLC (Thin Layer Chromatography) for rapid screening, ICP-MS for heavy metals, and a full microbiology panel for biological contaminant screening. Their FAQ page explicitly stated that their general purity standard was ≥98% by HPLC, with many products testing at ≥99%. They verified every batch of every product and published independent third-party analysis on every product listing.

Chemyo Testing (chemyo.io — active)

Chemyo uses three independent tests on every batch: FTIR (Fourier-Transform Infrared Spectroscopy) for molecular identity, HPLC for purity quantification with a 99%+ threshold, and a separate HPLC concentration assay on every finished solution to confirm the actual mg/ml matches the label. Raw powders are purified through recrystallization to hit the 99%+ threshold. All testing is conducted by independent third-party laboratories. Batch-specific COAs are publicly posted on every product page before purchase.

Chemyo vs Science.bio — Pricing & Value Per Milligram

One of the most discussed aspects of the Chemyo vs Science.bio debate was pricing. Science.bio was generally cheaper per bottle but Chemyo’s 50ml format often won on price-per-milligram. Here is the historical comparison:

• Science.bio RAD-140: $34.99 for 30ml at ~10mg/ml = 300mg total = $0.117/mg
• Chemyo RAD-140: $79.99 for 50ml at 10mg/ml = 500mg total = $0.160/mg
• Science.bio Ostarine: $29.99 for 30ml at 25mg/ml = 750mg total = $0.040/mg
• Chemyo Ostarine: $69.99 for 50ml at 25mg/ml = 1,250mg total = $0.056/mg

Science.bio was cheaper per milligram on most SARMs. However, two factors closed the gap considerably for many researchers:

1. Science.bio’s 10% credit card surcharge — a $35 Science.bio order became $38.50 by card. Chemyo charges zero card surcharge.
2. Science.bio’s no international shipping policy — international researchers could not access Science.bio at any price. Chemyo ships internationally with free shipping on orders over $275.

For US-based researchers paying by crypto or eCheck, Science.bio was typically better value per mg. For card-paying or international researchers, the gap narrowed significantly or reversed. In 2026, with Science.bio closed, this comparison is academic — chemyo.io is the active option.

The website is offline and orders cannot be placed. chemyo.io is the closest active alternative matching Science.bio’s purity and COA transparency standards.
• Which is better — Chemyo or Science.bio? +
  In 2026, this comparison is one-sided: Science.bio is permanently closed. For researchers who need to source research compounds, chemyo.io is the active vendor that most closely matches Science.bio’s quality standard — independent third-party testing, batch-specific COAs, 99%+ purity, and a transparent supply chain. Chemyo adds advantages Science.bio lacked: 50ml bottles (vs 30ml), zero credit card surcharge (vs 10%), and international shipping.
• What is the best Science.bio alternative in 2026? +
  chemyo.io is the most direct Science.bio alternative in 2026 for SARMs and nootropic research. Both vendors built reputations on independent third-party COA testing and 99%+ purity standards. Chemyo offers 50ml bottles vs Science.bio’s 30ml, same-day US shipping, zero credit card surcharge, international shipping, and a growing nootropic and peptide range.
• Did Science.bio have better testing than Chemyo? +
  Science.bio used a broader testing suite than most vendors: HPLC, NMR spectroscopy, TLC, ICP-MS for heavy metals, and a full microbiology panel. This was widely considered the most technically rigorous testing methodology in the research compound market. Chemyo uses FTIR identity testing, HPLC purity testing (99%+ required), and HPLC concentration assay on every finished solution — a strong three-point standard, though narrower than Science.bio’s suite. Chemyo’s testing is excellent by industry standards and all results are independently third-party verified.
• Was Chemyo or Science.bio cheaper? +
  Science.bio was generally cheaper per bottle and per milligram than Chemyo on most SARMs. For example, RAD-140 at Science.bio was historically around $34.99/30ml ($1.17/ml) vs Chemyo’s $79.99/50ml ($1.60/ml). However, Science.bio charged a 10% credit card surcharge that closed the gap for card-paying customers. Science.bio also did not ship internationally, limiting its accessibility. Chemyo charges zero card surcharge and ships internationally, which changes the effective price comparison for many researchers.
• Does Chemyo ship internationally like Science.bio? +
  Science.bio historically did not offer international shipping — a significant limitation for global researchers. chemyo.io ships internationally with free international shipping on orders over $275. For researchers outside the USA who could never use Science.bio, chemyo.io resolves that barrier entirely.
• Does Chemyo have nootropics like Science.bio did? +
  Yes. chemyo.io carries a growing nootropics range including Noopept Solution, 9-ME-BC Powder, Bromantane Solution, Unifiram Powder, and more. Science.bio had a broader 200+ product nootropic catalog at its peak. Chemyo’s nootropic range is smaller but is independently tested to the same 99%+ purity standard with batch-specific COAs.
• Why did Science.bio close? +
  Science.bio permanently closed in January 2026 and cited regulatory compliance pressure as the reason for closure. This was consistent with a broader regulatory tightening that reshaped the research chemical vendor market over the preceding two years, forcing multiple vendors to restrict their catalogs, exit product categories, or close entirely. Science.bio sent its final customer email on January 27, 2026.
