Short version: Royal Research is no longer operating. The only thing that really changed is the bar for picking a replacement — the vendors still standing publish independent, batch-level COAs. Life Link Research clears that bar with a six-test panel on every batch, verified by Janoshik Analytical. Below: how to choose, how the survivors compare, and how to move your research over.
Royal Research has closed — the short version
Royal Research is among at least eight research-peptide vendors reported offline during the 2025–2026 enforcement wave. For the full backstory, see what happened to Royal Research.
The thread connecting the 2025–2026 closures: regulatory pressure landed hardest on vendors that drifted into human-use marketing or operated without verifiable third-party testing. The vendors still shipping are the ones that invested early in independent batch documentation and research-only positioning.
What to check before you pick a replacement
The bar is higher now, and the vendors who clear it are easy to spot. Score any vendor on this checklist:
- Batch-specific COA on every product page — visible and downloadable, not “available on request.”
- An independent analytical lab — Janoshik, Colmaric, or Auriga. A COA on the vendor’s own letterhead doesn’t count.
- LCMS for identity, HPLC for purity. “99% pure” with no method named is a marketing number.
- A verifiable U.S. address — not just “Made in USA” copy.
- Sterility and endotoxin testing on injectable peptides.
- Clear “for research use only — not for human consumption” labeling.
- Responsive support — email a question before you order.
Fail items 1–4 and you should not place an order. New to these documents? See how to read a peptide COA.
Our recommendation: Life Link Research
We’ll be direct, because it’s our site: we built Life Link Research to clear the bar above on the axis that matters most — verification.
- A six-test panel on every batch. Most vendors run two tests (identity + purity); the most rigorous run three or four. We run six: identity (LCMS), purity (RP-HPLC), residual solvents (GC), heavy metals (ICP-MS), endotoxin (LAL), and sterility — each result on the batch COA.
- Independent verification by Janoshik Analytical, the most-cited third-party peptide lab in the industry.
- A full research range, including the GLP-1 family — Semaglutide, Tirzepatide, Retatrutide and CagriSema — plus healing, longevity, and growth-hormone-secretagogue compounds.
- U.S. domestic stock, 2–4 day shipping, discreet packaging, and conservative, research-only copy.

Verify us rather than take our word for it: open any product and confirm the COA is current and batch-numbered in our COA library.
How the surviving vendors compare
All of the vendors below meet the four critical criteria; the column that separates them is how many tests each batch goes through. Public data as of June 2026 — confirm on the vendor’s current site before ordering.
| Vendor | Independent lab | COA per batch | Tests per batch | U.S.-based |
|---|---|---|---|---|
| Life Link Research | Janoshik | Yes | 6 (incl. sterility + endotoxin + heavy metals) | Yes |
| Ascension Peptides | Janoshik | Yes | 2–3 | Yes |
| Core Peptides | Janoshik, Colmaric | Yes | 2 | Yes |
| Felix Chemical Supply | Independent + sterility | Yes | 3–4 | Yes |
| Swiss Chems | Independent (HPLC/MS) | Yes | 2 | Yes |

Moving your research over
| What you sourced | Where to pick it up |
|---|---|
| GLP-1 weight-management peptides | Retatrutide, Tirzepatide, CagriSema |
| Healing & recovery (BPC-157, TB-500, GHK-Cu) | BPC-157 / TB-500 |
| Growth-hormone secretagogues | CJC-1295 / Ipamorelin |
| Longevity (NAD+, Epithalon) | NAD+, Epithalon |
Holding stock bought before the closure? Lyophilized peptides in sealed vials at -20°C stay stable ~24 months; reconstituted at 2–8°C far less. Keep the original COA — see our storage guide.
Frequently asked questions
Is Royal Research still open?
Royal Research is reported to have gone offline during the 2025–2026 research-peptide enforcement wave. Treat the domain as inactive and confirm any vendor’s current status before ordering.
What is the best Royal Research alternative?
Life Link Research — a six-panel independent COA on every batch, a full GLP-1 range, and U.S. domestic shipping. Ascension, Core Peptides, and Felix Chemical also meet the core COA criteria.
Why did Royal Research close?
It went offline during the broad 2025–2026 tightening on research-chemical vendors. See our guide on what happened to Royal Research for detail.
Are research peptides legal in the United States?
Yes — when sold and labeled strictly as research chemicals to qualified researchers, with no claims of human use and all required disclaimers. The 2025–2026 enforcement actions targeted vendors who marketed for human consumption.
All products referenced are intended strictly for laboratory research use and are not for human or veterinary consumption. Statements regarding peptides have not been evaluated by the U.S. Food and Drug Administration. Vendor information reflects publicly available data as of June 2026 and may change; verify any vendor’s current status before ordering.
