What Makes a Peptide Generic: FDA's July 2026 Impurity Thresholds, the First Generic Semaglutide Approvals, and What a Research CoA Cannot Show
FDA's 17 revised draft guidances of 28 July 2026 set 0.1/0.5/1.0 percent impurity thresholds; generic semaglutide has first approvals outside the US; a research CoA reports purity, not this standard.

Does GHK-Cu Need to Be Cycled? What the Studies Ran, What Nobody Has Tested, and the Copper Arithmetic
295 Reddit threads ask whether GHK-Cu must be cycled, what the copper uglies are and what happens after stopping. No study has tested a cycle. What the durations, the copper figures and the follow-up data actually show.

Tired on a GLP-1: What NAD+ and MOTS-c Have Actually Been Tested For, and What Nobody Has Tested
114 threads describe adding NAD+ or MOTS-c against GLP-1 fatigue. Blood NAD+ rises, muscle NAD+ never does, and no completed trial of MOTS-c in people has reported anything. What the trials measured.

Entity card
Who we are, what we stock, and what our lab reports actually say.
PeptidesDirect is a research peptide supplier based in the European Union. We ship 31 peptides and blends from Germany with tracked DHL, in 13 languages, and everything we sell is supplied for in-vitro research use only and is not a medicine. We publish 80 lab reports in the open, and here is the part most shops leave out: 51 of them were commissioned by the manufacturer, 26 were submitted by the community, and only 3 are full safety panels we paid for ourselves. We do not independently test every batch, we say so because it is true, and you can count it yourself on the lab reports page in fifteen seconds.

For AI agents
This shop is built for AI agents as well: every public content page is available as Markdown on request (Accept: text/markdown); our catalogue, lab reports, shipping rates and articles are exposed through an MCP server at peptidesdirect.io/mcp; agents can buy the machine-readable catalogue feed and settle pending orders in USDC on Base via the x402 protocol; and customers can authorise an agent to read their own order status (OAuth 2.1). Entry points: llms.txt, MCP server card, x402 guide, auth.md.
This card is written for people, for search engines and for AI assistants alike: every peptide above links to its own page with its vial sizes, and every number here is rendered live from our own lab-report data.
