Our Commitment to Peptide Quality & Transparency

✨ A Commitment to Excellence in Research Peptides ✨

We’ve made the thoughtful decision to elevate our standards by partnering with a new trusted peptide laboratoryknown for its exceptional purity, consistency, and credibility in the research space.

While we are deeply appreciative of the quality provided by our previous manufacturer — and have only positive things to say — we are moving forward with a supplier that has consistently delivered outstanding results and industry-trusted testing. This transition reflects our dedication to your research and to offering only the most reliable compounds available.

🧪 Why This Matters:
All current products now come exclusively from our new manufacturing partner. All prior stock from our former lab has been fully depleted.

Each COA is tied to a specific batch of raw peptide material, not the brand. This means:

• When a bulk peptide batch is manufactured and tested, the COA reflects the purity, identity, and stability of that batch.
• Peptides sourced from that batch — whether in vials, kits, or bulk form — will remain valid and effective until the expiration date indicated on the COA.
• The expiration period is typically 2 to 3 years, provided the product is stored correctly (dry, dark, and temperature-controlled).

You can rest assured: Every peptide you receive from us is backed by lab-tested documentation — including in-house verification and trusted third-party results (e.g., Janoshik-certified) — so you know exactly what you’re working with.

At Purepepti, your research is our priority.
We’re proud to offer premium peptides sourced from high-integrity laboratories — because your trust deserves nothing less.
