Question 1

What is Methylene Blue Tablets 20 mg × 30?

Accepted Answer

Methylene Blue (methylthioninium chloride) is a phenothiazine dye with redox-active properties (standard potential E°' ≈ +11 mV vs NHE at pH 7). The compound accepts and donates electrons in the mitochondrial electron transport chain, offering an alternative electron route that bypasses dysfunctional complex I in research models. Investigated for over a century in clinical chemistry, methylene blue has an FDA-approved indication for methemoglobinemia and is studied for neuroprotective and mitochondrial-efficiency applications. Each box contains 30 compressed USP-grade tablets at 20 mg per tablet (600 mg total active substance).

Question 2

What purity is guaranteed?

Accepted Answer

All peptides undergo HPLC analysis with a guaranteed minimum purity of 98%. In practice, most batches reach 99% or higher — the exact value for your specific batch is documented in the Certificate of Analysis (COA) we ship with every order, issued by an independent accredited laboratory. The COA also documents identity and molecular weight. Additional analytical data is available on request.

Question 3

How should I store this peptide?

Accepted Answer

Store lyophilized peptides at -20C in a dark, dry environment. In this form, stability is maintained for up to 24 months. After reconstitution, the solution remains stable for 2-4 weeks at 2-8C. Avoid repeated freeze-thaw cycles — aliquot as needed.

Question 4

Do you provide a Certificate of Analysis?

Accepted Answer

Yes. Every batch ships with a Certificate of Analysis (COA) from an independent laboratory. The document includes an HPLC chromatogram with purity data and mass spectrometry analysis confirming molecular identity. COA files are available for download on the product page or sent via email with the order.

Question 5

Where do you ship?

Accepted Answer

We ship to Bulgaria (1-2 business days via Econt or Speedy) and all EU member states (3-7 business days via international courier). All shipments are discreetly packaged and temperature-controlled when required.

Question 6

What is your return policy?

Accepted Answer

Unopened products in original packaging may be returned within 14 days of receipt for a full refund. Due to the nature of research reagents, opened products cannot be accepted. For defective products, we cover return shipping and issue a full refund.
