EOC Labs - Frequently Asked Questions (FAQ)

For Research Use Only. Not for Human or Veterinary Use.

GENERAL PEPTIDE INFORMATION

1. What are peptides?

Peptides are short chains of amino acids linked by peptide bonds. They occur naturally in the body and are also synthetically produced for laboratory and research purposes. Researchers use peptides to study cellular signaling, regeneration pathways, metabolic activity, and more.

2. How do peptides work?

Peptides act as biological messengers. They bind to specific receptors and can trigger, enhance, or inhibit cellular responses. Each peptide behaves differently depending on its sequence, structure, and research application.

3. Are EOC Labs peptides naturally occurring or synthetic?

All EOC Labs peptides are synthetically manufactured using industry-standard solid-phase peptide synthesis (SPPS) to ensure purity, consistency, and reliable research performance.

4. What is the difference between peptides and proteins?

Proteins are long, complex amino-acid chains. Peptides are shorter and simpler, which makes them ideal for controlled laboratory studies.

5. Are your peptides legal to purchase?

Yes. Research-use peptides are legal to purchase in the United States. No prescription or medical license is required, as long as the products are used strictly for laboratory research.

6. Are your peptides safe for human use?

No. All EOC Labs products are for laboratory research only and not for human consumption, injection, or therapeutic use.

QUALITY, PURITY & TESTING

7. What purity level are your peptides?

All peptides are typically ≥98% purity unless otherwise noted. Each batch undergoes strict quality control.

8. Do you provide Certificates of Analysis (CoA)?

Yes. Every peptide ships with a Certificate of Analysis including:
• HPLC chromatogram
• Mass spectrometry verification
• Purity percentage
• Lot number & manufacturing details

9. How are peptides tested for identity and purity?

EOC Labs uses a combination of:
• High-Performance Liquid Chromatography (HPLC)
• Mass Spectrometry (MS)
• Additional QC assays depending on sequence

10. Why does gross weight differ from net peptide content?

Lyophilized peptides naturally contain small amounts of water, counter-ions, and residual solvents. These affect the gross weight but not purity.

11. Why may the peptide appear fluffy, crystalline, or compact?

Appearance varies depending on amino-acid sequence and freeze-drying behavior. Texture differences do not affect purity or quality

12. Do you offer third-party testing?

Yes. We can coordinate independent mass spectrometry or HPLC testing upon request.

MANUFACTURING & CUSTOM SYNTHESIS

13. How are EOC Labs peptides synthesized?

We use advanced solid-phase peptide synthesis (SPPS) followed by lyophilization and full QC verification.

14. Do you offer custom peptide synthesis?

Yes. Custom sequences, modifications, and kilo-scale orders are available.

15. What modifications can you perform?

Common modifications include:
• N-terminal acetylation
• C-terminal amidation
• PEGylation
• Lipidation
• Disulfide bond formation
• Fluorescent labels

16. What is the maximum peptide length you can produce?

We can typically synthesize sequences up to ~100 amino acids, depending on complexity.

17. What scales do you offer?

• Research vials (5–100 mg)
• Bulk gram quantities
• Kilo-scale manufacturing for commercial partners

18. What is the turnaround time for custom synthesis?

Standard projects take 10–21 business days, depending on sequence, purity, and modifications.

ORDERING, SHIPPING & RETURNS

19. How long will it take for my order to ship?

Most in-stock peptides ship within 1 business day.

20. Do you ship internationally?

Yes. International customers are responsible for verifying import regulations in their region.

21. How are peptides packaged?

Peptides arrive in sealed, sterile, lyophilized vials inside temperature-stable packaging.

22. Do peptides require cold shipping?

Lyophilized peptides are stable at ambient temperatures during normal shipping periods. We recommend refrigeration upon arrival.

23. What if my order arrives damaged?

Contact EOC Labs support within 48 hours. We will replace damaged products at no cost.

24. Do you offer refunds?

For safety and integrity reasons, returns are not allowed on chemical products.
However, defective or incorrect shipments will be replaced.

STORAGE, STABILITY & SOLUBILITY

25. How should lyophilized peptides be stored?

Store sealed vials at −20°C for long-term stability.

26. How should reconstituted peptides be stored?

Most peptides should be stored at 4°C and used within 7–14 days.

27. What solvent should I use for reconstitution?

Solubility varies by peptide sequence. Many dissolve in:
• Bacteriostatic water
• Sterile water
• Acetic acid
• DMSO (for hydrophobic peptides)

28. What if my peptide does not dissolve easily?

Allow gentle agitation. If needed, adjust pH or use a co-solvent like DMSO for difficult sequences.

29. Are peptides stable during shipping temperature changes?

Yes, lyophilized peptides are stable at room temperature for the duration of standard shipping.

LEGAL, COMPLIANCE & SAFETY

30. Are these products for human use?

Absolutely not. EOC Labs products are not drugs, supplements, or medical treatments.

31. Why are the peptides labeled “For Research Use Only”?

This is a legal requirement. The products are intended solely for in-vitro, laboratory, or scientific research.

32. Can you provide medical advice or dosing instructions?

No. EOC Labs cannot provide any medical guidance or human-use recommendations.

33. Do your peptides have side effects?

Research chemicals may exhibit biological activity, but we cannot discuss any human effects.

USAGE & RESEARCH APPLICATIONS

34. What applications are your peptides used for?

Researchers use peptides to study:
• Cell signaling
• Regenerative pathways
• Aging mechanisms
• Metabolic processes
• Tissue modeling
• Protein–protein interactions

35. Are your peptides endotoxin-tested?

Select peptides undergo endotoxin screening; this is available upon request for custom orders.

36. Can these peptides be used in animals?

We cannot authorize or advise on animal or human use.
