Product Information
1. What are peptides?
Peptides are short chains of amino acids linked by peptide bonds. They function as biological signaling molecules involved in cellular communication and are widely studied in research involving metabolism, immune function, tissue repair, and other physiological pathways.
2. How do peptides differ from proteins?
Peptides generally consist of 2–50 amino acids, while proteins are much larger molecules composed of longer amino acid chains. Peptides primarily function as signaling molecules, whereas proteins often serve structural, enzymatic, or transport roles.
3. What types of peptides does Peptaro offer?
Peptaro offers research peptides across multiple scientific research categories, including:
Weight Management Research
Recovery & Regenerative Research
Longevity & Cellular Research
Beauty & Skin Research
Cognitive & Neuro Research
Immune & Wellness Research
Hormone & Reproductive Research
Mitochondrial & Energy Research
Muscle Growth & Performance Research
4. Are your peptides synthetic?
Yes. All Peptaro peptides are produced using advanced Solid-Phase Peptide Synthesis (SPPS) technology to ensure high purity, consistency, and batch-to-batch reliability.
5. What purity are your peptides?
Our research peptides are manufactured to ≥99% purity, verified through HPLC and Mass Spectrometry (MS) analysis.
6. How do you verify product quality?
Every production batch undergoes comprehensive quality control, including:
HPLC Purity Testing
Mass Spectrometry Verification
Batch Identity Confirmation
Quality Inspection
Each batch is supported by a Certificate of Analysis (COA).
7. Do you provide Certificates of Analysis (COA)?
Yes.
Every product batch includes a batch-specific Certificate of Analysis (COA), available directly from the product page.
8. Is Peptaro a manufacturer or reseller?
Peptaro operates as both a manufacturer and a distribution partner.
Our core peptides are manufactured in-house using SPPS technology, purified by preparative HPLC, lyophilized, and analytically verified.
To expand our product selection, we also collaborate with carefully vetted manufacturing partners. Every partner-produced product undergoes the same Peptaro quality control process before distribution.
9. What vial sizes do your peptides come in?
Most peptides are supplied in 3 mL sterile glass vials.
Certain products are available in 10 mL vials, which are clearly identified on each product page.
10. Do you sell pre-mixed liquid peptides?
No.
All products are supplied as lyophilized (freeze-dried) powder to maximize product stability and shelf life.
11. How should I store lyophilized peptides?
Before reconstitution:
Refrigerate for routine storage.
For long-term storage, freezing is recommended.
Protect from heat, moisture, and direct sunlight.
12. How should I store reconstituted peptides?
After reconstitution:
Store at 2–8°C (36–46°F).
Do not freeze.
Minimize repeated temperature fluctuations.
13. How long do peptides remain stable?
Lyophilized peptides can remain stable for 1–2 years when properly frozen.
After reconstitution, most peptides are best used within 28 days when refrigerated.
14. What solvent should I use for reconstitution?
Common laboratory solvents include:
Bacteriostatic Water (recommended)
0.6–1% Acetic Acid
DMSO (for certain hydrophobic peptides)
Always follow the recommended reconstitution instructions provided with each product.
15. Are your peptides sterile?
Our peptides are manufactured under strict quality standards and tested to meet research-grade specifications.
They are intended strictly for laboratory research use only.
16. Do your peptides contain preservatives?
No.
Our products contain no unnecessary fillers, preservatives, or additives.
17. Can I request peptides not listed on your website?
Yes.
We continually expand our catalog. If you're looking for a peptide not currently listed, please contact our team regarding availability or future releases.
18. Do you offer peptide blends?
Yes.
Selected research blends are available, including:
BPC-157 / TB-500
CJC-1295 / Ipamorelin
GHK-Cu / TB-500
Cagrilintide / Semaglutide
