Question 5

What purity level are your peptides and how is it verified?

Accepted Answer

All AllMyPeptides products are guaranteed to be 99%+ pure. Purity is verified through independent third-party HPLC (High Performance Liquid Chromatography) analysis at independent laboratories. Each batch receives a Certificate of Analysis confirming the exact purity percentage, typically ranging from 99%+ to 99%+.

Question 6

What is a Certificate of Analysis (COA) and how do I read it?

Accepted Answer

A Certificate of Analysis is a formal document from an independent testing laboratory that verifies a compound's identity, purity, and quality. Each COA includes: the product name and batch number, test date, testing method (HPLC/MS), purity percentage, endotoxin levels, molecular weight confirmation, and appearance verification. You can verify any COA by entering your batch lot number on our COA Library page.

Question 7

What is HPLC testing?

Accepted Answer

High Performance Liquid Chromatography (HPLC) is an analytical technique used to separate, identify, and quantify components in a mixture. For peptide purity testing, HPLC separates the target peptide from any impurities or byproducts. The purity percentage is calculated using peak area integration: Purity (%) = (Area of Target Peak / Sum of All Peaks) x 100.

Question 8

What is Mass Spectrometry and why does it matter?

Accepted Answer

Mass Spectrometry (MS) is an analytical technique that measures the mass-to-charge ratio of molecules. For peptides, MS confirms the molecular weight matches the theoretical sequence, verifying identity. When combined with HPLC (LC-MS), it provides both purity and identity confirmation, ensuring you receive the exact compound ordered.

Question 9

How do I verify my batch against the COA?

Accepted Answer

Each vial has a unique batch lot number printed on the label. Enter this lot number on our COA Library page or homepage verification tool to view the complete Certificate of Analysis for your specific batch, including the chromatogram and all test results.

Question 10

What is lyophilised (freeze-dried) peptide?

Accepted Answer

Lyophilisation (freeze-drying) is a process that removes water from a frozen peptide solution through sublimation. This creates a stable powder that can be stored long-term. Lyophilised peptides are reconstituted with bacteriostatic water before use in research protocols.

Question 11

How long are your peptides stable?

Accepted Answer

Lyophilised peptides stored at -20°C remain stable for 2+ years. At 2-8°C (refrigerated), they are stable for up to 6 months. Once reconstituted, peptides should be used within 30 days when stored at 2-8°C. Always check the COA for batch-specific stability data.

Question 12

What are blends/stacks?

Accepted Answer

Blends are pre-formulated combinations of multiple peptides designed for synergistic research. For example, our GLOW Blend combines BPC-157, TB-500, and GHK-Cu for comprehensive tissue repair and ECM research. Each blend is formulated with specific ratios based on research protocols.

Question 13

Question 23

How should I store lyophilised peptides?

Accepted Answer

For long-term storage (2+ years), keep lyophilised peptides at -20°C (freezer). For storage up to 6 months, 2-8°C (refrigerator) is sufficient. Keep away from direct light and avoid repeated freeze-thaw cycles.

Question 24

How should I store reconstituted peptides?

Accepted Answer

Reconstituted peptides must be stored at 2-8°C (refrigerator) and used within 30 days. Do not freeze reconstituted solutions. Always label the vial with the reconstitution date.

Question 25

What is bacteriostatic water?

Accepted Answer

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. It is used to reconstitute lyophilised peptides. The benzyl alcohol prevents bacterial growth, allowing the reconstituted solution to be stored safely for up to 30 days.
