Common Peptide Abbreviations
Peptide research literature and community discussions are dense with abbreviations that can confuse newcomers. This reference guide decodes the most common abbreviations you will encounter, organized by category for quick lookup.
Key Takeaways
- BPC-157, TB-500, GHK-Cu, and other compound abbreviations each represent specific amino acid sequences
- HPLC and MS on a COA confirm purity and correct molecular identity of a peptide batch

Frequently Asked Questions
What is the difference between mcg and mg in peptide dosing?
One milligram (mg) equals 1,000 micrograms (mcg). This is a critical distinction because many peptide doses are in the microgram range (e.g., 250 mcg of Ipamorelin). Confusing mg for mcg would result in a 1,000x overdose. Always double-check your units when calculating doses and converting between measurement systems.
What does "DAC" mean in CJC-1295 DAC?
DAC stands for Drug Affinity Complex. It is a chemical modification added to the CJC-1295 peptide that allows it to bind to albumin in the blood, dramatically extending its half-life from about 30 minutes to 6-8 days. This is why CJC-1295 without DAC requires daily dosing while CJC-1295 with DAC can be dosed weekly.
Why do some peptides have numbers in their names?
The numbers typically refer to the amino acid sequence position, a compound development number, or a fragment identifier. BPC-157 is the 157th compound in the Body Protection Compound series. AOD-9604 uses a development code number. TB-500 refers to the 500-dalton active fragment of Thymosin Beta-4. These naming conventions vary by discoverer and historical context.
