Peptide Reference Directory: Names and Documentation
This directory explains names and chemical-reference fields for the peptide listings in the Astra catalog. It provides factual terminology and documentation questions, without health, weight-loss, recovery, or performance claims.
Start with the full compound name
Compare the exact chemical form, sequence or structure, and label units. A public database entry and a published study describe their own reference material. Neither verifies the contents, purity, or identity of a commercial batch.
Dedicated references are available for tirzepatide, retatrutide / Reta, MOTS-c, BPC-157, and GHK-Cu.
Epithalon / Epitalon
PubChem records Epitalon under CID 219042 and includes Epithalon as a synonym. Its reference sequence is Ala-Glu-Asp-Gly, abbreviated AEDG: four amino-acid residues. That sequence and a label quantity in milligrams answer different questions. The database identity does not verify a supplied sample.
Catalog listings: Epithalon 10mg · Epithalon 50mg
Reference: PubChem: Epitalon.
Ipamorelin
PubChem identifies ipamorelin under CID 9831659, with the reference formula C38H49N9O5. The formula refers to the recorded structure. Confirm whether a supplied material is represented by that structure or another chemical form; a peptide name alone does not establish the counterion or total material composition.
Catalog listings: Ipamorelin 10mg
Reference: PubChem: ipamorelin.
KPV
KPV abbreviates lysine-proline-valine, a three-residue peptide. A published analytical paper describes an HPLC method for KPV; that publication is a reference for the authors’ method, not proof that an Astra batch underwent that test. A report would need its own sample identifier, method, and results.
Catalog listings: KPV 10mg
Reference: Published KPV analytical-method reference, PMID 25298219.
Selank
PubChem records Selank under CID 11765600 with the reference formula C33H57N11O9. Match the exact record and chemical form when reviewing a specification. Chemical identifiers describe structure; they do not establish effects, suitability, or sample purity.
Catalog listings: Selank 10mg
Reference: PubChem: Selank.
Semax
PubChem’s Semax record, CID 9811102, represents the seven-residue sequence Met-Glu-His-Phe-Pro-Gly-Pro, abbreviated MEHFPGP. A separate acetylated or otherwise modified peptide requires its own specification. Shared name fragments are not sufficient evidence that two materials have identical structures.
Catalog listings: Semax 10mg
Reference: PubChem: Semax reference structure.
SS-31 / Elamipretide
PubChem lists SS-31 among the synonyms for elamipretide, CID 11764719, with the reference formula C32H49N9O5. Use both names when locating the reference, then confirm the supplied chemical form. A synonym match is a starting point for documentation, not a laboratory identity result.
Catalog listings: SS-31 10mg
Reference: PubChem: elamipretide.
PT-141 / Bremelanotide
PubChem associates PT-141 with bremelanotide, CID 9941379, and gives the reference formula C50H68N14O10. A record for a reference structure does not verify a catalog batch or equate it with a finished pharmaceutical product. Check chemical form, label units, and batch documentation separately.
Catalog listings: PT-141 10mg
Reference: PubChem: bremelanotide / PT-141.
Melanotan naming
The reviewed Astra description identifies its Melanotan listing as Melanotan II. PubChem’s melanotan-II record has CID 92432 and reference formula C50H69N15O9. Keep the complete identifier, including the numeral, when comparing references; do not infer a chemical identity from “Melanotan” alone.
Catalog listings: Melanotan 10mg
Reference: PubChem: melanotan-II.
Tesamorelin
PubChem records tesamorelin under CID 16137828, with reference formula C221H366N72O67S. It also contains separate acetate records. These entries show why a supplier should specify the chemical form rather than copying a formula from a loosely matched name. No chemical form for an Astra batch is verified by this directory.
Catalog listings: Tesamorelin 10mg
Reference: PubChem: tesamorelin.
CJC-1295 No DAC: clarify the modifier
Astra’s catalog explicitly labels this item “No DAC.” The original CJC-1295 characterization describes a chemically modified peptide with a reactive group used in albumin conjugation. Its specification should not be silently transferred to a listing marked No DAC. Request the exact sequence, modifications, and chemical form before assigning a molecular formula or mass.
Catalog listings: CJC-1295 No DAC 10mg
Reference: Original CJC-1295 chemical-characterization paper, PMID 15817669.
TB-500: specify the peptide fragment
An analytical publication identified an acetylated thymosin beta-4 fragment in a preparation named TB-500. A fragment and the full-length parent peptide are different references. The publication does not identify Astra’s material; its exact sequence and terminal modifications require a supplier specification and matching analytical evidence.
Catalog listings: TB-500 10mg
Reference: TB-500 fragment characterization, PMID 22962027.
Peptide blends and catalog names
CJC / Ipamorelin Blend combines CJC No DAC and ipamorelin. Wolverine combines BPC-157 and TB-500. Check the product specification for the individual component amounts in these blends.
Glow 70 commonly refers to a three-peptide blend containing GHK-Cu 50 mg, BPC-157 10 mg, and TB-500 10 mg, totaling 70 mg per vial. The 70 mg figure is the combined amount of the three components, not 70 mg of each ingredient or a concentration in mg/mL. Formulation specifications and batch-specific analytical test results are separate information.
Catalog listings: CJC / Ipamorelin Blend 10mg · Glow 70 · Wolverine (BPC-157 + TB-500) 20mg
Testing availability and interpretation
Astra Biolabs does not currently offer lab reports for the peptide listings covered here. No testing result for another item should be inferred for a peptide listing.
A milligram label is not a chromatographic purity percentage or an identity test. A blend total does not establish the amount of each ingredient. Read the COA checklist and analytical-methods guide when reviewing documentation.
