CJC-1295 مقابل Ipamorelin

CJC-1295 (with DAC) is a 30-residue modified GRF(1-29) analog carrying an albumin-binding DAC group, characterized at the GHRH receptor. Ipamorelin is a 5-residue synthetic peptide (Aib, D-2-Nal, D-Phe) characterized at GHSR-1a. They differ in receptor class, length, and molecular weight (3647.2 vs 711.9 g/mol).

Semax مقابل Selank

Semax and Selank are both synthetic heptapeptides ending in the same Pro-Gly-Pro extension, but they start from different parent sequences. Semax (MEHFPGP) extends the ACTH(4-7) fragment; Selank (TKPRPGP) extends tuftsin. Semax contains methionine, so its formula carries sulfur (C37H51N9O10S, 813.93 g/mol); Selank is C33H57N11O9 at 751.89 g/mol.

Ipamorelin مقابل Tesamorelin

Ipamorelin and Tesamorelin are ligands for different receptor classes and differ greatly in size. Ipamorelin is a 5-residue synthetic peptide (Aib, D-2-Nal, D-Phe) characterized at GHSR-1a, at 711.9 g/mol. Tesamorelin is a 44-residue GHRH(1-44) analog with an N-terminal trans-3-hexenoyl cap, characterized at the GHRH receptor, at 5135.9 g/mol.

CJC-1295 مقابل Tesamorelin

CJC-1295 and Tesamorelin are both GHRH analogs characterized at the GHRH receptor, but they are built differently. CJC-1295 (with DAC) is a 30-residue modified GRF(1-29) carrying an albumin-binding DAC group (3647.2 g/mol). Tesamorelin is a 44-residue GHRH(1-44) analog with an N-terminal trans-3-hexenoyl cap (5135.9 g/mol).

GHK-Cu مقابل BPC-157

GHK-Cu and BPC-157 differ in size and composition. GHK-Cu is a copper(II) complex of the tripeptide Gly-His-Lys (C14H22CuN6O4, ~401.9 g/mol). BPC-157 is a linear 15-residue peptide, GEPPPGKPADDAGLV (C62H98N16O22, 1419.56 g/mol), with no bound metal. Both are supplied as lyophilized powder.

PT-141 مقابل MT-2

PT-141 and MT-2 are cyclic lactam heptapeptides in the melanocortin family with nearly identical structures. The difference is at the C-terminus: MT-2 ends in an amide (C50H69N15O9, 1024.2 g/mol), while PT-141 ends in a free acid (C50H68N14O10, 1025.2 g/mol). Both are characterized in melanocortin-receptor binding assays.

MOTS-c مقابل NAD+

MOTS-c and NAD+ belong to different compound classes. MOTS-c is a 16-residue mitochondrial-derived peptide (MRWQEMGYIFYPRKLR; C101H152N28O22S2, 2174.6 g/mol). NAD+ is not a peptide but a dinucleotide redox coenzyme (C21H27N7O14P2, 663.43 g/mol). In vitro, MOTS-c is characterized in cell-signaling assays, while NAD+ serves as an enzyme cofactor in biochemical assays.

BPC-157 مقابل TB-500

BPC-157 is a defined synthetic pentadecapeptide (GEPPPGKPADDAGLV; C62H98N16O22, 1419.56 g/mol, CAS 137525-51-0). TB-500 is a Thymosin β-4-derived peptide: the name is used for either the Ac-LKKTETQ actin-binding fragment (~889 Da) or full Thymosin β-4 (~4963 Da), so its exact identity is set lot by lot rather than by a single CAS number.

GHRP-2 مقابل GHRP-6

GHRP-2 and GHRP-6 are both synthetic hexapeptides that contain D-amino acids and end in a C-terminal amide. They differ in sequence and composition: GHRP-6 is His-D-Trp-Ala-Trp-D-Phe-Lys-NH₂ (C46H56N12O6, 873.0 g/mol), while GHRP-2 is C45H55N9O6 at 818.0 g/mol. Both are supplied as lyophilized powder.

AHK-Cu مقابل GHK-Cu

AHK-Cu and GHK-Cu are copper(II) complexes of closely related tripeptides that differ only in the first residue: L-alanine in AHK (Ala-His-Lys) versus glycine in GHK (Gly-His-Lys). AHK-Cu is indexed as the monohydrochloride (C15H24ClCuN6O4, 451.39 g/mol, CAS 682809-81-0); GHK-Cu is C14H22CuN6O4 at ~401.9 g/mol (CAS 89030-95-5).
