GHRP-2

Growth hormone releasing peptide 2

6 residues · 818 Da · 112 atoms

Six residues, three of them D-configuration. Position two is 2-naphthylalanine, the bulky twin-ring side chain that dominates the structure. Studied as a ghrelin receptor ligand.

GHRP-6

Growth hormone releasing peptide 6

6 residues · 873 Da · 121 atoms

Six residues with D-tryptophan at two and D-phenylalanine at five. Two indole rings sit close together in the middle of the chain, which is the most recognisable thing about it.

Hexarelin

Methylated analogue of GHRP-6

6 residues · 887 Da · 125 atoms

Identical to GHRP-6 except for a single methyl group on the indole at position two. That one carbon is the whole difference between the two compounds, and it is drawn here.

Reference entry · not stocked

Ipamorelin

Pentapeptide secretagogue

5 residues · 712 Da · 98 atoms

A five-residue peptide carrying three non-standard residues: alpha-aminoisobutyric acid at position one, D-2-naphthylalanine at three and D-phenylalanine at four. All three are modelled, and the two D residues have their side chains mirrored so they read as distinct from the L form.

Mod GRF 1-29

Sermorelin with four substitutions

29 residues · 3368 Da · 238 atoms

Sermorelin altered at four positions: D-alanine at two, glutamine at eight, alanine at fifteen and leucine at twenty-seven. Each substitution replaces a residue that enzymes cleave or oxidise. Also sold as CJC-1295 without DAC.

Sermorelin

Human GHRH residues 1 to 29

29 residues · 3358 Da · 236 atoms

The first 29 residues of growth hormone releasing hormone, which is the shortest fragment that retains full activity at the receptor. Modelled as an alpha helix.

Tesamorelin

Stabilised human GHRH(1-44)

44 residues · 5136 Da · 361 atoms

All 44 residues of human growth-hormone-releasing hormone with a trans-3-hexenoyl group on the N-terminal tyrosine, which is what blocks dipeptidyl peptidase cleavage. The largest structure in the set - modelled as an alpha helix.

This is a reference index, not a catalogue. Most entries are compounds we do not sell, and they are marked as such. Sequences, residue counts and molecular weights are published properties of the molecule, given for identification. Nothing here describes an application, benefit, dose, route or outcome, and no entry is an offer to supply. Materials sold by PepXtide are for laboratory research use only and have not been evaluated by the FDA.
