Blends and stacks

Peptide combinations sold in one vial (blends) or used together (stacks). Here is what is in each, and whether anyone has tested the combination.

Blend or stack

BPC-157 + TB-500

BPC-157 + TB-500 / Thymosin beta-4

Two tissue-repair peptides sold together, either pre-mixed in one vial or as two vials. Each has mostly animal data on its own.

Pre-mixed blend

GLOW blend

GHK-Cu + BPC-157 + TB-500 / Thymosin beta-4

A trade name for a pre-mixed vial of three peptides. The name and amounts are set by sellers and vary from vendor to vendor.

Pre-mixed blend

KLOW blend

GHK-Cu + BPC-157 + TB-500 / Thymosin beta-4 + KPV

GLOW with KPV added. It is a seller-defined product, and the contents and amounts vary.

Pre-mixed blend

Tri-Heal blend

TB-500 / Thymosin beta-4 + BPC-157 + KPV

A seller-named mix of three peptides promoted for recovery.

Blend or stack

CJC-1295 + Ipamorelin

CJC-1295 + Ipamorelin

Pairs a GHRH analog with a ghrelin-receptor agonist, the two main ways to push the pituitary to release growth hormone.

Blend or stack

CJC-1295 + GHRP-2

CJC-1295 + GHRP-2

Another GHRH-analog-plus-secretagogue pairing, based on the same reasoning as CJC-1295 + ipamorelin.

Blend or stack

Tesamorelin + Ipamorelin

Tesamorelin + Ipamorelin

Combines an FDA-approved GHRH analog (tesamorelin, approved for HIV-associated belly fat) with an unapproved secretagogue.

Pre-mixed blend

AOD-9604 + CJC-1295 + Ipamorelin

AOD-9604 + CJC-1295 + Ipamorelin

A seller-made three-peptide mix promoted for fat loss.

Combination drug in development

CagriSema (cagrilintide + semaglutide)

Cagrilintide (and CagriSema) + Semaglutide

The only combination here that has been tested properly: a fixed-dose pairing of an amylin analog and a GLP-1 drug, made by Novo Nordisk.

Stack

Melanotan II + PT-141

Melanotan II + PT-141 (bremelanotide)

Two closely related melanocortin peptides. PT-141 (bremelanotide) was developed from Melanotan II.
