GHRP-2 5mg + Tesamorelin 5mg + MGF 500mcg + Ipamorelin 2.5mg Peptides
Engineered for disciplined inquiry, this multi-peptide vial is prepared to support consistent performance across controlled laboratory studies.
This research peptide blend is supplied as a lyophilized powder vial (unflavored) composed of growth-hormone pathway peptides for advanced assay work. The formulation includes GHRP-2, Tesamorelin, MGF, and Ipamorelin, presented in a balanced profile for methodical protocol design. Each vial contains: 5mg GHRP-2, 5mg Tesamorelin, 500mcg MGF, and 2.5mg Ipamorelin.
- 5mg GHRP-2 – A ghrelin receptor agonist commonly selected for studies investigating pulsatile growth hormone signaling and pituitary pathway dynamics.
- 5mg Tesamorelin – A growth hormone–releasing hormone analogue used in research focused on hypothalamic–pituitary axis mechanisms and GH/IGF-1 modulation.
- 500mcg MGF – The mechano growth factor isoform of IGF-1, explored in cellular models assessing satellite cell signaling and tissue remodeling pathways.
- 2.5mg Ipamorelin – A selective ghrelin receptor peptide often used to isolate GH-related responses with minimal off-target pituitary interactions in model systems.
As a non-edible, lyophilized format, the vial is intended for precise, protocol-driven applications where clarity, consistency, and controlled handling matter. Researchers value the clean, uniform matrix that supports predictable reconstitution characteristics and reliable aliquoting. The profile suits comparative assays, pathway characterization, and exploratory work where secretagogue selectivity and complementary signaling activity are of interest.
Quality and integrity are central. Peptide Scientific Labs sources and handles materials in the USA under rigorous laboratory standards. Every lot is tested for identity and purity using validated analytical methods (including HPLC and mass spectrometry), with documentation available by lot number. Packaging is tamper-evident, and handling follows careful, cleanroom-based procedures to support consistency from vial to vial. This product is provided strictly for laboratory research use only. Not for human consumption, medical, or veterinary use. For investigators requiring dependable peptide quality, transparent specifications, and steady supply, this multi-peptide vial reflects the precision and restraint expected in modern research environments.

Frequently Asked Questions
What is TESA/IPA Blend typically studied for?
Researchers generally study this combination for growth-hormone pulse support, IGF-1-related signaling, and body-composition or recovery-oriented endocrine models. The useful nuance for an FAQ is that blends like this are chosen for pathway complementarity, but study relevance still depends on the exact dose ratio disclosed by the vendor.
What is TESA/IPA Blend?
TESA/IPA Blend combines Tesamorelin, a GHRH analog, with Ipamorelin, a ghrelin-receptor agonist. The purpose of the blend is to bring together two different upstream signals that can influence endogenous growth-hormone release. On a site page, it should be described as a research blend for GH-axis and endocrine studies only.
What are GH peptides?
GH peptides — short for growth-hormone-related peptides — are a research category that includes two main subgroups. The first is growth-hormone-releasing hormone (GHRH) analogs, such as Sermorelin, Tesamorelin, and CJC-1295, which are studied for their interaction with the GHRH receptor. The second is growth hormone secretagogues, such as Ipamorelin, GHRP-2, GHRP-6, and Hexarelin, which are studied for their interaction with the ghrelin receptor (GHS-R1a).
Both subgroups are investigated in the research context of growth-hormone-axis biology. All GH peptide products from Peptide Scientific Labs are lyophilized research compounds intended solely for in vitro laboratory investigation.
How do GH peptides differ from recombinant growth hormone?
Recombinant human growth hormone is the full 191-amino-acid human GH protein, produced via recombinant DNA technology. It is essentially identical to the endogenous hormone itself. GH peptides, by contrast, are much shorter sequences — typically on the order of a few to a few dozen amino acids — that do not act as GH themselves but rather engage upstream receptors (GHRH-R or GHS-R1a) involved in the GH signaling axis.
This makes the two categories mechanistically distinct. Recombinant GH is a replacement of the hormone itself, while GH peptides are research tools for studying the regulatory machinery that controls endogenous GH release.
What is the difference between GHRH analogs and GH secretagogues?
GHRH analogs are peptides modeled on the natural growth-hormone-releasing hormone sequence. They are studied for their ability to bind the GHRH receptor on the pituitary — the same receptor used by endogenous GHRH. Examples include Sermorelin (a GHRH 1-29 analog), Tesamorelin, and CJC-1295.
GH secretagogues are a structurally different class of peptides that act through the growth hormone secretagogue receptor (GHS-R1a), better known as the ghrelin receptor. Examples include Ipamorelin, GHRP-2, GHRP-6, and Hexarelin. The two classes engage different receptors and are therefore studied as distinct pharmacological families in research on GH signaling.
