GHK-Cu Research Guide: Mechanism, Dosing & Skin/Wound Studies
GHK-Cu is the copper-bound form of the tripeptide glycyl-L-histidyl-L-lysine. It naturally occurs in human plasma and declines with age. Decades of laboratory work show it modulates wound-healing, antioxidant, and tissue-remodeling genes, which is why it has become one of the most-studied research peptides in dermatology and regenerative biology.

BPC-157 Explained: How It Works, Research Uses & Safety
BPC-157 (Body Protection Compound) is a stable 15-amino-acid pentadecapeptide derived from a protective sequence in human gastric juice. It has been studied for almost three decades for its effects on tissue repair, angiogenesis, gastrointestinal protection, and tendon/ligament healing in animal models.

GLOW Peptide Blend: GHK-Cu + BPC-157 + TB-500 Research Overview
GLOW is the trade name for a three-peptide research blend combining GHK-Cu, BPC-157, and TB-500 in a single lyophilized vial. It is one of the most-purchased research blends in the US peptide market because the three compounds cover complementary tissue-repair pathways.

Tesamorelin: GHRH Analog Mechanism, Visceral Fat Studies & Research Dosing
Tesamorelin is a synthetic 44-amino-acid analog of growth-hormone-releasing hormone (GHRH) with a trans-3-hexenoic acid modification that resists enzymatic breakdown. It is the only GHRH peptide approved by the FDA as a finished drug product (Egrifta) and is sold here strictly as a research reagent.

GLP-3 / Retatrutide: Triple GIP/GLP-1/Glucagon Agonist Research Brief
Retatrutide (LY3437943) is a once-weekly triple hormone receptor agonist that activates GIP, GLP-1, and glucagon receptors from a single molecule. It is sometimes informally referred to as 'GLP-3' because it represents the third major generation in the GLP-class metabolic peptide lineage after semaglutide (GLP-1) and tirzepatide (GIP/GLP-1).

BPC-157 vs TB-500: Mechanism, Research Use & How They Differ
BPC-157 and TB-500 (Thymosin Beta-4 fragment) are the two most-cited peptides in tissue-repair research. They are frequently confused, often stacked, and operate through distinct mechanisms. This guide breaks down what the published literature actually says about each.

Semaglutide vs Tirzepatide: GLP-1 Mono vs Dual-Agonist Research
Semaglutide is a GLP-1 receptor agonist. Tirzepatide is a dual GLP-1/GIP agonist. The two peptides dominate metabolic-research literature, and the head-to-head SURMOUNT and SURPASS data are why the dual-agonist class has become the new benchmark.

Retatrutide vs Tirzepatide: Triple Agonist vs Dual Agonist Research
Retatrutide adds glucagon-receptor activity on top of the GLP-1/GIP dual agonism that defines tirzepatide. The Phase 2 readout (NEJM, 2023) made it the most-watched investigational peptide in metabolic research.

Ipamorelin vs CJC-1295: GHRH Analog vs GH Secretagogue Research
Ipamorelin and CJC-1295 are the two most-stacked growth-hormone peptides in research. They work on different receptors, produce complementary GH pulses, and together generate a larger response than either compound alone.

How to Reconstitute a Peptide (Step-by-Step Laboratory Reference)
Reconstitution is the process of dissolving a lyophilized (freeze-dried) peptide into sterile diluent — usually bacteriostatic water — to produce a known concentration. The math is straightforward once you separate vial size, diluent volume, and per-administration volume.

BPC-157 Dosage & Research Protocols (Laboratory Reference)
This is a laboratory-reference summary of how BPC-157 is dosed across the published preclinical literature. It is not medical or dosing advice — BPC-157 is not approved by the FDA for human use.

Reading a Peptide COA: What Purity & HPLC Numbers Actually Mean
A Certificate of Analysis (COA) is the document that proves a peptide is what the vendor says it is. A real COA is a third-party lab report — not a marketing PDF. This guide walks through every section so you can spot a legitimate document at a glance.

Peptide Blends Explained: Why GLOW, Wolverine & KLOW Combine Compounds
A peptide blend is a single lyophilized vial containing two or more synthesized peptides combined at fixed ratios. Blends are popular in laboratory tissue-repair research because they reduce reconstitution steps and lock in a consistent component ratio across study days.
