Peptide Library
Each compound in the PX-Labs catalog is synthesized to pharmaceutical-grade specification, lyophilized under sterile conditions, and verified for identity, purity, and mass by independent third-party HPLC and mass spectrometry.
For laboratory & research use only — not for human consumption.
GLP-1 / GIP / Glucagon Tri-Agonist
A triple-receptor agonist targeting GLP-1, GIP, and glucagon pathways simultaneously, studied in clinical trials for metabolic and weight-management research.
Body Protection Compound
A 15-amino-acid synthetic peptide derived from a gastric protein, studied for its role in cellular regeneration and tissue-repair signaling pathways.
Thymosin Beta-4 Fragment
A synthetic fragment of the naturally occurring Thymosin Beta-4 protein, investigated for actin regulation and cellular migration in vitro.
Copper-Binding Tripeptide
A naturally occurring copper-binding tripeptide (Gly-His-Lys-Cu), studied for collagen synthesis signaling and dermal fibroblast activity.
Intranasal Nootropic — NEW
A synthetic heptapeptide based on the immunomodulator tuftsin, studied for anxiolytic signaling and BDNF expression. Pre-formulated 10mg/5ml nasal spray.
Intranasal Nootropic — NEW
A synthetic ACTH (4-10) analog studied for neurotrophic and cognitive-pathway research. Pre-formulated 10mg/5ml metered nasal spray.

The PX-Labs Standard
PX-Labs was founded by a team obsessed with one thing: consistency. In an industry filled with unverified claims and inconsistent batches, we built a supply chain where every milligram is accounted for — from raw amino acid to lyophilized vial.
Every batch is independently tested by a third-party lab using HPLC and mass spectrometry. Domestic and international orders ship with full tracking.
Research Journal
Curated literature reviews and mechanism-of-action breakdowns for every compound in the catalog — written for researchers, in language researchers actually use.
Sikiric et al. review BPC-157's cytoprotective effects, angiogenic signaling, and tissue-repair pathways across multiple in-vivo models.
Jastreboff et al. report dose-dependent body-weight reductions with the GLP-1/GIP/glucagon tri-agonist retatrutide over 48 weeks.
