PEARL

PEARL (pearlgpo.com) is a research compound supplier with over 34 active listings on Peptides.SO, operating under what appears to be a group purchasing organization (GPO) model — the "GPO" designation in the domain suggests procurement coordination for research compound buyers who aggregate purchasing to achieve favorable unit economics. The catalog spans GLP receptor agonist research compounds, tissue healing peptides, immune biology agents, anti-aging compounds, cognitive peptides, and growth hormone-axis compounds.

The GLP receptor research compound segment is a core catalog pillar. Cagrilintide 10mg (amylin receptor agonist studied in GLP-1 combination therapy research) is listed prominently. GLP-1/GIP/Glucagon triple-agonist vials are listed — aligning with the Retatrutide (GLP-3) pharmacology of simultaneous three-receptor engagement. Tirzepatide (Tirz, dual GLP-1R/GIPR agonist) is listed in GLP agonist formats. Semaglutide (GLP-1R agonist) in 10mg 10-vial packs supports both single-experiment and bulk research supply. The CagriSema (Cagrilintide/Semaglutide) combination vial represents the amylin/GLP-1 dual-agonist research compound class.

The tissue healing and repair segment features BPC-157, TB-500 (Thymosin Beta-4), KLOW 80mg (BPC-157/TB-500/KPV), KPV (an anti-inflammatory tripeptide derived from alpha-MSH), the Wolverine Stack (BPC-157/TB-500 combination), and ARA-290. ARA-290 (Cibinetide) is a specialty listing — a peptide derived from the erythropoietin spiral B helix, studied for tissue protection, anti-inflammatory signaling via the innate repair receptor (IRR), and neuropathic pain model research.

Immune biology coverage includes LL-37 (10mg) — a human cathelicidin-derived antimicrobial peptide studied for its antibacterial, antiviral, anti-inflammatory, and immune cell activation properties. LL-37 is a research compound of high interest in innate immunity, mucosal defense, and inflammatory disease biology.

Pearl's catalog carries premium-tier pricing on most single-compound vials: KLOW Blend at $1.88–$2.06/mg (80mg), Pinealon at $3.75/mg (20mg), Oxytocin at $5.80/mg (10mg), Melanotan I at $6.00/mg (10mg), Thymosin Alpha-1 at $8.00/mg (10mg), LL-37 and VIP at $11.00/mg (10mg each), DSIP at $18.00/mg (5mg), and Tirzepatide at $18.00/mg (10mg). These prices are at or above the upper range for these compounds among peers surveyed.

The FIT Stack (CJC-1295/Ipamorelin combination) covers growth hormone-axis biology research. Tesamorelin supports GHRH analog research. VIP (Vasoactive Intestinal Peptide) covers autonomic nervous system and anti-inflammatory signaling research. DSIP 5mg is listed for sleep and circadian peptide biology research. Epitalon covers longevity research. AOD-9604 covers fat metabolism research. All PEARL products are sold for laboratory and in-vitro research purposes only.
