Reference peptides,
made under California sun.
Most orders ship the next business day after on-chain payment confirmation — cold-packed and HPLC-verified by an independent lab. The Certificate of Analysis is posted before the vial ships — public and free to inspect.
For in-vitro laboratory research use only — not for human consumption.

Most-referenced research peptides,
all 6 in stock.
BPC-157Peptide fragment
Synthetic pentadecapeptide corresponding to a fragment of human gastric juice protein. Studied in vitro in cell-migration and angiogenesis assay research.
TB-500 (Thymosin β-4 fragment)Peptide fragment
Synthetic peptide corresponding to an active fragment of Thymosin β-4; used as a reference peptide in cytoskeletal-research assays.
GHK-Cu (glycyl-L-histidyl-L-lysine : Cu²⁺)Matrix peptide
Copper(II)-binding tripeptide (GHK) used as a reference compound in extracellular-matrix and metalloprotein research.
IpamorelinReceptor ligand
Synthetic pentapeptide agonist of the ghrelin/growth-hormone-secretagogue receptor (GHSR); reference ligand for in-vitro receptor-binding research.
CJC-1295 (no DAC)Receptor ligand
Synthetic 29-amino-acid GHRH analog (Mod GRF 1-29); reference standard for in-vitro GHRH-receptor binding studies.
TesamorelinReceptor ligand
Synthetic stabilized GHRH analog; reference peptide for GHRH-receptor binding research.
Synthesized, tested, and shipped from one block in Los Angeles.
No anonymous distributors, no overseas relays. Our peptides come off the column, go straight to HPLC, and into the freezer — all within a single facility 30 minutes from LAX. Most confirmed orders ship the next business day, cold-packed for the climate.
California.
Every batch tested. Every COA public.
We post the Certificate of Analysis to the public web before the first vial of that batch leaves our door. Lot numbers stay publicly searchable. No backdating, no edits.
Each batch sent to an independent US analytical lab. We do not run our own purity testing.
PDF + JSON for each tested lot, searchable by batch code at lapeptidelabs.com/coa.
Internal temperature logs preserved for reagent stability. Cold-pack proof in every box.
Kinetic chromogenic LAL, reported on the COA so researchers can screen for endotoxin interference in cell-based assays. Not a sterility, pyrogen-free, or injectable-grade certification.
