Signaling Peptides
BPC-157, TB-500, KPV, Semax, Epitalon, GHK-Cu, AOD 9604, SS-31 — single-compound research peptides.
Coast Star Labs supplies research-use-only peptide compounds for laboratory and in-vitro investigation, each batch verified with an independent Certificate of Analysis.
The same documented sequence runs for every lot before it's listed as in stock — nothing ships without it.
Catalog is sourced from one manufacturer, tracked by product and lot — no mixed or unverified sourcing.
HPLC purity trace, mass identification, and endotoxin threshold screening on every lot.
Manufacturer's COA is linked in full, unedited, before a compound is marked in stock.
Packed and shipped with lot documentation available on request.
Every listing is documented the same way, whether it's a single compound or a fixed-ratio formulation.
BPC-157, TB-500, KPV, Semax, Epitalon, GHK-Cu, AOD 9604, SS-31 — single-compound research peptides.
Tesamorelin, Sermorelin, Ipamorelin, CJC-1295 (No DAC), MOTS-c for pulsatile-secretion research.
NAD+ and GLP-R3 (Retatrutide) for incretin-pathway and cellular-energy research.
GLOW, PULSE, ELEVATE, WOLVERINE, KLOW — fixed-ratio, pre-set multi-peptide vials.
Manufacturer-issued certificates linked per product — purity, identity, and endotoxin results.
Bulk and institutional ordering with dedicated invoicing and documentation support.
Every step is documented, so what you receive matches what was tested — no gaps between the certificate and the vial.
Order confirmation sent with expected dispatch window.
Accession number confirmed against current inventory before pick.
Tracking issued the same day the order ships.
Your order's COA stays linked to your account for reference.
Select any combination of catalog items and add them to your order in one pass — a self-service tool for faster checkout, not a recommendation of what to select.
Certificates are produced using HPLC with UV detection coupled to mass spectrometry, with duplicate-replicate endotoxin screening performed under USP <85> guidance. Results are reported by the testing lab, not summarized or reworded by us.
Coast Star Labs performs sourcing, documentation, and fulfillment. Independent laboratory testing is performed by our manufacturer's third-party lab partner.
A new company, run the way a research supplier should be from day one.
Every compound traces back to one manufacturer and one lot — not a mix of unverified suppliers rebranded under one label.
A lot isn't marked in stock until its Certificate of Analysis is published. No exceptions, no "testing pending" sales.
Order and documentation questions go to a real person, not a ticket queue — see the contact page for current response times.
Coast Star Labs was founded to bring documented, lab-verified sourcing to the research peptide market — every compound traceable to a manufacturer, a lot, and a certificate, not just a listing.
As a new company, orders and documentation requests are currently handled directly by our founder — meaning consistent standards and someone accountable for the answer, every time.
Feedback on service, documentation, and shipping — not on use of any compound.
"Asked for the lot's COA before ordering and had it within the hour. That level of documentation is rare in this space — it's the reason we keep coming back."
"Order shipped fast and the documentation matched exactly what was on the site. Only note — packaging could use a bit more padding for glass vials."
"Emailed a wholesale question and got a direct, specific answer same day — not a form letter."
Our team responds to general account, wholesale, and documentation inquiries. This channel does not provide guidance on individual use of any compound.
