Prices captured 2026-06-27 from the live /shop page (vials, price per vial). The vendor uses GLP code names instead of the regulated drug names: GLP1-S = semaglutide, GLP2-T = tirzepatide, GLP3-R = retatrutide (inferred from the Finnrick product set and the COA-page lot codes GLP1-S-*, G2T*, etc.) — a common compliance euphemism for GLP-1 research compounds. Many SKUs are multi-peptide blends, so price-per-mg is total-peptide-per-vial and not comparable to single-compound vials. No purity figure is shown on shop listings.

Independent test results

3 independent tests tracked — labs and findings as reported. No pass/fail tally is computed.

Finnrick Analytics — community aggregate
26 samples across 5 products, tested 27 Feb 2025 – 28 Mar 2025; overall average 4.7/10. Per product: Tirzepatide Grade A (avg 7.1, 99.89%); CJC-1295 Grade C (avg 6.2, 98.23%); Retatrutide Grade D (avg 5.9, 99.81%); BPC-157 Grade E (avg 4.2 — poor score despite 99.98% purity, indicating a quantity/under-dose or batch-info problem rather than impurity); Semaglutide Grade E (avg 0.8). Across all samples ~81% confirmed the expected peptide (identity), median purity 99.5% among passing samples, and ~86% of passing samples tested at or above 98%.
Finnrick Analytics — semaglutide detail
6 semaglutide samples (28 Feb–28 Mar 2025) scored 5.0, 0.0, 0.0, 0.0, 0.0, 0.0 → Grade E (Bad). One sample reached 97.82% purity; the other five carried the warning 'Sample does not contain Semaglutide' (identity failure). Finnrick anonymizes its testing labs as Lab A / Lab B / Lab C.
Secondary synthesis (SeekPeptides / ScamAdviser) — UNVERIFIED
Secondary write-ups characterize the Finnrick semaglutide failure as at least one Coastal Peptides 'semaglutide' sample that was actually tirzepatide (a different compound). The primary Finnrick semaglutide page itself only states the samples 'do not contain Semaglutide' and does not specify tirzepatide. Surfaced for completeness; treat the tirzepatide-substitution detail as unverified.

Trustpilot (synthesis)Positive2025-2026
Predominantly positive customer reviews emphasizing fast FedEx shipping (orders 'arriving in a few days'), discreet/secure packaging, product effectiveness, and responsive support; the main recurring complaint is small vial sizes relative to promo offers.
SeekPeptides / community synthesisMixed2025-2026
Mostly positive ('highest quality', 'very reliable', 'incredibly fast' shipping, repeat buyers), but at least one buyer reported that retatrutide 'had no effect' and described 'very bad support' before switching suppliers — consistent with the Finnrick finding that purity is decent on some compounds while specific SKUs (notably semaglutide) underperform.
Peptide buyers group thread 'Has anyone used Coastal peptides?'Neutral
A public Facebook group discussion asking about experiences with Coastal Peptides exists; thread content was not directly retrievable (login-gated), so sentiment could not be synthesized. Recorded as a community touchpoint only.

UGC · disclaimedV15

3 platforms on record — scores differ by scale; read the notes

Trustpilot4.6(53)

Snippet-sourced (page 403s to direct fetch); score/count vary across captures (42–53 reviews), figure trending up; ~90% five-star per one snippet

Algorithmic 'Very Likely Safe' verdict, but flags: WHOIS owner identity hidden, low Tranco traffic rank, Domain-Validated (DV) SSL only, and a product category 'also offered often by scammers'. Not an endorsement.

Unclaimed/unverified listing (member since Mar 2026), 0 reviews, 33 products indexed; platform 'Testing Score 0/7' reflects that the vendor submitted no COA/HPLC/MS docs TO this platform — not an independent purity result.

Trustpilot profile for coastalpeptides.com shows a high score (~4.6/5) on a small, growing review base — captured figures vary across snippets (4.0/42, 4.5/51, 4.6/53), consistent with a new vendor (domain registered Jan 2024) accumulating reviews. The Trustpilot page itself returned HTTP 403 to direct fetch, so the exact live score/count is snippet-sourced and unverified; whether the profile is claimed could not be confirmed. Given the vendor's youth and small sample, a review-seeding risk cannot be excluded. Independent lab testing (Finnrick) is markedly more negative than Trustpilot sentiment, especially on semaglutide.

FAQ

CitedV31
Is Coastal Peptides legit, and what is on record?
Coastal Peptides (coastalpeptides.com) is a US-facing research-peptide retailer on a domain registered in January 2024. On record: a generally positive but small Trustpilot profile (~4.6/5), a 'Very Likely Safe' algorithmic ScamAdviser verdict that still flags a hidden WHOIS owner, and independent Finnrick lab testing that is far more mixed — an overall 4.7/10 average and a failing grade on semaglutide (five of six samples did not contain semaglutide). No FDA warning letter, BBB profile, or confirmed non-delivery scam report was found as of June 2026. PeptideCompass computes no vendor score — weigh the cited facts yourself. Research use only.
Does Coastal Peptides provide COAs / third-party testing?
The site claims every peptide gets 'independent third-party analytical testing' and publishes a Test Reports page listing ~28 products with lot numbers and certificate images. However, no testing laboratory is named anywhere on that page, and no method or numeric purity appears in the page text. Independent testing by Finnrick Analytics found high purity on several compounds (BPC-157 99.98%, tirzepatide 99.89%) but a serious identity failure on semaglutide. Research use only.
How does Coastal Peptides ship and take payment?
Shipping is FedEx-only (2-Day or Overnight), free over $250, with same-day dispatch on orders paid by 4 PM EST Monday–Saturday. Payment is by credit/debit card (Visa, Mastercard, Amex, Discover) or Cash App; no cryptocurrency or Zelle is offered on the vendor's page, and FSA/HSA cards are not accepted. Order changes or cancellations must be requested within one hour. Research use only.
Could Coastal Peptides be confused with another vendor?
Yes. Several similarly named brands exist and are distinct businesses: Coast Peptides (coastpeptides.com, a Southern Aminos brand), Treasure Coast Peptides (a separate Florida vendor), Gulf Coast Peptides, and a separate 'official' storefront at officialcoastalpeptides.com that uses the same Coastal Peptides name but lists different products and prices. Verify you are on coastalpeptides.com before ordering. Research use only.
