Who is Progression Peptides?
Progression Peptides presents itself as Progression Peptides, LLC, a supplier of research-use peptides and related compounds. Its About page describes laboratory and research purposes, not human consumption, dosing, injection or ingestion.
The merchant's Contact page lists Washington, Utah as its home base, progressionpeptides@gmail.com and (435) 680-3786. These are published contact details, not our independent verification of its legal registration, manufacturing location or support responsiveness.
The product catalog includes individual compounds, blends and laboratory supplies. GHK-Cu is our documented product example below; this review does not assess efficacy or recommend a compound for personal use.
What do Progression Peptides' COAs actually show?
Progression Peptides provides a public COA library. A certificate of analysis, or COA, reports results for a submitted sample; it is not automatically evidence for every vial currently offered.
We read the merchant-hosted GHK-Cu 50 mg certificate dated September 11, 2026. The document names Elevated Laboratories, LLC as the laboratory and Progression Peptides as the customer.
| Certificate field | Reported result |
|---|---|
| Product and stated strength | GHK-Cu, 50 mg per vial |
| Lot / task number | 2082 / EL-2026-399 |
| Sample received / test date | September 3 / September 11, 2026 |
| Measured quantity | 50.06 mg per vial |
| Purity | 99.18% |
| Single impurity / total impurities | 0.54% / 0.82% |
| Quantification method named | UHPLC-UV-PDA-QDA |
The certificate says it applies only to the referenced vial and is for research purposes. It also notes that salts and sugars may not be detected by UV and are not counted as impurities.
Those limitations matter: the reported purity is not proof of sterility, absence of endotoxins or safety for human use. We did not commission testing, authenticate the report with the named laboratory or establish that current inventory matches lot 2082.
Are the merchant's testing claims consistent?
Progression Peptides uses different testing-frequency claims on its own website. On October 23, the homepage displayed “TRIPLE-TESTED” and “2x tested”; the site footer described products as “twice-tested.”
We cannot resolve that difference from the published certificate alone. This review therefore reports the specific document's results rather than endorsing a catalog-wide number of tests, manufacturing claim or certification.
How much does Progression Peptides cost?
One GHK-Cu 50 mg vial displayed $35 before coupon, tax and shipping in our October 23, 2026 browser check. We selected the 50 mg option on the GHK-Cu product page and confirmed the same merchandise subtotal in the cart.
| Price check | Observed value |
|---|---|
| Product / quantity | GHK-Cu, 50 mg, one vial |
| Displayed previous price | $49 |
| Displayed sale price / cart merchandise subtotal | $35 |
| Checked | October 23, 2026 |
Prices can differ by selected size, promotion and time. The cart observation is not an order or a guarantee of a future price; we did not pay or submit an order.
For the separate offer details, see the Progression Peptides coupon code page. Keep the displayed merchandise price separate from any coupon saving, delivery charge and tax when comparing a total.
What are Progression Peptides' shipping and return policies?
Progression Peptides advertises free shipping at $200+ and a 2 p.m. Mountain Time cutoff for same-day dispatch on qualifying weekday orders. These are merchant-published shipping claims, not delivery times we observed or guaranteed arrival dates.
The refund and return policy says all sales are final, including ordering errors and changes of mind. It also describes a limited problem-order process:
- Report within 48 hours: Notify support if an order arrives damaged, defective or incorrect.
- Provide evidence: Include a description and clear photographs for replacement review.
- Limited refund consideration: The policy mentions merchant-error nondelivery, or cases where a replacement is impossible and the issue was reported on time.
- Restrictions: The policy excludes refunds or replacements for opened, used or unauthorized returned items.
The merchant's Terms and Conditions state that customers must be at least 21 and that Progression Peptides may refuse sales to unqualified individuals. A later paragraph in the same terms instead says a minimum age of 18; we cannot resolve that inconsistency. These are the merchant's published conditions, not our determination of eligibility.
We have not tested delivery speed, replacement handling or refund outcomes. Read the current policy before ordering rather than treating the existence of a support process as a promise of approval.
What independent customer evidence did we find?
Our October 23 searches did not locate attributable, vendor-specific Reddit reviews or usable Trustpilot customer reviews for progressionpeptides.com. The direct Trustpilot domain-profile lookup returned a page-not-found message, so we do not assign a Trustpilot score or transfer ratings from similarly named businesses.
This limited search does not prove that customer experiences or complaints do not exist. It means we cannot responsibly supply a testimonial section or characterize overall customer sentiment from the material found.
We have not purchased or received a product for this review. The cart check establishes a displayed price, not fulfilment reliability, product identity or laboratory quality.
How should researchers compare the available documentation?
Compare the evidence behind each claim, not just a purity percentage. For Progression Peptides or another supplier, the useful questions are:
- Lot match: Does the report identify the lot being supplied?
- Quantity: Does the report measure the claimed amount per vial?
- Method and scope: What did the laboratory actually measure, and what does the report exclude?
- Provenance: Who supplied the sample, and can the document be authenticated with its issuer?
- Separate assays: Are any claimed sterility or endotoxin results separately documented rather than inferred from purity?
Our peptide vendor reviews hub provides other supplier reviews for comparison. This checklist does not establish that any supplier is suitable for human use.
What is the verdict on Progression Peptides?
Progression Peptides offers inspectable product documentation and published purchasing policies, but our review cannot establish the quality of delivered products or consistent fulfilment. The strongest verified finding is access to those records, not an independent endorsement of the merchant.
- Useful for: Qualified researchers comparing published COA fields, a dated price example and order policies.
- Not evidence for: Human-use safety, treatment efficacy, reliable delivery or a blanket “legit” or “scam” verdict.
- Still unverified: Laboratory authentication, current-stock lot matching, manufacturing origin, customer-service performance and representative customer sentiment.
The merchant's terms restrict products to laboratory research and exclude human or animal use. We give no star rating or numerical trust score.
Frequently asked questions
Does Progression Peptides publish COAs?
Yes. Progression Peptides maintains a public certificate-of-analysis library. We reviewed a merchant-hosted GHK-Cu 50 mg certificate; that does not verify every product or current lot.
What did the GHK-Cu certificate report?
The September 11, 2026 document reports 50.06 mg per vial and 99.18% purity for lot 2082. The document limits its conclusions to the referenced vial, and we did not authenticate it with the named laboratory.
Are Progression Peptides purchases refundable?
The published policy generally makes sales final. Damaged, defective or incorrect orders must be reported within 48 hours for replacement review; limited refund circumstances are described in the policy.
Does Progression Peptides advertise free shipping?
The homepage advertised free shipping at $200+ when checked on October 23, 2026. We did not test delivery, and the offer is not a guaranteed arrival date.
Are Progression Peptides products intended for human use?
No. Progression Peptides describes its products as laboratory-research materials, not products for human consumption, dosing, injection or ingestion. Published purity results do not establish human-use safety.
