Pros
- ✓The quality documentation is genuinely thorough for this category: HPLC and mass spectrometry on every lot, a signed certificate of purity shipped with every order, and a public lab-report library you can read before buying
- ✓Endotoxin testing (LAL assay) and microbial screening to USP standards on every batch before release
- ✓Full batch traceability - each vial traced to its production lot, raw materials and test results
- ✓States an average of 99.3% HPLC purity across all batches and publishes the underlying numbers rather than only the claim
- ✓Partner labs described as GMP-aligned, with documented SOPs and controlled environments
- ✓Pricing is straightforward and published: individual peptides run roughly $59.99 to $159.99, with free shipping over $150 (checked July 28, 2026)
- ✓The research-use-only status is disclosed up front behind an acknowledgement gate, not buried in a footer after checkout
- ✓A published phone number and a catalogue organised into peptides, blends, sprays and capsules, with a reference database
Cons
- ✗This is not a treatment and cannot lawfully be sold as one. Everything here is labelled for research use only and explicitly not for human consumption. If you are reading this site to find help with weight loss, this is not an option - it is laboratory material
- ✗There is no clinician at any point. Nobody takes a history, nobody checks your contraindications, nobody sets a dose and nobody monitors you. The safety net that every licensed provider on this site provides simply does not exist here
- ✗A certificate of analysis tells you what is in the vial. It tells you nothing about whether the contents are safe for you, what dose is appropriate, or how it interacts with your medications
- ✗Products arrive as lyophilised powder requiring reconstitution, and bacteriostatic water, syringes and other supplies are not included - so self-administration would also mean improvising sterile technique
- ✗Peptides such as BPC-157 and TB-500 appear on the FDA's list of substances that raise significant safety concerns for compounding, and have little or no published human trial evidence
- ✗There is no prescription, no pharmacy oversight and no adverse-event reporting pathway. If something goes wrong there is no clinical record and no provider to call
- ✗No Trustpilot or BBB record exists, so there is no independent consumer feedback of any kind
- ✗Our rating reflects suitability for someone seeking treatment, which is what this site compares. As a laboratory supplier the documentation is strong; as a route to a GLP-1 or peptide for your own health it is the wrong door, and a licensed provider is the right one

Pros
- ✓The programme lives on as WeightWatchers Clinic, which is reviewed separately on this site
- ✓Its original model - GLP-1 medication paired with registered dietitian support and behaviour change - carried over into the WeightWatchers offering

Cons
- ✗You cannot sign up for Sequence. It no longer exists as a standalone service and both former domains are offline - go to WeightWatchers Clinic instead
- ✗Historic pricing and plan details from the Sequence era no longer apply, so any figures you find elsewhere for it are out of date
- ✗Because the brand was absorbed, older reviews and testimonials for Sequence describe a service that has since changed hands and structure
