GLP-1 peptidesBPC-157TB-500NAD+

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

Medications

continuous glucose monitoring

Pros

✓A genuinely different approach: a continuous glucose monitor plus an app that tells you how your own body responds to specific foods, rather than a prescription subscription
✓Published plan pricing: $127/month on the longest plan, $150/month on the mid plan and $225/month on the shortest, each discounted from a higher list price
✓Two CGM sensors per month are included in every plan
✓HSA/FSA eligible, which matters at these prices
✓Registered dietitian support is included, with in-app chat and the option of a face-to-face session
✓A 30-day results guarantee: if you do not learn something new about how your body loses weight, a senior Signos coach audits your data free, described as a $250 value
✓One membership covers the sensors, the app, the coaching and the behaviour-change programme instead of stacking separate subscriptions
✓It pairs sensibly with a GLP-1 rather than competing with one, and the company states medication costs are included in the Signos programme where applicable
✓Stress and sleep tracking are built in alongside glucose

Cons

✗This is not a GLP-1 prescribing service in the way the rest of this site is. If you came here for a semaglutide prescription, Signos is a different kind of product
✗The cheapest per-month rate requires the longest commitment, and six-month plans ship in three-month bundles
✗CGM-guided eating for weight loss in people without diabetes has far weaker evidence behind it than GLP-1 medication
✗HSA/FSA eligibility is qualified - "Possibly, but it depends on your HSA/FSA provider" - and Signos states it is not responsible for reimbursement, with the cancellation policy still applying if your provider refuses
✗The results guarantee pays out in a free data audit, not money back
✗Outcome claims reflect individual Signos patient experiences rather than published clinical studies, which the company discloses
✗Not suitable if you are on insulin without speaking to your own clinician first, which the signup flow asks you to confirm
