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

semaglutidetirzepatide

Pros

✓Offers both compounded and FDA-approved branded GLP-1s, and labels which is which on the landing page: compounded semaglutide from $149.99/mo, compounded tirzepatide from $249.99/mo, and brand-name Ozempic, Mounjaro, Wegovy, Foundayo and Zepbound from $199.99/mo (checked July 27, 2026)
✓Brand-name medication at $199.99 undercuts its own compounded tirzepatide, so the FDA-approved route is not automatically the expensive one here
✓Trustpilot rating of 4.4 across 1,034 reviews
✓This offer is restricted in only two states, Alaska and Washington - the narrowest exclusion list of any provider we have reviewed
✓Substantial free tooling and educational content: BMI and TDEE calculators, a semaglutide versus tirzepatide comparison, and guides on what GLP-1s actually do
✓Testosterone, oxytocin and weight-loss protocols under one roof if you want hormone and metabolic care from the same clinic
✓The body-fat chart carries a 'Results may vary' disclaimer rather than presenting the figure as a promise

Cons

✗The headline result claim is '↓28%' body fat, sourced only to 'Averages based on real results from Maximus clients'. That data is not published, and body fat is a different measure from the body-weight percentages every other provider quotes - the two are easy to confuse when comparing
✗We could not find an explicit 'not FDA-approved' disclosure for the compounded products. The category is labelled 'Compounded' and the other is labelled 'FDA-approved', but the plain statement most competitors make is missing
✗No refund or cancellation policy is published - only a privacy policy and terms of use
✗A statistic on the oxytocin product renders as '↑ 0 %of participants reported', so at least one clinical figure on the page is broken
✗'Starting at' pricing on all three categories, with no indication of what plan length unlocks the lowest rate
✗GLP-1 sits alongside testosterone and mood products in a men's-focused brand, so the weight-loss programme is one line among several
✗No published phone number or support hours on the landing page
