Medications

semaglutidetirzepatide

Pros

✓Tiered pricing is published on the product pages: the GLP-1 + B12 program is $149/month at Level 1 ($447 for a 10-12 week supply) and $139/month at Level 2 ($834), with tirzepatide at $149 to start then $249/month billed quarterly (checked July 27, 2026)
✓Free physician consultation and free shipping are included rather than charged separately
✓A price-match guarantee is offered against competitors
✓Compounded semaglutide is paired with B12 in a single injection, which some patients prefer to two separate shots
✓Comprehensive bloodwork is available, which is more than most GLP-1 sellers offer
✓Unlimited provider access is advertised with the plan
✓One of the broader catalogues in the category if you want hormone, sexual health or longevity care from the same clinic

Cons

✗All sales are final once medication is received - PeterMD will not refund or accept returns 'regardless of whether the product remains unused'
✗Damaged or defective items must be reported with a photo within 24 hours of delivery, and the policy states that later requests 'will not be honored'
✗An exit popup pressures an HCG add-on with manufactured scarcity: 'This is the last time you'll see $301... $301 today. $412 if you add it later'
✗The discount maths on the GLP-1 page does not hold up. A '3-Month Plan' shown as 'Regular price: $358.00, Today: $315.00' is labelled '-40%'. That is a 12% reduction, not 40%
✗The same $315 figure appears as PeterMD's own discounted price and, elsewhere on the page, as what 'Others' charge in a '3.8x More Affordable' comparison
✗Tirzepatide is described as 'Clinically proven' although the product sold is a compounded preparation, which has not been through the trials that phrase refers to
✗'The Largest Online Healthcare Clinic in North America' appears in the page title with nothing to support it
✗This offer is not available in Alabama, Arkansas, California, Idaho, Iowa, Kentucky, Louisiana, Massachusetts, Michigan, North Carolina, South Carolina or Texas - twelve states including the two largest

Medications

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
