Medications

semaglutidetirzepatide

Pros

✓Both price ladders are published in full and the arithmetic is correct at every tier. Semaglutide runs $249 for one month, $217/mo over three ($650), $175/mo over six ($1,050) and $158/mo over twelve ($1,900), checked July 27, 2026
✓Tirzepatide is laid out the same way: $297 monthly, $267/mo over three ($800), $217/mo over six ($1,299) and $167/mo over twelve ($1,999)
✓Every advertised saving checks out - the 13%, 30%, 37%, 10%, 27% and 44% figures all match the underlying numbers
✓One price across all doses, from 0.25mg to 2.4mg semaglutide and 2.5mg to 15mg tirzepatide, so titrating up never costs more
✓Possible side effects are listed openly on the product page - nausea, injection site reactions, decreased appetite and gastrointestinal discomfort - with a note that most are mild and temporary
✓Both injectable and oral formats are offered at the same published prices
✓Medication, provider review, personalised dosing and ongoing support are all included in the price, with free shipping and cancel-anytime terms

Cons

✗We could not find an explicit statement that the compounded medications are not FDA-approved. The site explains what compounding is but omits the disclosure nearly every competitor makes
✗Trustpilot has exactly one review of this domain, so there is effectively no independent evidence about the service against a claim of 2,400+ patients
✗Tirzepatide is billed as the 'Most powerful GLP-1 medication available' - a superiority claim made about a compounded preparation that has not been trialled against anything
✗The 'up to 15% of their body weight in a year' figure is presented as what TMates has seen in its own patients, with no published data behind it
✗The lowest advertised rates require paying for a full year upfront - $1,900 for semaglutide or $1,999 for tirzepatide
✗The site is behind bot protection and will not load without JavaScript, so pricing is invisible to anyone browsing with scripts disabled
✗No published customer phone number, support email or support hours
✗No BBB profile or complaint record to check

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
