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

$99
Medications
semaglutidetirzepatide

Pros

  • Offers FDA-approved brand-name options alongside compounded ones: the Wegovy pill, Wegovy injection and Zepbound injection are all listed at '$99 membership + medication cost'
  • Trustpilot rating of 4.4 from over 14,000 reviews, a far larger and better sample than most competitors in this category
  • Free dietitian visits and care coaching are advertised as included, and the program is listed as HSA/FSA eligible
  • Both injectable and daily dissolvable tablet formats are offered
  • Clinical services run through OpenLoop Health, an established nationwide clinician network
  • Full refund if a provider disqualifies you, and a full refund if you cancel within the first 72 hours before receiving any services
  • The terms state plainly that compounded GLP-1s are 'not FDA-approved or evaluated for safety, efficacy, or quality'
  • Published cancellation route by email or in-portal chat, with a named support address

Cons

  • The FDA issued MEDVi a warning letter on February 20, 2026 for misbranding its compounded semaglutide and tirzepatide, including for labelling vials as though MEDVi compounded them when it does not, and for 'same active ingredient as Wegovy' style claims the agency said imply FDA approval. This is the most serious regulatory finding against any provider on this site
  • We could not verify what the compounded plans actually cost. The affiliate landing page renders its own price placeholders unsubstituted - the page literally reads 'Only ${seminject_sale_price}' and 'Starting at ${semtab_sale_price}' in eight places
  • The only price that does render, $99, is a membership fee that explicitly excludes the medication cost, so it is not comparable to the all-in prices quoted by other providers
  • The same page claims 'No membership or hidden fees!' while listing '$99 Membership + Medication Cost' for the brand-name options a few lines below
  • Patient counts contradict each other on one page: 'Join 500,000+ MEDVi patients' at the top, '10,000+ Patients Agree' further down
  • The customer testimonials are word-for-word identical to those published on TrimRx's landing page under the label 'Verified TrimRX Customer', so at least one set is not what it claims to be
  • Monthly subscribers get no refund for the month in which they cancel or for any prior month - the policy states this in capitals
  • The user agreement imposes mandatory arbitration and waives class action and jury trial rights
  • Cancellation must reach the company at least 72 hours before the next billing date or the next charge still goes through
