Medications

semaglutidetirzepatideliraglutide

Pros

✓A published, all-in price for the compounded semaglutide programme: $250.00 with home delivery included
✓Brand-name options are listed alongside compounded ones - Ozempic, Mounjaro, Saxenda, Wegovy, Zepbound and Contrave all appear in the medication catalogue
✓A published phone number, (214) 466-6618, plus email and text support - more contactable than most telehealth weight-loss services
✓Coverage across all 50 states plus the District of Columbia
✓Long service hours: Monday to Friday 5am to midnight CT, weekends 6am to 1am CT
✓No appointment needed - visits happen online when you start them
✓A "Subscribe & Save" programme brings general visits down to $12, useful if you use the service for more than weight loss
✓An RX Savings Card is offered to reduce prescription costs
✓Every programme includes a licensed provider visit that reviews your history and confirms the medication and dose

Cons

✗The $250 compounded semaglutide price is presented on the medication page, but the weight-loss programme pages do not carry a comparable published price for every option
✗Compounded medication is not FDA-approved and has not been reviewed by the FDA for safety, quality or efficacy
✗No refund or cancellation policy is published on the weight-loss pages
✗Insurance is not addressed on the weight-loss pages - this reads as a cash-pay service
✗Patient testimonials are duplicated verbatim across the page, which undermines their value as evidence
✗It is a broad urgent-care telehealth service first and a weight-loss provider second, so there is no dedicated coaching or nutrition programme
✗HSA/FSA acceptance is not stated

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
