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
- ✓Among the lowest advertised prices in the category: compounded semaglutide from $119/month and tirzepatide from $185/month (checked July 27, 2026)
- ✓One price at every dosage, so titrating up does not increase what you pay
- ✓Free shipping and free health coaching are included, with no separate membership fee
- ✓Same-day approval is offered and no video call is required, which suits people who cannot take time out for an appointment
- ✓Publishes a phone number, an email address and the legal entity behind the brand
- ✓The compounded explanation distinguishes 'not FDA-approved as finished products' from the ingredients and conditions used, which is more accurate than the blanket claims some rivals make
- ✓A comparison calculator and a public price comparison table let you check the maths before signing up
- ✓Cancellation can be done from your own account by cancelling the prescription or deleting the account, rather than only by emailing support
Cons
- ✗The homepage advertises 'One price · All dosages · No subscriptions', but the terms contain a 'Refund, Shipping, Cancellation Policy' describing how cancelling will 'stop any future subscription renewals or charges'. Those two statements cannot both be right
- ✗A third price appears in Oak's own comparison table, which lists 'Oak $167/mo' against headline rates of $119 and $185. The table never explains which product $167 refers to
- ✗'Same Active Ingredient' is used as a feature row comparing Oak to brand-name drugs. That is the precise claim the FDA cited in a February 2026 warning letter to another telehealth firm, on the basis that it implies FDA approval the compounded product does not have
- ✗Promotions stack confusingly - a 'SUMMER SALE - Save up to 60% vs. retail pricing' banner sits alongside a separate '$200 off new patient offer' with no terms for either
- ✗Trustpilot carries only 53 reviews, far too few to corroborate the '10,000+ Satisfied Patients' claim
- ✗There is no dedicated refund policy page; refund terms are buried inside the general Terms of Use
- ✗The Terms of Use include a dispute resolution and arbitration agreement
- ✗'Up to 50% cheaper than competitors' is asserted repeatedly in a scrolling banner without naming the competitors or the basis for the figure
