Online prescribing of controlled substances runs on a temporary DEA rule that expires December 31, 2026. It covers testosterone and stimulants. It does not cover GLP-1s, which are not on the DEA's schedules.

03 / What we recommend
We include products and services we think are useful. If you buy through links on this page, we may earn a commission. Here is how we pick.
At-home lab tests
4.0
Everlywell
Best for readers who want a baseline or a between-visit check on a specific marker and will take the result to a clinician.
Everlywell is a reasonable way to get a finger-prick A1C, lipid or testosterone number without a clinic visit, at $49 to $149 a test, with CLIA-lab processing and physician review. It is a screening tool, not a diagnosis, and it is not sold in New York.
HbA1c $49; cholesterol and lipids $49; heart health panel $99
Telehealth / primary care
4.0
Sesame
Best for uninsured or high-deductible readers who want an upfront price for a visit, or a lower-fee brand-only GLP-1 program.
Sesame is the honest budget option: transparent per-visit cash prices, clinicians in every state, and a weight-loss program that sells brand-name GLP-1s only. It does not bill insurance, so insured readers pay out of pocket for the visit.
Telehealth visits from $34; weight-loss program $99/mo or $59/mo annual
Weight management / GLP-1
3.3
Trimi
Best for cash payers set on a compounded GLP-1 who will prepay a longer plan and accept that these are not FDA-approved products.
Trimi undercuts every compounded program we checked ($99 to $175 a month for semaglutide) and names its prescriber network and pharmacies. Its own terms never name a legal entity, and one cited pharmacy license resolves to a different company name. Good price, read the fine print.
Compounded semaglutide from $99/mo on a 12-month prepay; $175 month to month

05 / How we work
01
Every number has a source and a date
A reference range or screening row cannot be saved without the primary document that sets it and that document's own date.
See the library →02
Services are checked before they appear
Checked against FDA warning letters and import alerts, state actions and the terms of sale, on a recorded date. No check, no link.
Read the record →03
Compounded products are labeled, always
A seller of compounded medicines carries a notice above every button, and never appears beside enforcement coverage.
Our partner rule →04
We say what we do not know
"Unverified" and "the source publishes no total" appear on the page rather than a confident wrong figure.
How we work →Every Tuesday: one biomarker explained, what changed in GLP-1 and lab pricing, and one guide worth your time. Every number sourced and dated. Free, no spam.
We'll never share your email. We never sell your data.
