What to expect when you sign up with StackLab
We walked StackLab’s public signup flow in November 2026 to document the process (the steps, pricing transparency, and what’s required) before you commit. (We don’t create accounts, enter medical information, or check out; this is the observable funnel, not a prescribing outcome.)
- 1'See if I'm eligible' or a treatment's 'Start' button opens a nine-step assessment whose first question asks whether you already take a GLP-1
- 2StackLab says the assessment takes about 3 minutes, then you pick a plan length and accept the terms before checkout
- 3You pay at checkout; a licensed clinician reviews your answers within 24 hours and you're refunded in full if not prescribed
- 4If prescribed, the medication is made to order and ships free in 2 to 3 days, with refills every 28 days
- The homepage shows 'from' prices that are the 12-month plan rate and says month to month starts from $119
- The plan step offers month-to-month, 3, 6 and 12-month plans, all priced per 28-day supply
- Multi-month plans are charged once up front and renew at the end of the term
- The terms name OpenLoop-affiliated medical groups as the prescribers, and the FAQ names three partner pharmacies with addresses
- Support is by email and in-account messaging; no phone number is listed

What we like
- Low compounded prices: semaglutide from $79 and tirzepatide from $139 per 28 days on the 12-month plan
- Same price at every dose, with no membership fee
- Price includes the prescription, medication, supplies, shipping, monthly check-ins and messaging
- Full refund if a clinician doesn't prescribe
- LegitScript seal served from LegitScript's own site
- Names its clinicians' affiliated medical groups (OpenLoop) and its partner pharmacies, with addresses

Watch-outs
- The month-to-month plan bills every 28 days, so a year means 13 charges, not 12
- The lowest prices need up to $1,807 paid up front for a year of tirzepatide
- You pay at checkout, before a clinician reviews your answers
- No refund for the current month on the month-to-month plan once it has been charged
- Cancel at least 72 hours before your next billing date or you're charged for another cycle
- No phone number is published, even though the site invites you to call
- Disputes go to binding individual arbitration
Is StackLab worth it?
StackLab's whole pitch comes down to this: low compounded GLP-1 prices, flat at every dose, if you're comfortable with 28-day billing or prepaying. It runs $119/month (per 4 weeks) at every dose; there's no clean category median to weigh that against, but it's a published number rather than one you find out only after signing up. Its flat, all-dose pricing helps anyone worried about cost climbing as they titrate up.
StackLab is LegitScript-certified. It also charges the same price at every dose and charges no membership fee.
How much StackLab costs
Compounded semaglutide runs $79–$119/month depending on plan, the low end a 12-month plan rate, and compounded tirzepatide runs $139–$159/month depending on plan, the low end a 12-month plan rate.
Because StackLab's headline figure is listed as “per 4 weeks”, we don't set it against the roughly $179 market median for this category. That median is each program's lowest listed ongoing monthly price for compounded semaglutide, so compare StackLab with the month-to-month prices of the alternatives below instead.
Live Vital (about $130/month) is one of the closest alternatives to weigh StackLab against.
Medications: what StackLab prescribes
StackLab prescribes semaglutide (the active drug in Wegovy and Ozempic) and tirzepatide (the active drug in Zepbound and Mounjaro), the two most-studied weight-loss molecules on the market today. The medication is compounded at a licensed pharmacy rather than sold as a brand pen, which is what keeps the price down. The trade-off is the one every compounded provider shares: compounded drugs aren't FDA-approved as finished products.
Who StackLab is best for, and who should skip it
A good fit if you…
- live anywhere in the US and want the certainty that your state is already covered.
Look elsewhere if you…
- specifically want an FDA-approved brand-name pen instead of a compounded formulation, which this provider doesn't fill.
- need to bill insurance, since like most of this market it's cash-pay with no claims filed on your behalf.
Trust, safety, and medical oversight
StackLab treats patients in all 50 states, and we found no FDA warning letter on file for it. As with any compounded program, the most important step you can take is confirming which licensed pharmacy fills your prescription and what's in the formulation, and we explain how in our scoring methodology.
Bottom line
StackLab is a reasonable telehealth GLP-1 option; weigh its pricing and coverage against the alternatives below before deciding.
