StackLab is a telehealth platform for compounded semaglutide and tirzepatide, including lower-dose microdose plans, prescribed by clinicians from OpenLoop Health's affiliated medical groups and filled by three named compounding pharmacies. Month to month, semaglutide is $119 and tirzepatide $159, charged every 28 days at every dose; its lowest advertised rates need a 12-month plan paid up front. You pay at checkout before a clinician reviews you and get a full refund if not prescribed.

Is StackLab legit?

Yes. StackLab is a real, operating US company, and we found no FDA warning letters issued to it. We rate it 9.3/10 overall, across six areas from price to trust and safety. Legitimate is not the same as right for you, though: that part is a decision for you and a licensed clinician.

Is there a StackLab promo or coupon code?

We know of no promo or coupon code for StackLab. Its listed price is $119 a month. Coupon sites advertising "StackLab discount codes" are not a source we can vouch for, and any genuine offer shows at checkout without a code.

How StackLab scores

Six columns, each one computed from something StackLab has published rather than from an opinion we formed: what it charges, which molecules it will dispense, what its record shows, and what the monthly figure actually buys. Where a seller keeps something back, such as its price or its pharmacy, the score reflects it. Every seller we review goes through the same six columns.

What signing up with StackLab involves

What to expect on the way to a prescription: where the price appears, who fills the medication, and what the monthly price covers. It is not medical advice, and a clinician makes the prescribing decision.

  1. 1StackLab shows a price on its own site before asking anything about you, so you can compare it with other sellers before you start a questionnaire.
  2. 2StackLab names 3 pharmacies that fill its prescriptions, including Red Rock Compounding Pharmacy, which most sellers do not do.
  3. 3The monthly price includes the medication, clinician visits, shipping, lab work and coaching.
Price shown before you start
  • Lowest ongoing monthly price: semaglutide $119, tirzepatide $129. That leaves out membership fees, first-month rates and insurance copays.
  • StackLab serves all 50 states and DC.
  • The medication is compounded, so it is not an FDA-approved product and has not been reviewed by the agency for safety, effectiveness or manufacturing quality.

In its favor

  • Semaglutide costs $119 a month, 40% below the $199 median for compounded semaglutide across the sellers we compare
  • Tirzepatide costs $159 a month, 41% below the $269 median for compounded tirzepatide across the sellers we compare
  • Shows its price before the medical questionnaire, so you can compare it without handing over health information
  • The monthly price stays the same as your dose goes up
  • The monthly price includes the medication, clinician visits, shipping, lab work and coaching
  • Serves all 50 states and DC
  • Names 3 pharmacies that fill its prescriptions, which most sellers do not
  • We found no FDA warning letters issued to StackLab

Against it

  • Its semaglutide and tirzepatide are compounded rather than FDA-approved, so they have not been reviewed by the agency for safety, effectiveness or manufacturing quality

What StackLab charges

The standing price at StackLab is $119/month, unchanged as the dose goes up. Flat dose pricing matters more than it sounds: on a tiered plan the bill grows with the dose, so the figure that got you to sign up is not the one you end up paying.

  • Compounded semaglutide (injection): $119/month
  • Compounded tirzepatide (injection): $159/month
  • Compounded semaglutide (microdose injection): $129/month
  • Compounded tirzepatide (microdose injection): $129/month

For compounded tirzepatide, the median across the sellers we compare is $269/month, so StackLab's $159 is genuinely below the middle, not just advertised that way. Before you pay, compare StackLab's cancellation terms with other sellers' cancellation and refund policies. Across the compounded market the dearest tenth of sellers charges about three times what the cheapest tenth does; how much GLP-1 prices actually vary explains the spread.

bmiMD, at about $129/month, is the closest like-for-like alternative we review.

What StackLab dispenses

StackLab prescribes semaglutide (approved as Wegovy and Ozempic) and tirzepatide (approved as Zepbound and Mounjaro). Between them these are the two best-evidenced weight-loss molecules currently on the market. What arrives is compounded at a licensed pharmacy, not an approved pen. That is the reason it costs less, and the reason the finished preparation carries no FDA review behind it. The molecule can be the one in Ozempic and Wegovy; what differs is the formulation, the concentration and the dose ladder. StackLab also lists a microdose plan, and the published evidence on GLP-1 microdosing is letters and commentary rather than trials.

Safety and disclosure

StackLab tells you its price before you start the medical questionnaire, that it treats patients in all 50 states, and the pharmacy that fills its prescriptions. It also offers coaching as part of the plan. We found no FDA warning letters issued to StackLab. Because the medication is compounded, the named pharmacy is the detail that matters most: its license is the one you can look up. The FDA's warning signs for online medicine sellers are a quick check to run on any seller before you pay. How we weigh oversight, disclosure and price is set out in our scoring methodology.

Who should look elsewhere

  • You want the FDA-approved pen specifically. Everything listed here is compounded.
  • You need insurance to cover the cost. Check whether StackLab bills your plan before you start.

It fits if

  • the lowest standing monthly cost is what you are solving for
  • you want the price to stop moving as your dose climbs
  • you want coaching bundled in rather than billed on top
  • you need access wherever you live

Our read

StackLab competes on price without an obvious sacrifice elsewhere: $159/month for compounded tirzepatide, no FDA warning letters, and wide state coverage.

The Bottom Line

StackLab scores highest on the clinical side (which drugs it prescribes and how it doses) and lowest on ease of signing up. It charges from $119 a month; its compounded tirzepatide, at $159, is 41% below the $269 median among the sellers we compare.

Where StackLab is the wrong choice

No seller suits every reader, and pretending otherwise is the easiest way to sell one. On these two counts, another seller does better.

  • If you need the FDA-approved pen rather than a compounded vial, consider WellMedRx.
  • If the standing monthly cost is what decides it, consider Collective (from $59/mo + membership).

If none of these fits, our guide to alternatives to StackLab sets more sellers in the same category beside StackLab on price, states and what the price includes.

Frequently Asked Questions

StackLab is a telehealth platform for compounded semaglutide and tirzepatide, including lower-dose microdose plans, prescribed by clinicians from OpenLoop Health's affiliated medical groups and filled by three named compounding pharmacies. Month to month, semaglutide is $119 and tirzepatide $159, charged every 28 days at every dose; its lowest advertised rates need a 12-month plan paid up front. You pay at checkout before a clinician reviews you and get a full refund if not prescribed. We rate it 9.3/10 overall.
StackLab starts at $119 a month. That number holds across doses, so titrating up does not move the bill. The pricing table above lists every tier.
StackLab says it treats patients in all 50 states.
StackLab lists compounded semaglutide and compounded tirzepatide.
StackLab lists compounded GLP-1s only. A licensed compounding pharmacy prepares them: same active ingredient as the brand drug, lower cash price, and no FDA approval of the finished product. That last part is the one readers underestimate, and the review above says why.
Check whether StackLab bills your insurance before you sign up. Compounded GLP-1s are rarely covered by insurance, so plan on paying the listed cash price.
StackLab says the price covers medication, the clinician visit, shipping, lab work and coaching. The strip near the top of this review shows what is included and what is not.
You fill in an online intake, a licensed clinician decides whether a GLP-1 is appropriate, and if the answer is yes the medication ships to you. StackLab runs that whole sequence on its own site.
We found no FDA warning letters issued to StackLab. Before you buy, weigh these: Its semaglutide and tirzepatide are compounded rather than FDA-approved, so they have not been reviewed by the agency for safety, effectiveness or manufacturing quality. None of them rules StackLab out, but each is worth settling before you pay.
Other sellers we cover include bmiMD, Live Vital, and Oak. Which one fits depends on the medication, the monthly price you can sustain and whether it ships to your state, so compare those three facts before you switch.
