Why should you look at a menu instead of a membership homepage?
Because $365 a year sounds cheap until you only needed a $9 ferritin.
Function, Superpower, and Rythm sell a package. GoodLabs sells a cart. If you already have years of Quest and LabCorp results, you may not need 160 new markers. You may need three. This page is the cart.
How I would actually order: how GoodLabs works. Whether Function is worth $365: is Function Health worth it.

I start people on a comprehensive panel if they have no recent full picture. If they already have the history in Quest or LabCorp, I would buy the gaps. Open GoodLabs with 20JO.
What do single tests cost?
This is the part memberships cannot copy without breaking their math.
| Test | List | With 20JO (first order) |
|---|---|---|
| CBC w/ Differential | $4 | $3.20 |
| Metabolic Panel (CMP) | $5 | $4.00 |
| Hemoglobin A1c | $4 | $3.20 |
| TSH | $5 | $4.00 |
| Vitamin D, 25-Hydroxy | $14 | $11.20 |
| Testosterone, Free and Total | $15 | $12.00 |
| Ferritin | $9 | $7.20 |
| Apolipoprotein B | $12 | $9.60 |
Rechecking one marker should cost one marker. That is why I did not stay on Function at $365 a year or Rythm at $79 a month. See vs Function and vs Rythm.
If that's you, here's the move. 20JO is 20% off the first order. That's it.
Opens goodlabs.com. Code 20JO is 20% off the first paid order.
How does a GoodLabs cart compare to a membership year?
Memberships look cheap on the homepage. Carts look cheap when you only needed three tests.
| Your year | Membership | GoodLabs (Quest, first order with 20JO) |
|---|---|---|
| No baseline, want a huge panel twice | Function $365, mid-year redraw included | Two comprehensive panels is $195 + $195 list. Function can win on tests per dollar. |
| One big panel, done until next year | Superpower $199 in most states ($399 NY/NJ) | Comprehensive ~$156 with 20JO. Close, no year attached. |
| Recheck iron, thyroid, ApoB | Still $365 or $199, or Rythm at ~$79 a month | Ferritin $9, TSH $5, ApoB $12. Or Heart Health $55. |
| One $9 ferritin in July | You already paid the year, or another Rythm month | $9, or $7.20 with 20JO on a first paid order |
Longer verdict: is Function Health worth $365. Superpower: GoodLabs vs Superpower.
What does 20JO actually do?
Twenty percent off the first paid order. That is the whole code.
It is not a stack of coupons. It is not 20% on order two. Apply it at checkout and confirm the discount line before you pay. If 20JO ever fails, I want the email: hello@triedgoodlabs.com.
If you buy through this site I may earn a commission. You do not pay extra. Open GoodLabs with 20JO.
Can I get testing free?
In some cities, if you donate blood at a partner center. Not everywhere.
Where they partner with a blood center, extra vials can come off the same needle and the labs can be $0. Check your ZIP before you plan a week around it. If they are not live near you, you pay the cart. Donation is a door, not the default.
Best for
Anyone who wants to see real cash prices before they join a membership.
Avoid if
People who want one bundled panel twice a year and do not want to think about a cart. Function or Superpower may fit that.
