How group testing works
- 1
Discover & sign up
Find the site, browse public groups, register with an email and a chosen alias. Real names are never collected.
- 2
Find a group
Browse public groups, enter a Group ID, click an invite link, or accept an email invite. No fit? Use the Create wizard — it walks you through the three setup axes and either locks the rest or defers it to a vote.
- 3
Join
In the Open phase, pay a $5 deposit that is credited toward your final share. In the Payment stage, pay your full share on the platform — the share is computed live from member count, sample donor credits, and shipping cost. If the group is in the Funded phase and beyond, you can still join late to see the test results.
- 4
Donate a vial (Optional)
If you're a sample donor, the Group Manager marks you as a donor and assigns a dollar value to all donor vials, which becomes a credit against your share. You ship to the lab or to the group's Lab Shipper and enter a tracking number so everyone can track your sample's shipping.
- 5
Finalization
The platform computes the final per-share price, the funding goal, and which vial holds which tests. The group moves from the Open stage to the Payment stage.
- 6
Pay the share
Group members pay their final share. When every share is paid, the group hits the Funded stage.
- 7
Shipping
GTH Admins signal when it's safe to ship samples your selected lab(s). Vial Donors send samples to the Lab Shipper (or straight to the lab, if the Vial Donor is also the Lab Shipper). The Lab Shipper consolidates all samples and ships them to the lab. Tracking information is added by shippers and is visible to everyone.
- 8
At the lab
GTH Admin coordinate with the lab. The group sits in the Laboratory stage. Typical turnaround is 2 to 14 days from when the lab receives the samples (Depending on the lab).
- 9
Results
Admins upload the COA (file and url link) and the group stage moves to Complete. Every member can read results in their dashboard, permanently. Members may upload additional third-party results for the same batch, subject to Manager approval.
- 10
After the fact (Late Joiners)
Anyone joining after Funded stage pays the full share to join the group and see results. 100% of that amount is distributed as store credit to original members, split fairly based on their total contribution.
What changes for an Independent group
- Joining becomes "request to join → Manager approves." Payment happens off-platform — the Manager posts Zelle / Venmo / crypto instructions and marks members paid manually, one by one.
- Finalization and lab work are run entirely by the Group Manager, not by Group Test Hub staff. For Independent Groups, you trust Group Managers with your payment calculations, lab funding, lab communication, and test results.
- Results are uploaded by the Manager on the group page.
- The only on-platform payments are the $5 group creation fee and Late Joiner payments, both of which are non-refundable.
- Late-join store-credit redistribution still applies — it is universal across every group type.
- A disclaimer banner sits on every Independent group page making clear that GTH is not involved and that the Manager owes the duty of care. Independent group tests should only be joined if you 100% trust the Group Manager(s).
The traditional group test process
Before platforms like Group Test Hub existed, community group testing worked roughly like this. The manual process worked for many people — we built the platform to remove its single points of failure.
Step 1
Someone floats the idea
A member posts in a subreddit, Telegram, Discord, or forum: "anyone want to chip in to test X?"
Step 2
Interested people raise their hands
Participants tell the organizer what they want tested and make sure they have the same batch to test.
Step 3
An organizer volunteers their time and effort
One person self-appoints to start a group, hold the money, get a price quote from the lab, and handle sample logistics.
Step 4
The cost split is calculated by hand
The organizer estimates a per-person share from the lab's quote, the participant count, donor reimbursements, and shipping. Splitting is informal, error-prone, and sometimes requires multiple transactions per person.
Step 5
Money is collected manually
Venmo, PayPal, CashApp, Zelle, Wise, or crypto — paid directly to the organizer's personal account, with no buyer protection.
Step 6
A lab is chosen by the organizer
The organizer may create polls to find out what the group wants tested, or they may just pick their own lab specs.
Step 7
Samples are sourced and consolidated
Either each donor ships their own vial, or one person collects the batch.
Step 8
One person packs and ships
They mail to the lab and pay the lab invoice out of pocket, then re-chase everyone for their share.
Step 9
Everyone waits
With little visibility. The organizer may or may not answer "any updates?" for days or even weeks.
Step 10
Results are redistributed by hand
The lab emails the COA to one address and the organizer posts the PDF to the Discord or subreddit — or, in the worst case, disappears.
Step 11
The group is full
People can't join the group after it's been funded because the payments have been calculated and made already.
Step 12
The COA gets sold "under the table"
Group members may sell the COA to other people who were late to the party and weren't able to join the group test, directly benefiting themselves but nobody else in the group.
Where it breaks — and what the platform changes
| Failure in the manual process | How Group Test Hub addresses it |
|---|---|
| Organizer disappears with the money. | Funds collected by the GTH platform. Members never hand cash to a stranger. |
| Hard to calculate a fair share — donors, shippers, shipping, refunds — all done by hand or an excel sheet. | Automatic, fair per-person pricing recomputed live from member count, donor credits, and shipping line items. |
| Privacy loss from exposing payment handles and identity to a stranger. | Alias-only accounts. Payments via Stripe. We never see card numbers, names, or addresses. |
| Organizer ghosts on updates. | Built-in status tracker (open → payment → funded → laboratory → complete) with on-platform and email notifications. |
| Once the group is funded, latecomers are locked out — no way to join after payments are made. | Late-join stays open after funding. Latecomers pay the full share on the platform and original members are paid back automatically via store credit, reaping the rewards of getting involved in testing quickly. |
| Members sell the COA "under the table" to outsiders — only the seller benefits. | Outsiders can late-join through the platform, and 100% of their payment amount is distributed as store credit to the original members. |
Side by side
| Traditional | Group Test Hub |
|---|---|
| Find people on a forum or Discord. | Browse or create a group on the site. |
| Collect money manually (Venmo / crypto). | Pay through the platform with Stripe. |
| One person holds all the money. | Payments made directly on the platform. |
| Slow lab communication. | Lab communication handled by GTH staff for faster results. |
| Manual cost-splitting. | Automatic per-person pricing (group size, donor credits, shipping). |
| No tracking, the organizer may ghost. | Group test status tracker + on-platform and email notifications. |
| COA emailed to one person, maybe shared. | COA hosted in every member's dashboard and the group page itself. |
| Group closes at funding, latecomers shut out. | Late-join stays open, full share paid on-platform. |
| COA leaked or sold under the table so only the seller profits. | COA stays gated to the group, late-join fees are distributed as store credit to original members. |
Start a group test in 2 minutes
Register for Group Test Hub (it's free)
Register with an email or via Google. You need an email and an alias. That's it.
Join or create a group
Join an existing group from the Browse page, or create your own from the Create wizard.
Choose your three settings (only if creating)
Public or Private. Managed or Independent. Pick your peptide or compound. The wizard explains each required field.
Pay your share (or $5 to hold your spot)
Stripe checkout. Your share is calculated for you — it's the real number, not a guess.
Donate a vial for credit (optional)
Donating a vial or multiple vials lowers your share by the value of the vial(s).
Ship when you get the green light
Wait for the "safe to ship" notice, the group ships samples, and waits for lab results.
Watch the tracker
Open → Payment → Funded → Laboratory → Complete, with email and on-platform notifications at each step.
Read your COA
Results land in your dashboard, and live there permanently. Open them whenever you want. Invite late joiners if they would like to see the group test results.
