Question 1

How does peptide group testing work?

ACS Peptide Testing Labs · Accepted Answer

One organizer collects a sample from a shared lot, submits it to ACS under a group code, and pays a single fee. When the COA is ready, we deliver it to the organizer, who can share it with every participant. Costs are split however the group decides.

Question 2

How much does group testing cost per person?

ACS Peptide Testing Labs · Accepted Answer

The lab fee is the same as a single blind purity + identity test (typically $150–$300). Split across 5 buyers that is $30–$60 each; across 10 buyers, $15–$30. Request a quote for exact pricing on your peptide.

Question 3

Can we combine group testing with blind testing?

ACS Peptide Testing Labs · Accepted Answer

Yes. Most groups run both: the analyst is blinded to the vendor, and the cost is split across the group. That is the strongest verification setup for forum and community buys.

Question 4

Who is the organizer and what do they need to do?

ACS Peptide Testing Labs · Accepted Answer

The organizer is whoever submits the sample and receives the COA. They handle the shipping, pay the invoice, and forward the completed COA to participants. ACS communicates only with the organizer.

Question 5

What is the turnaround?

ACS Peptide Testing Labs · Accepted Answer

5–7 business days from when the sample arrives at our Florida lab.

Question 6

Can Reddit or Discord communities use this?

ACS Peptide Testing Labs · Accepted Answer

Yes. Group testing is popular with r/Peptides and Discord research groups organizing verification pools. See our peptide testing FAQ for how the workflow runs.

Question 7

What tests are included?

ACS Peptide Testing Labs · Accepted Answer

Standard package is HPLC purity plus LC-MS identity. Optional add-ons: LAL endotoxin (USP <85>), heavy metals (ICP-MS), residual solvents (GC-MS), and Karl Fischer moisture.

Question 8

How is the sample shipped?

ACS Peptide Testing Labs · Accepted Answer

Overnight courier with cold packs, in a sealed vial from the shared lot. We send the organizer detailed instructions and a submission form when the quote is accepted.

Group size	Lab fee	Per buyer
1	$200	$200
5	$200	$40
10	$200	$20
20	$200	$10
