FAQ
What is this community?
A literature library for people who handle research peptides. Every compound ZC Labs carries is written up from primary sources — mechanism, evidence, safety, regulatory status — including where the evidence doesn't exist.
Is it free?
Yes, all of it. The open courses and the Vault's per-compound literature reviews are free to every member.
Do I need to be a customer?
No. Every course is open to every member. There is nothing to unlock, and please do not post an order number in the community — order questions go to [email protected].
Can you tell me how much to use?
No. Not in a post, not in a DM, not "off the record."
Every compound lesson reports what the published studies administered — in what species, by what route, for how long — and then explains why those figures don't transfer. That's the honest answer, and it's the only one available.
Why is the community strict about that?
See the Rules post. Short version: the FDA warning-lettered seven peptide sellers in March 2026 and quoted one company's own community forum as evidence.
What does "research use only" mean?
The products are sold for laboratory research. They are not drugs, supplements, cosmetics or food, are not FDA-approved, and are not for human or veterinary use. The Regulatory Record course covers what that status does and does not mean.
Do you publish certificates of analysis?
Yes — every lot, at zclabs.shop/coas. The COA & Supplier Literacy course teaches how to read them, including how to spot a fake.
I have an order problem.
Order, shipping and payment questions go to [email protected], not the community. Admins here can't see your order.
Can I promote my brand or affiliate link?
No. Post about the science, not your storefront.
