Peptime
The most open seller we have checked. It names its testing lab, puts the certificate on the product page, and shows prices to anyone who walks in.
The transparency check
| ✓ | Labels every product research use only | On every card in the catalogue and on the product page. |
|---|---|---|
| ✓ | States purity of 99% or better | Stated site-wide and on each product. |
| ✓ | Names the testing lab in public | Names Finnrick as the independent lab. Almost nobody in this market names one. |
| ✓ | Puts a certificate on the product page | A View COA link sits on the product page itself, before you buy. |
| ✓ | Publishes prices without a sign-up | Prices, sizes and bulk discounts are all visible to anyone. |
| ✓ | Says where it compounds | States it compounds in the United States, and has traded since 2012. |
| ✓ | Publishes a refund policy | Refund, privacy and terms pages are all public. |
| ? | Certificate matched to a jar we ordered | We have not bought from any seller. That is a limit of our method, not a mark against them. |
This scores what the seller publishes and we could check — not how well anything works. No site can honestly tell you that.

Every claim scored above is on their public pages. Prices, sizes and bulk discounts are visible without an account, and the certificate of analysis is linked on each product page before you buy.
Most sellers in this market say a lab tested the batch. Peptime says which lab, and puts the certificate on the page you buy from. That is the single biggest gap between talking about testing and showing it.
What stands out
- They name the lab.
Finnrick, stated in public. A certificate is only worth what the lab behind it is worth, so a seller that will not name one is asking you to take the number on faith. Peptime names one.
- The certificate is on the product page.
Not on request. Not in an email after you buy. There is a View COA link sitting next to the price, before you have spent anything.
- Nothing is hidden behind a sign-up.
Prices, sizes and bulk pricing are all visible without an account or a verification step. You can compare before you commit.
- They say where the work happens.
Compounded in the United States, and trading since 2012. Both are checkable claims rather than vague ones.
What this check does and does not cover
- What they state on their own site and product pages
- Whether a testing lab is named anywhere public
- Whether a certificate is reachable before you buy
- Whether prices and policies are public
- Whether anything in a jar does anything
- Whether the powder matches the certificate
- Whether the compound is safe
- Anything needing us to buy and test a product
