Testing and COAs
Hello Stacks publishes a COA page, and the site mentions lot or batch numbers alongside its certificates. It names Vanguard as a testing lab and mentions endotoxin or sterility testing. We did not verify the certificates ourselves.
What's missing is independent data. We found no tests for Hello Stacks on Finnrick, so the only test results available are ones the vendor publishes. Match the lot number on your order to the certificate.
Shipping and returns
Its shipping page lists free shipping on orders over $150 (grand total), with USPS Priority, FedEx 2 Day, FedEx Overnight and a signature-required overnight option. Its refund policy says all sales are final, except when an order arrives with missing, incorrect or damaged items.
What we like
- A named company, PranaCore Life Inc., and a published city.
- COA page with lot numbers, a named lab and endotoxin or sterility testing mentioned.
- 16 of 25 compounds below the median, including NAD+, MOTS-c and TB-500.
- Several shipping speeds and free shipping over $150.
What to watch
- No Finnrick tests found.
- Payment by ACH or eCheck only, per its site.
- All sales final except missing, incorrect or damaged items.
- GLP-class products sold under codes (GLP-1 R, GLP-1 T, GLP-1 S), and small sizes can cost far more per mg.
- Sermorelin and the BPC-157 + TB-500 blend priced well above the median.
How it compares
Hello Stacks discloses its company, city, lab and lot-matched COAs. Vendors with Finnrick data add an independent check it lacks. See all vendors we track, peptide deals this week and our ranked list.
Bottom line
Hello Stacks combines solid disclosure with below-median prices on most of what it sells. The main gaps are independent testing and limited payment options. Buy larger sizes for the best per-mg price and check the COA for your lot.
