HelloStacks Review: Our Verdict
HelloStacks is one of the more transparent stores we list. What we found when we checked on October 1, 2026:
- Certificates by lot: its COA library lists 31 certificates, each with the lot number printed on the vial, the HPLC purity, the report number and a link to check the report on the lab’s own portal.
- Endotoxin testing included: the two certificates we opened, for BPC-157 10mg and MOTS-C 10mg, cover chromatographic purity, assay and an LAL endotoxin test. Many stores we list publish purity only.
- Results we read: BPC-157 10mg tested above 99.80% purity with an 11.68 mg assay, and MOTS-C 10mg tested at 99.07% with an 11.01 mg assay. Both passed the endotoxin test.
- Not every product is covered: the library has 31 certificates against 52 vial products, and some published results sit below 99%, such as humanin at 97.2% and tesamorelin 20mg at 98.51%. Check the certificate for the exact product you order.
- Prices: BPC-157 10mg costs $49.00, TB-500 10mg $59.00, MOTS-C 10mg $59.00, GHK-Cu 100mg $69.00 and NAD+ 1000mg $89.00 before our code.
- Fast dispatch: orders placed and paid before 2pm PST typically ship the same business day, in plain packaging.
- Drawbacks: it ships to US addresses only, all sales are final, and orders can’t be cancelled once shipped.

Estimated Savings with PEPTIDESPC
The code takes 20% off a single unit at the store’s listed price. This table uses the single-unit prices we saw on October 1, 2026, before shipping.
| Product | List price | After PEPTIDESPC |
|---|---|---|
| BPC-157 10mg | $49.00 | $39.20 |
| TB-500 10mg | $59.00 | $47.20 |
| MOTS-C 10mg | $59.00 | $47.20 |
| GHK-Cu 100mg | $69.00 | $55.20 |
| NAD+ 1000mg | $89.00 | $71.20 |
We have not yet tested whether the code combines with the store’s quantity breaks, so count on one or the other until you see both in your total.
HelloStacks Lab Reports and Purity
Every product page shows the certificate for the lot on sale, and the store’s COA library lists all 31 published certificates in one place. Here is what the two certificates we opened showed:
| Product | Lot | Purity (HPLC-UV/VIS) | Assay | Endotoxin (LAL) | Reported |
|---|---|---|---|---|---|
| BPC-157 10mg | VR10808250001-10 | >99.80% | 11.68 mg | Pass, <5.00 EU/mg | April 16, 2026 |
| MOTS-C 10mg | VR0304260110 | 99.07% | 11.01 mg | Pass, <5.00 EU/mg | April 16, 2026 |
Both were issued by Vanguard Laboratory in Olympia, Washington, under A2LA certificate 6377.01.01, and signed by its laboratory director and operations manager. The lab notes that it did not select the samples itself, which is standard for vendor-submitted testing. Our guide on how to read a peptide COA explains what each of these results means.
