Customer reviews
Every review here is tied to a real delivered order — we invite customers 21 days after delivery so reviewers have had time to reconstitute and actually use the vial. Nothing is solicited or paid; we do not filter out negative reviews.

Face-cream in my usual store went up again so I went looking for something my friend Wendy at book club had mentioned. She was right. Skin plumper. One knock — the crimp on one vial looked a little crooked but the seal was fine so I used it anyway.

Jean-Paul in Trois-Rivières
63, son recommended after he tried it. Ordered from Sherbrooke, ma commande est arrivée en 4 jours, c'était rapide. Getting back into hockey stands with my grandkid this fall, want the stamina. One vial's label was upside down, funny but harmless.

Buddy on my hockey team told me about this after last season. 32 with a newborn, was expensive elsewhere so I tried this. Package came fast to Barrie, less tired even on the early mornings.

Ordered from Sherbrooke, ma commande est arrivée en 4 jours, c'était rapide. My sister told me. Cravings are less. Merci.

Costco doesn't sell this LOL
Costco doesn't sell this LOL so my curling-club buddy told me where. Retired welder, hands ache every morning. A couple weeks in and mornings are looser. Only ding — no invoice in the box which threw me for a loop, thought maybe I'd been had. Support confirmed the order and that was that.

Never got a reply from support. Order took 14 days. Ended up canceling my card just in case. Package showed up eventually. I'm not saying it's a scam but I'm not doing this again.

Wife found the site through a Facebook group for busy moms. Trying to be healthier before our little one starts kindergarten. Fast to Ajax, everything in the box. Grateful.

Sasha in Kitchener
Vials came, tracking said 2-4 days, arrived on the following Thursday. Not the end of the world but not what was promised. Emailed customer service and got a fine but slow reply three days later. Powder in one vial looked yellowish, they said it's normal for this peptide. Might reorder, might not.

SCAM never arrived. Opened dispute with Visa. Two weeks later they finally shipped it and I got tracking but way too late — I already told the bank to reverse the charge. Whole thing was a nightmare. Would never order again.

Site was really hard to figure out on my phone. Called my son to help. Once he did it, order came fast — 3 days to Kingston. Might have been 5 stars if the checkout wasn't such a pain for a person my age.

Package sat at the Loblaws Canada Post depot for 2 days before I got the pickup notice. Then the first email I sent asking about tracking got no response for a week. Second one got a quick reply. It's here now but I was worried the whole time.

Nikolai in Vaughan
Wife bugged me for a month to try, glad I did. Not as tired in the evenings with the baby. Fast shipping and vials look real.

Nadia in Regina
Fast shipping. Vials look good. A few weeks in, less tired in the evenings. Kids get more of me at night which is what I actually wanted.

kev_burlington
Not for me, this is for my wife — she's been asking for months. I set up the account because she's not great with online stuff. Fast to Burlington. She says the vials look the same as her last batch from a different site.

Gabriel in Winnipeg
Bought for my wife's face and figured I'd try a couple vials for a nagging knee. Delivery was quick. Only reason 4 stars is the website was confusing at checkout, took me three tries.

Gym-mate told me about it. 33, dad of one, trying to be healthier. Package here in 3 days to St Catharines. Getting to the gym more often. Only reason 4 stars is the site was hard to figure out at first.

Got it delivered to my postbox at Shoppers because I work days. Whole thing was easier than I thought. Down a jeans size already.

Been on this a few weeks
Been on this a few weeks — jury's out on whether it's the peptide or just more sleep. Delivery was on the longer edge of the estimate but still fine. Checkout on my phone was a bit clunky, took two tries. Might reorder.

So my brother-in-law's girlfriend put us onto this after her wedding. Package here in 3 days, vials look real, feels legit. Ordering more.
How we verify reviews
- One review per delivered order. The review invite is triggered by the carrier delivery scan, not the order date, and only sends once per SKU per customer.
- 21-day delay. We wait three weeks so reviewers have had time to reconstitute and use the vial rather than review the box.
- No filtering by rating. Three- and four-star reviews are published alongside five-star reviews on the product pages. Removals only happen for spam, off-topic content, or personal-information leaks — never for negative sentiment.
- No solicited or paid reviews. We do not offer discounts or credit for leaving a review, and we do not have any partnership with review-writing services.
Prescott Bio products are sold research-use-only. Reviews reflect the reviewer's own research work; nothing on this page is a medical claim. See the legal disclaimer.
Frequently asked questions
-
How do you verify these reviews?
Every review is tied to an order in our order database. We invite customers to review 21 days after a delivered order, so reviewers have had time to reconstitute and actually use the vial. We do not accept solicited or paid reviews, and we do not filter out negative reviews — you will see 3-star and 4-star reviews alongside 5-star reviews on the product pages themselves. -
Are all reviews shown here?
This page shows the 20 most recent reviews across the whole catalog. Each product page shows every review for that specific SKU, including older ones. To see the full review set for a molecule you are considering, open the product page from any tile above. -
Can I leave a review?
Yes. After your order is delivered we send a one-time review invitation to the email on the order. You can rate 1 to 5 stars and leave a short comment. You can update your review at any time by replying to that email. -
What if my experience was not what the reviews suggest?
Reach out. Every vial is HPLC + mass-spec tested and covered by our 48-hour replacement guarantee — see the guarantee page. If the vial itself is fine but the outcome does not match, email support and we will send the batch-specific COA and discuss what may have happened. Research work is variable; we take feedback seriously.
