CrushResearch — easily my best vendor experience so far

Few orders in, no complaints worth the name.

Ordering and shipping: fast turnaround, 2-3 days door to door. Packaging is solid — COAs are linked right on the bottle labeling by QR code, so you can verify what you're holding without digging through a site or emailing to ask. More vendors should do this.

Pricing: reseller pricing is good, discount code stacking.

Customer service is where they actually separate themselves. Rory clearly gives a damn about the products and the people buying them. No sales BS, no boilerplate, and when something went sideways, (website glitch over sold inventory) he was straight about it rather than deflecting. Provided 3 options to make it right. That's rarer than it should be in this market. You can follow him @rorynotsorry on X.

Only real complaint: they sell out fast. Get on the restock notification list and have your payment method ready to go the moment a drop opens — popular items are gone quickly. Annoying, but it's a good problem for a vendor to have and I'd rather that than sitting inventory.

Recommended without reservation.

Southern Aminos — decent pricing, fast shipping, no support when something goes wrong

They advertise trusted quality. The testing paperwork is there. The service isn't, and that's what this review is about.

Shipping: 2-3 days, tracking worked, no complaints. Genuinely fast. Packaged in the same generic containers you see from grey market sources — Didn't bother me, but worth knowing before you order. You might find a good deal stacking discounts

Product: COA was provided for the lot, credit where it's due. The vial did not fully reconstitute. A chunk stayed fused to the interior glass wall, and once I got it loose it fragmented rather than dissolving. Flakes were still floating after full day of sitting.

Service, which is the actual issue: I opened a claim with the photo. The reply was fast and polite and completely boilerplate. Denied — "we are unable to offer replacements or refunds for reconstitution-related concerns, since many of the factors involved occur outside of our control after delivery" — citing the COA as proof the vial was fine. A COA verifies identity and purity. It doesn't certify that the cake will go back into solution, so it doesn't actually address what I reported. The case was marked Resolved / Denied on the first response, with no appeal path offered.

Bottom line: if every vial arrives good, you'll have a fine experience — the prices and the shipping are legitimately reseller competitive. But their policy puts the entire risk of a bad vial on you, and they will not move off it. $35 was a cheap way to find that out. A $500 order wouldn't have been.

Not ordering from them again. Plenty of vendors in this market to choose from.

Flawless customer service

Good selection and prices with several discounts available. COA's readily available and easy to confirm. Post purchase customer service was the best I've encountered in 2 years of doing business with several other companies. I ordered on a Saturday and received them by Monday. I was kept updated by Flawless and FedEx daily. I don't think I ever received my peptides in 2 days no matter what day I purchased them. Most of the time the average I wait for my deliveries from other companies is 5-7 days. They're on it. Flawless service.

Consistently Does Not Constitute

I have ordered several vials of BPC-157 from Planet Peptide. Normally, they would replace any vials that would not constitute. Now, out of the blue, they have ghosted my emails about 3 replacements of BPC-157 that would not constitute. They finally sent 3 replacements, but Fedex delivered to wrong address and now Planet Peptide is ghosting me again. They will not answer my emails about making Fedex replace the vials. I am constrantly receiving peptides that will not constitute. I will not be doing business with them any longer. Please be careful ordering from them.

Fast Delivery, inactive product

It must have been all filler, unfortunately. Comparing it to two other products and I tripled my normal dose with limited to no results. Switched to a new vendor and that one has immediate impact. Really appreciated the ease of ordering and how fast it can't but it's just not good product.
