Simple Peptide Reviews

A Reliable & Trusted Supplier of Research Peptides

I have tried about a dozen or so research peptide suppliers over the last couple years and SimplePeptide.com is probably my favorite. The products are high quality, prices are reasonable, shipping is instant, and the customer service is second to none. Selection is somewhat limited, but they have most common research peptides. Trustpilot needs to correct the website address- It is simplepeptide.com not simplepeptides.com

Absolute Garbage

Absolute Garbage. Bought their Reta and got a horrible reaction. Called customer service and they blamed me for not injecting it properly. Are you kidding me

Do not buy from this supplier

Do not buy from this supplier. Horrible experience, and low quality. Bought epitalon peptide and never fully dissolved after reconstituting. Customer service was not helpful and focused on storage explanations instead of addressing the fact that the vial would not properly dissolve.

Fantastic Customer Service

Great customer support!! They got back to me on a Fiday night. Haven't had any issues with the products. Fair prices and great customer service. I don't understand the negative reviews. I tell my friends about the company.

Effective products, ships within a day

This company was my first source of peps; ordered the Tirz, RETA, and MOTS-C and they were all effective and for the prices, you can't complain. What I really did appreciate about this company is their delivery service. Not even a day after ordering, they ship out and I would receive the products soon after. Every other company I ordered from would take 2-3 business days before they ship out, then another 3-4 business days to receive. Can't complain!

Legit vendor with endotoxin testing

I've done a ton of research on peptides and the industry as a whole. From what I can tell, it's a tough space to operate in, so I give a lot of credit to the people doing it right, like Simple Peptides, under challenging conditions. I also looked into the owner on LinkedIn, and they seem like credible business professionals, not random people with no names. A friend of mine had incredible results with Simple Peptides, so I used them as my starting point when I began my own journey in early March — and I've had great results so far as well. Their pricing is very competitive, and their shipping is fast — same-day FedEx label, and at my door a couple of days later (they're in FL, I'm in CA). I've only had one customer service interaction and they were very quick to respond. My overall takeaway is that these are good people who care about what they're doing. I also really appreciate that they test for endotoxins and clearly show the results — that's very meaningful to me. Overall, I'm very happy with them and plan to continue using them as my peptide vendor.

Low quality Retatrutide

Low quality Retatrutide, don’t waste your money.

Good customer service, so-so quality

In terms of business / customer service I give them 5 stars- order processing is fast and transparent. Shipping is fast as well. So far I have placed 5 orders with them totaling 29 vials and $1400+. In terms of quality I am less impressed. Most spesifically I am referring to the CJC/IPA 5mg/5mg blend. It stings worse than GHK-Cu, and it shouldn't sting much at all. The fact that it caused immediate, severe injection site site reactions (ISR) indicative of a heavy Trifluoroacetic Acid (TFA) remnant. While their CoA shows high peptide sequence purity via HPLC, the physical reaction indicates their vendor's synthesis lab failed to properly run the acetate conversion wash prior to lyophilization. If they had counter-ion analysis data to verify the TFA percentage, as standard MS/HPLC does not quantify this, they would have seen this. This is a common issue with CJC-1295 synthesis, so the acetate conversion wash is an important step, which was either skipped by the vendor or performed improperly.

Great experiences, not one complaint

I have had great experiences with this company. Fast, reliable shipping. Quality peptides. Been ordering sometimes monthly for a year. Not one complaint.

SCAM!!

SCAM!!! SCAM!!! SCAM!!! I received empty vials and now I can't login to contact them for a replacement/refund. $130 SCAM! SCAM!!! SCAM!!!

Quickest processing and shipping - QUALITY PRODUCTS

Quickest processing and shipping, "BY FAR"! I never had a bad experience and the customer service responses so quickly everytime. Definitely in my top 3!

Second CJC/IPA batch stung and caused side effects

The first batch of cjc1925/ipa seemed great. The second batch stings and big swelts for days. Also having weird body aches, feeling off, insomnia, flu like pains and terrible recovery. I had to throw it out half way through Its stings more then the GHK-CU! Can't be good quality.

Received empty vials

Was excited to start my healing journey. Easy payment, quick delivery, but empty vials! So disappointed that there are so many scammers out there.

Fast fix on a lost shipment

I've been purchasing from them for close to a year. They offer great products and customer service. I recently had a lost Shipment and it was impressing how fast they jumped on the issue to ensure my delivery made it to me as fast as possible. I would recommend this company gor sure.

Good quality and shipping, one B12 floater

I have done several orders in the past 12 months, and both quality and shipment were good. One of the nasal spray leaked some liquid, and they resend it. My only concern was with a B12 that had some sub-millimeter translucid floater inside. I noticed them only after my G30 needle was obstructed during the draw. I kept the bottle in the refrigerator and it was pierced only 4 times with a G30 needle (I know, intramuscular require a G27), so I cannot think it is a contamination caused by me.

Crypto checkout was smooth

Paid with crypto and the checkout process was quick and easy, no issues confirming the payment. Order tracking updated accurately the whole way.

Volume discount made a bulk order worth it

Ordered 10 units of the same product to hit the bulk discount tier and it worked out to a solid price per unit compared to other vendors I checked.

Melanotan II didn't feel as potent as expected

Melanotan II didn't seem as potent as what I've gotten elsewhere, which was disappointing since I'd read good things overall. Everything else about the order was fine.

Better than most in this space, still verify your COAs

Compared to some of the sketchier sites out there this one feels legit, real customer service, real shipping updates. Still recommend checking the Finnrick results per product since quality isn't identical across the whole catalog.

Ipamorelin has been rock solid every order

Been ordering ipamorelin from them for months now and it's been consistently good. Packaging is clean and professional, no leaks or damage ever.

Tirzepatide vial seemed stronger than labeled

Noticed the tirzepatide seemed to hit harder than the labeled dose would suggest, which lines up with something I later read about batch variability. Would like to see more consistent dosing between batches.

Order never shipped and refund took forever

My order sat unprocessed for over a week with no tracking info. When I asked for a refund it took several follow-up emails before it actually happened.

Fair prices and instant replies from support

Prices are reasonable and every message I've sent has gotten a fast reply, usually within an hour or two. Feels like a real family business rather than a faceless site.

Had to make an account just to see prices

Wanted to compare prices against a couple other sites but you have to register an account before the catalog even shows up. A little annoying but not a dealbreaker once I was in.

BPC-157 had trouble dissolving fully

Had some trouble getting the BPC-157 to dissolve fully compared to other vendors I've used. Reached out about it and didn't feel like the response addressed the actual issue.

Semaglutide worked exactly as expected

The semaglutide I ordered has been consistent every time. Checked the Finnrick results before buying and they matched what I experienced. Would order again.

Ordered before the cutoff and it shipped same day

Placed my order right before the afternoon cutoff and it still shipped same day via FedEx. Arrived two days later in discreet packaging. Support answered a pre-order question within the hour.
