Great pricing, fast shipping (no fancy boxes....so you arent paying extra for unnecessary cost). The website is very easy to navigate with a new kit builder to speed up the process and links to all…

As someone who ventured deep into grey and dabbled in reselling, I gravitated toward this board because, IMO, it’s the best source for what’s happening in retail.
I’ve been moving away from grey and have come to appreciate what retail sellers are doing. Testing has increased exponentially, prices have dropped dramatically, and it’s becoming a competition over who can test the most while charging the least.
As a busy professional who has no interest in group buys or organizing group testing anymore, I see tremendous value in this. At this point, retail kit pricing is rivaling grey + independent testing, both dollar for dollar and in time saved.
That said, is Crush doing this better than anyone right now? Nexaph has been my top dog, but Crush seems to be taking the lead. Pricing is becoming significantly more competitive, and testing appears even more extensive.
Curious what everyone thinks.

Peptide: MOTS-c

I recently bought pinealon and dsip from American peptides. I used dsip first then pinealon the next day. After that second day I woke up with my tongue black and spitting out a bit of black mucus. I dropped the pinealon for now just cause it didn’t happen the first night with dsip but now on the last day of my cycle with dsip I get the black tongue again. I’m going to go get checked out but I was wondering if anyone had anything like this happen before?
How do you keep things like BPC-157 and Wolverine cold while you travel? Should I make a pen cart with the amount I need for my trip? Planning to fly somewhere for the holidays and trying to figure out what works best. I just saw the ice pack and travel case, but I was hoping to avoid leaving it in someone's refrigerator while traveling. Do I really need to keep it cold for 4-5 days?
So I decided to send two samples to Krause for testing and comparison.
Krause is very behind on the tech but still usable The process is long and requires filling out a customer request and then another form on the peptides. These are PDF forms. You mail them in with the samples and email them the tracking. About a week later I received an email with a link to quickbooks which contained my estimate which you approve or deny. I approved it and about 5 days later received a link to quickbooks to pay the amount due. I paid it and received the result with in hours.
First off its klunky but they are cheap I paid $190 for two samples. I would do all of that again for that price. I also love the fact that they provide all of the data.
The results. I am sorry but I am not buying 99.9pct purity. I am not saying its not possible but its unlikely. I am attaching the Chromate and Krause results. I will have results from BT labs as well. I don't have that yet though.

I placed an order for Retatrutide (Reta) with Flawless Compound and unfortunately it has been a very disappointing experience.
The first order all turned cloudy right after reconstitution. I reached out to their customer service and they quickly sent a replacement. However, the replacement ended up being significantly worse than the original. After reconstituting with high-quality BAC water, the solution was very cloudy, refused to fully dissolve, and had a noticeable white gel-like substance floating inside (looked like some kind of contaminant).
I’ve reconstituted many Reta vials from different vendors before and it’s usually one of the easiest peptides to mix. This is clearly not a reconstitution issue on my end — it’s a product quality problem.
What’s especially frustrating is that Flawless provided online verified COAs and testing documentation like other reputable vendors, but it feels like they’re not consistently following through with the quality they advertise. This is the only Reta vendor I’ve had these issues with — every other source I’ve used has been fine.
At this point I’ve requested a refund and I won’t be using these compounds for any research. I hope they sort out whatever is going on with their batches, because the customer service response time was good, but the product quality needs serious improvement.

Would not recommend until they fix the these issues.

I was going to buy a couple of kits this morning and found that ' pkg. insurance' alone on just one kit is $20! I have never paid even $5 for pkg insurance from any vendor. Didn't even want to move on to shipping charge.
Sorry Studz, I'm sticking with Nexaph and the few others who are more reasonable in their misc. add-ons.
Ok, this is my journey. I hope this helps people not make the same mistakes.
Pre Peptide Critic: Newbie who didn't know sh*t
Pure Labe Peptides - Fake COA's. Fake carbon copy of Hospira. Bad reaction over a week of pain
Peptide Solutions - Felt nothing from the products Reta included. Fake COA's
Found Peptide Critic - Everything Changed
Mile High - Great Products, but has Kovera labs on some
Glacier - Also Great but all Kovera
Southern Amino - Great, my go-to for what EZ doesn't carry
EZ and Nexaph - My absolute go-to. Pricing and product consistency are top-notch
Crush - High hopes, but their inventory control is a joke, and the constant marketing ploys have turned me off. Products are good, though.
Grey
LN and LI Peptide - Great until they ripped everyone off
GroupBuyKits - waiting for the first order, but Randy says no go and that's enough for me. Update group buy list is a scam
Lets all share!!!! and help more people
My cat/rat is struggling with energy and I'm interested in NAD+ but I'm finding dosing protocols all over the place. Can someone point me in the direction to help my research?
Is Mots-c or something else better?
My guinea pig has been on 2mg Reta dosing every three days combined with 0.5mg Eloralintide once weekly with great results. Down 30lbs so far. Well I bought a kit of cagrilintide from Nexaph as they didn't have eloralintide at the time. My guinea pig has now worked through the eloralintide supply and it's coming time to recon the cagrilintide.
Has anyone made this switch, and if so what dosing did you start at? I know it can start at the bottom and titrate up, but thinking that may not be necessary.
What are your thoughts?
I jumped straight to Reta and have lost 30+ pounds in six months.
My significant other has been, and is currently, on Tirz (12.5) prescribed by her doctor. After seeing my success, she wants to transition to either the Tirz/Maz combo or the Reta. Are there any suggested processes?
If Tirz/Maz is the route, should you (a) keep Tirz at 12.5 and slowly add Maz, (b) reduce Tirz by some amount and also slowly add Maz or (c) some other process?
If Reta is the route, should you (a) stop Tirz and replace with Reta (titrating up), (b) reduce Tirz by some amount and also slowly add Reta or (c) some other process?
I would presume 2-4 weeks for each "step".
Experiences and suggestions?

I wanted to take a moment to share my vendor experiences and rankings with the community.
I'm relatively new to peptides, having started my research journey with Reta. After approximately a month of researching the peptide itself, along with some firsthand experience from a family member, I decided to place my first order with Elite Biogenix.
That was before I discovered this incredible forum, Peptide Critics. Since joining, I've learned a tremendous amount, saved money, gained valuable insight into vendors and testing, and had the opportunity to connect with some genuinely helpful and knowledgeable people. This community has been an invaluable resource.
Below are my personal vendor rankings based on my purchasing experiences, product quality, packaging, testing transparency, shipping, pricing, and overall satisfaction. These rankings reflect my own experiences and are subject to change as I continue testing and purchasing.
A Tier – Highly Recommended
Consistently good experiences with product quality, packaging, testing transparency, and shipping. COAs are provided, products have performed as expected based on my experience, shipping is fast, and pricing is reasonable with frequent sales.
Penguin Peptides
B Tier – Solid Experiences
Good overall experiences with product quality, packaging, shipping, and COAs. Products have performed as expected based on my experience. I simply haven't ordered from these vendors as frequently as my A-tier vendors. Pricing has been reasonable.
Crush Research (prior to ownership change)
S1Research
NuraPeptide
C Tier – Undetermined
Pricing is attractive, and they seem to consistently offer competitive deals and sales. However, following the ownership change, I'm still uncertain about consistency and product quality. I have another kit on the way and will update my ranking once I've had additional experience.
Crush Research 2.0
D Tier – Overpriced
My experience with the products was generally positive, and they performed as expected. However, pricing was significantly higher than comparable vendors, making it difficult to justify the additional cost.
Soma Chems
Elite Biogenix
F Tier – Quality Concerns
I've experienced issues with vial quality, particularly when removing the flip-off caps from new vials. This raised concerns regarding overall packaging quality and consistency.
Southern Aminos
F- Tier – Extremely Disappointing
Unfortunately, this has been my worst vendor experience to date. Based on my experience, the product quality was extremely disappointing and fell well below my expectations. After giving this vendor a fair opportunity, I was left thoroughly dissatisfied and would not consider purchasing from them again.
I personally would not recommend this vendor based on my experience.
Flawless Compounds
Final Thoughts
These rankings are based strictly on my personal purchasing experiences and observations. Everyone's experience may differ, and I'm always open to updating my rankings as I continue learning and trying different vendors.
Thanks again to everyone in this community who shares information, testing results, and honest feedback. It's made navigating this space considerably easier, and I appreciate all the contributions from fellow members.
