    We’ve added a new way to strengthen reviews on Peptide Critic: Verified Customer badges.

    If you have purchased from a vendor and left a review, whether it’s a new review or one you posted previously, you can now submit private proof of purchase for moderator verification. Once approved, your review will receive a ✓ Verified Customer badge so other community members know it comes from a confirmed buyer.

    How to add proof
    Go to My Reviews, log in using the email address associated with your review, and upload a receipt or order screenshot for the review you want verified.

    For privacy, your proof is never displayed publicly. It is visible only to you and Peptide Critic moderators.

    You may black out any personal or sensitive information. We only need to see:

    Vendor name, website, or logo

    The product reviewed

    Purchase date

    Order status, such as paid, completed, shipped, or delivered

    The last 4–6 characters of the order number

    Adding proof is optional, but it helps make the community’s reviews more transparent, credible, and useful for everyone.

    I just started down this rabbit hole a few weeks ago. It started because my insurance would not approve my Zepbound. I tried thru Lilly direct and it was still too expensive. (I don’t qualify from a weight perspective, but I have a lot of autoimmune issues.) I’m so glad I found this group. There seem to be very level headed people here.
    A bit about me… I’m an MD, and I never thought I’d go for the peptide market. I drank the ‘straight and narrow Western medicine’ kool-aid pretty hard my whole life. But learning what I have learned these past few weeks has been quite enlightening. Before med school, I have a background in bench science (biochemistry and genetics), so it helps that I have done research on rats in that past life. My new rat I’m researching on currently is named Maynard.
    I ordered tirz and Reta through vendors from this site and message board. Now I’m interested in taking it a step further for Maynard’s longevity and quality of life. This will be interesting. 🙂


    Is Maynard a pretty rat?

    I have used Finnrick for testing before, but I have probably sent in too many samples and they have not given me the send to info for my latest ask.

    My vendor sent me 2 differently labeled boxes of Tirz and I asked Finnrick to test one of each.

    The vendor said ‘the guys’ probably ran out of labels and that they are the same batch.

    I want to test both… but I don’t want to break the bank.

    Suggestions ?

    ( my buys are all for my personal use, I don’t sell )

    Thx !

    My rat is complaining of skin sensitivity / tingling since starting reta about a month ago. It’s not terrible, but quite noticeable. Mostly legs, and mostly with fabric movement like a blanket. I have seen in these threads and other places online that this is a known side effect of reta. He is on 2 mg, split at 1 mg on Mondays and Thursdays. He does tirz 2.5 twice a week as well. No other peps.
    Does the skin thing go away with time? If he escalates his dose, is it likely to get worse? He has absolutely no other side effects from either med. He was wondering if he was even jabbed with anything at all, if it wasn’t for the skin thing (and the modest weight loss).


    @jennn primarily because it was easier to find, and cost less. So, if it worked I would move to Survo when that runs out.

    Quality products and I love the pricing for the 5-vial pack. I just added the KLOW to my RETA protocol, and am pleased with the quality.

    I was turned to Apex Amino from a friend. I was very weary of where to purchase from because of fake COA's. When I looked at the website I saw that all the products had a COA. They were also able to be verified via the QR code on the COA. I still had questions and reached out to customer service. Any question that I had about a COA or about a product they were fast to respond to with an answer. They were fully transparent and never felt they were hiding anything. I have ordered a ton of products from them and nothing but quality. I would recommend this vendor to anyone. They are based out of Florida, and so am I. All my products except for one order has been next day delivery. The other one came two days later. Definitely a vendor I trust.

    Does anyone in here have any experience with Kisspeptin-10? If so have you done blood work before/after running a cycle? I'm curious on the changes to hormones from before-after.

    For all of the Crush fans...I got an email earlier today about another presale event happening at Crush starting Friday Aug 7 at 5pm Mountain through Sunday at 11:59pm...or until they sell out. 30mg Reta for $1/mg.

    @BeeKind the tesamorelin I got was from ILS but the Reta from vanguard
  • R

    Janoshik said one thing. I jad it tested. My coa was completely different. What's your experience?


    @Superpep Not sure whats wrong. They actually are owned by the company supplying the raws so they source from themselves and then they complete the manufacturing process by freeze drying and batch control, which occurs here on US soil. So once again, not sure what was wrong. The actual point was they have control over batches, so the COA's are meaningful as they relate to an actual batch with cap colors and crimps which THEY CONTROL without relying on a factory in China. Hope that cleared that up for ya
  • pep_researcherP

    @pep_researcher For sure, they have amazing R&D, but its the evil empire. They have done the impact analysis on peptides and determined what to bring to market that doesn't impact other medications, profit centers. They are slow rolling Reta; it's obvious. While they do the slow roll they are creating market buzz, and trying to drive up black market prices. Its all strategy.

    Anyone else researching this one? Been doing a week of 25mg sub-q with good results, now moving to 50mg (full vial) per pin. The looks of it in the barrel are such that it will light the injection site on fire but it is a total nothingburger.

    Seems the best to time the pin is 20 minutes or so subsequent to an NAD+ pin, which I am doing. 100mg-150mg NAD+ pin, then the 5-Amino 20 min later. Daily, no breaks. A nice double-rush of clean energy.

    FWIW- I am 95% optimized with good muscle mass and low fat, 65 yrs old.


    I start my premix HVY today. I took 5 units which works out to about 6.85mgs. I am going to double it tomorrow. I need to find the sweet spot.

  • rickdiculousR

    Hi everyone! Happy to be here, I've heard about peptides here and there online and stumbled upon a few of Peptide Critic's tutorial videos and decided to look into the website. I'm very new to peptides and whatnot but am a huge science nerd so the bits of research papers I've read so far have been interesting! I have mainly looked into Retatrutide but am curious about peptides as a whole, the research is super interesting. If anyone has any general advice or things you typically share with newcomers I am all ears, lovely to meet you all and happy to have found a space to discuss! :DD


    Welcome to the community!
  • J

    So I ordered from northline. 10 mg tesa. 2 vials around $150. So that’s 10 days? What is best economical and high quality way to get 3 months of tesamorelin?


    @jimmygunns You'll need to buy kits of Tesa to get a good full cycle in. Check out Nexaph or take that full gray dive.
  • I

    Been hearing hospira bac is the highly recommended one... Anyone have a recommendation on where to buy at a good price? I've seen them around 16-20$ per 10ml bottle

    I’ve had a great experience with PX Peptides. They have a great selection and availability of peptides, making it easy to find what I’m looking for without constantly running into products being out of stock.

    The quality has been excellent, and I really appreciate that their products are verified through third-party lab testing, which adds an extra level of confidence and transparency. Their ordering process is straightforward, and the shipping is consistently fast, with orders arriving well packaged.

    Overall, PX Peptides has been a great company to work with. Great peptide availability, high-quality products backed by third-party testing, fast shipping, and excellent overall service. I would definitely recommend PX Peptides to anyone looking for a reliable peptide supplier.

  • atlas01A

    Just curious if anyone has bought their recent batch. The last two have tested at 97-98% and I’m curious if it’s safe. MOTS-C isn’t really practical to buy single vials, and for the price I am tempted to get it.

    @atlas01 anything above 96% is technically pharma grade, but I would stick above 98%
  • E

    Peps are probably going to get even cheaper with Labor Day sales. You might want to consider holding off buys until then. Tell vendors what you want and see if it happens.

    I want: NAD+ BUFFERED, SS-31 and Survo.


    @atlas01 This is my hope as well.
