Third Party Testing
I ordered from the chemical plant and plan on third party testing my product. I haven’t received half of the COAs which is fine because no disrespect but I don’t trust COAs from any manufacturer. I’m honestly surprised that nobody is talking about grouping together and pitching in for testing. I will be sending in Tesa, GHKCU, IPA, and BPC157/TB500. If anyone bought the same and are interested in my results DM me and I will provide them for a small fee so I can at least recoup a little money from my testing fees.

I 100% agree with you. Why I joined this group actually and still people just aren’t interested. I eventually bought elsewhere and then just plan to spend the extra on it myself with endotoxins. Honestly I’m shocked at how trusting (?) people are with just taking the manufacturers word for it. Especially with often failed compounds like Tesa. Would love to be on a chat if this group ever moves forward with it.
Reta this Reta that...
Hey all, So I have been on Tirzepitide for about 5 months. Lost the weight I wanted to and am now on a maintenance dose. Good and bad- I am one of those people who really am sensitive to it however and lost 30lbs without going over 2.5mg/week but even on a maintenance dose the and GI issues still are a big issue. Always have been. Tired taking probiotics, lots of water, eating cleaner during the 3rd day, splitting dosages etc. no help. My question is this: Have people who switched to LOW dose Reta notice GI issues and is low does Reta basically the same as Tirz when you have such a small amount of glucagon anyway. Also if I start taking Reta do I have to do a before and after on Reddit with my shirt off because I really don't want to do that either...

@Selina Aguayo thanks for such a thorough reply, Selina! Yea, for me it’s been fits noise - snacking urges so this really helps. I just started training peppermint pills and oddly that helped a lot. Your reply really helped me, thank you!
📢 GROUP BUY & INDIVIDUAL BUY — IMPORTANT UPDATE 📢
We have several important updates for next week. Please read this entire post so everyone clearly understands the ordering, payment, and direct-shipping process. 👇 🔐⭐ PREMIER MEMBERS ONLY Access to the Chemical Plant website will be STRICTLY for Premier Members. ⭐ Premier Members will have access to available Group Buys and Individual Buys. 🚫 The Chemical Plant website is not open to the general public. 🔒 Please do not share access outside of the Premier Member community. Having access does NOT mean you are required to order. Participation is always optional. ❤️ 🇨🇳📅 IMPORTANT CHINESE HOLIDAY & DEADLINE The upcoming Chinese holiday is: 📅 September 25 – October 7 Because of the holiday, we need ALL ORDERS AND PAYMENTS COMPLETED BY SEPTEMBER 17. 🚨 This gives us enough time to: 📋 Organize and sort all orders 💳 Confirm payments and allow funds to clear 📦 Finalize quantities 🏭 Coordinate everything with the Chemical Plant laboratory ✅ Submit everything before the holiday begins ⚠️ Please do not wait until the last minute. 🌐✨ NEW ORDERING WEBSITE — MONDAY, SEPTEMBER 14 Our new Group Buy & Individual Buy website will be ready Monday! 🎉 The process will be much easier: 🛒 Place Order ➡️ 💳 Submit Payment ➡️ ✅ Payment Confirmed ➡️ 📋 Order Processed Previously, we spent a lot of time manually creating and sending invoices for orders that were never paid or completed. ⏳ The new system will allow us to focus on confirmed and paid orders, reduce unnecessary back-and-forth, and keep everything moving more efficiently. 🙌 🧪📦 CHEMICAL PLANT TESTING & SHIPPING ⚠️ Please understand that Chemical Plant operates differently from our previous lab. The Chemical Plant laboratory conducts in-house testing before products are sent to clients. Their testing, shipping, and tracking process may look different from what you were previously accustomed to. ⏳📦 ESTIMATED SHIPPING TIME: 4–6 WEEKS Please plan around an estimated 4–6 week shipping timeframe. 🙏 We are doing our best to improve the process and reduce shipping times whenever possible. If we can get shipments through faster, that is always our goal.

@Moon Pahlavan this is what I want to know too. If people are pooling together for a group by it seems like a great option to test for things like endotoxins, especially on more commonly bought product. I’ve been searching all different Skool platforms and people just don’t group test. It doesn’t make sense to me.
✨ GROUP BUY FAQ — HOW IT WORKS ✨
👥 What is a Group Buy? Everyone’s orders are combined into one large order. This allows us to receive wholesale pricing that you normally wouldn’t get when ordering by yourself. Please remember that this is a Group Buy, so the process is different from placing a regular online order. ⏰ When does the timeline begin? The clock does not start when you place your individual order. The timeline begins after the Group Buy closes and the last order and payment have been processed and verified. We must wait until every order is complete before submitting the final order to the labs. 📋 How does the process work? 1. 🛒 Everyone places their orders. 2. ✅ We process and verify all orders and payments: Approximately 2–3 days. 3. 🏦 We wire the full payment to the labs: The transfer and payment clearance on the lab’s end normally take 2–3 days. 4. 🧪 The labs process the complete Group Buy order: Approximately 2 days. 5. 📦 The labs prepare everything for shipment: Approximately 2 days 6. ✈️ The order is shipped: US and Direct International transit is approximately 7–10 days. 7. 🏠 Warehouse Option: After the lab ships to a US Holding Warehouse (7-10 days), the warehouse waits for the rest of the Group Buy order to arrive before dispatching individual packages. Once dispatched, delivery within the US normally takes 3–4 business days. Please allow approximately 4–6 weeks or less for the entire Group Buy process. This is an estimate, 💵 How much does it cost to join? There is a $20 fee to join the Group Buy. 🧪 What is Chemical Plant? Chemical Plant is a lab that works directly with Research and Development. The best part is that these are real, legitimate labs that TPLH has personally visited. Access to Chemical Plant is exclusive to our TPLH Premium members as one of the special benefits of being part of our Premium community. 💎 🔬 What is Lab 2? Lab 2 is one of our trusted and vetted vendors on Telegram. We have been working with Lab 2 for a while and reviewed the vendor before sharing them with our group.

Wondering do folks that team up for these order also do 3rd party group tests like endotoxins etc?
Good Morning TPLH - COA follow up
Yesterday I asked: When you look at a peptide COA, what’s the first thing you check? Now let’s break down some of the important things a Certificate of Analysis can tell you — and what it doesn’t tell you. 1. Identity First question: Is the compound actually what the label says it is? Depending on the testing method, identity may be evaluated using techniques such as mass spectrometry. A purity percentage alone does not necessarily establish identity. 2. Purity HPLC (High-Performance Liquid Chromatography) is commonly used to evaluate peptide purity. You may see results such as 98%, 99%, or 99%+ purity. Remember: purity describes the proportion of detected material represented by the target compound under that analytical method. It does not automatically tell you how many milligrams are in the vial. 3. Quantity / Peptide Content This is different from purity. A vial can test at very high purity and still contain more or less peptide than the amount stated on the label. Look for testing that actually evaluates peptide content or quantity, when available. 4. Sterility & Endotoxin Testing These are separate tests from purity and identity. A standard HPLC purity report does not prove that a sample is sterile or establish its endotoxin level. If those characteristics are being claimed, look for the appropriate separate testing. 5. Lot or Batch Number The COA should be traceable to the specific batch or lot it represents. A beautiful COA isn't very useful if you can't determine whether it corresponds to the actual batch being discussed. 6. Testing Date Check when the sample was analyzed. Testing dates help establish when the reported results were obtained. 7. Testing Laboratory Look at who performed the analysis. Ideally, the laboratory and report should be independently verifiable rather than relying solely on a screenshot supplied by a seller. THE BIG TAKEAWAY Purity ≠ quantity ≠ sterility ≠ identity. They answer different questions and may require different analytical methods.

@Tammy Giauque I’m sorry, my first day here and trying to get things straight. So the Chem lab is a US based lab? I’d assumed these are all gray/China based products.

@Tammy Giauque But 503 labs are US labs rated by the USDA… this doesn’t make sense to me.
