Hello, I am looking for any information or research regarding peptides which help to combat parkinsons and its associated symptoms. I've primarily interacted with the weightloss side of peptides so even basic help would be appreciated.

its the positive charge that filters the endotoxins, how high a level not sure yet. But they are specifically designed for filtering endotoxins

@ResearchCat That's a very creative and GREAT idea! I'm gonna try it! Thanks!

Thank you, Randy. Speaking for myself and probably a lot of others, we spend quite a bit of money and time to keep ourselves and others safe. Then there's a few bad apples who find ways to look accountable while behaving fraudulently all in the name of getting that mighty dollar. This really tarnishes the industry and unfortunately, only plants more doubt in an already difficult industry. I work hard and so do many others to be transparent and provide honest and accurate paperwork. Then people like this come along.

Did you send the Reta and Tesa out for testing?

I know its not suggested, but I take CJC/IPA at night and Tesa/Ipa in the am. Both in a fasted state. The Tesa at night left me with several sleepless nights, and the warm rush from CJC is dreamy.

Hi guys. Any recommendations of vendors inside EU?

Theoretical Synergy- Can BPC-157 and TB-500 work even better if you supplement L-citrulline, L-arginine, and dietary nitrate sources like beetroot extract to boost Nitic Oxide (NO)? These nutrients provide the raw building blocks your body uses to synthesize nitric oxide, supporting blood flow and circulation even at the capillaries level.

Thank you

Yes, https://peptide-works.com They sell vials and nasal spray form; I wouldn't get the nasal spray again cuz the mg amount isn't noted so I had to figure amt from iu/mg estimate and it looks like I would need 15 sprays for an effective dose.

Peptide quality involves more than simply confirming purity and molecular weight. A peptide’s amino-acid sequence, stereochemistry, chemical modifications, folding, and ability to adopt the proper three-dimensional conformation can all influence how effectively it binds to and activates its intended receptor. Problems such as D-amino-acid substitutions, sequence errors, oxidation, aggregation, or incorrect disulfide bonding may reduce biological activity. Common testing such as HPLC and LC-MS is extremely valuable, but it has limitations. HPLC primarily measures purity, while LC-MS helps confirm molecular mass and identity. These tests do not directly demonstrate that the peptide binds its receptor or produces the expected biological response. A product could appear highly pure and have the expected mass yet still possess lower-than-expected potency. “Biological availability” is sometimes used to describe this issue, but “biological activity” or “potency” is more scientifically accurate. I would love to see Peptide Critic conduct a blinded experiment using products purchased randomly from several vendors. Each sample could receive the usual HPLC and LC-MS testing, followed by an appropriate receptor-binding or cell-based functional assay. Testing the pharmaceutical reference standard alongside them would make the comparison especially meaningful. This would help answer an important question: Do products that pass routine purity and identity testing consistently produce the expected biological response? Even a small pilot study could provide valuable real-world information and show whether additional functional testing should become part of independent peptide evaluation. Charles River Laboratories. They specifically advertise cell-based functional testing for GLP-1, GIP and glucagon receptor agonists, including measurements of potency and receptor selectivity—an especially good fit for retatrutide or tirzepatide.

Before any one ask, I am not affiliate lol If you go through my post history, It's obvious I'm a pretty big supporter of Nexaph / EZP and occasionally Crush. Though, I did make my first purchase with Puratek, which I will review soon. I'm sure like others, I like finding a decent deal with resellers since I'm not 100% with going grey just yet. Anyway, ZCLabs has decent deal with 20% off with the code ZCLabs20 & with the Code Stockup for a buy 3 and the 4th vial free. Also with every purchase you get 100mg GHK. My rat doesn't do well with GHK, so I was able to email the vendor and he let me choose any product that's the equivalent of the same price, which honestly threw me off guard with the great customer service. So I picked Selank since it's been one of my favorite researches at the moment. The COA is provided by ILS - I was able to confirm on ILS, so it's legit. I know some people are hesitant about ILS but I am not, so I decided to move forward. All in all, I'm receiving (4) 30MG Tirz and (1) Selank for $132 and some change. Are they grey prices? No, but it's certainly better priced than some vendors. I usually get kits from Nexaph, but I always like finding new options for single vial resellers. As proof to my purchase, I added a screenshot of my order. [image: 1786297425468-img_3032.jpeg]

This is a vendor review submitted by forrestdawkins on PeptideCritic.com. Rating: (5/5) Review I have had great success with Peptide Tech. I have only ordered their GLP5 or GLP 3 with Cagri. Works great. Quick shipping if ordered at the beginning of the week. Great prices.

Please keep discussions respectful and factual.

Or am I missing something? Why do all BT labs COAs have such a thing?

I think Disguised Alpha is planning to sell GLPs in these use and throw pens. We are reaching mainstream pharma level delivery mechanisms while the testing is getting sh!ttier with the drama around new labs — so many vendors originally using Vanguard, Jano, or Freedom have jumped over to the new kids.

I was looking at Selank from Mile High and same… 100% purity.

@OldGuy True! A vendor showing a new lab COA on every new batch seems to be a in a hurry to get the batch out somehow than ensuring QC. Now that customers want testing, just a COA for a COA, regardless of authenticity of testing. These vendors often have newer batches but at this point I've become skeptical about the freshness of vials vs quick COAs from questionable labs. Peptidology batches are sometimes older, but they have been consistently using Vanguard and full testing panel even when it was not in vogue. That invokes trust! Not advertising Peptidology, not an affiliate either, but just pointing out clear differences I noted between them and others.

@bangkokiscool Absolutely agreed. When you first start you’re gonna want to see bloodwork every few weeks to see how you’re body is reacting so you can adjust dose as necessary.

@judgetoo this is an excellent resource. Thank you so much!
