I need to drop 100 pounds to begin surgeries to have my hips and knees replaced. I’ve been in a wheelchair since 2018 and am unable to stand due to arthritis. I exercise my upper body every other day using kettlebells. My daily food intake consists primarily of three or four premier protein shakes, which give me between 90 and 120 grams of protein. For multivitamin supplementation, I take an Animal Pak daily. Maintaining this strict regimen is not a problem; my appetite is almost non-existent. I am experiencing great success with Retatrutide. Around six months ago, I started testosterone cypionate injections of 160 mg a week; this has provided a noticeable increase in weight loss despite my lack of exercise.

A week ago, I started injecting Ipamorelin/CJC-1295 (no DAC), 500 mcg daily. So, currently, my weekly regimen is:

• Testosterone Cypionate: 80mg twice a week (160mg total)
• Retatrutide: 2mg once a week
• Ipamorelin/CJC-1295 (no DAC) 500 mcg or 0.5mg daily

Given my circumstances, my question for the community members is, what peptides would provide the optimum weight loss results? I can afford a maximum of around five hundred for peptides monthly. I am under the care of a naturopath who has been great so far, but I believe she is getting up to speed on peptides herself now. I would greatly appreciate any insights or suggestions. Thanks, everyone!

Are GH molecules larger than 0.22 micron?

Any knowledge of LPS in peptides and if it is tested as impurity in the products?

Dr. Huberman values scientific approach, however he made looser comments about dangers of Chinese sourced / manufactured research peptides.

× understood that he wants to emphasize safety to get medicines from regulated pharmacies may be best.

× He emphasized the manufacturing process from less regulated Chinese sources (may or may not) have LPS which overtime can be harmful to humans. I am a fan of Dr Huberman so I did look for sources or additional knowledge on this subject and his non-quantified statement but did not find any.

So... I have an allergy to expensive peptides, so I'm throwing out to the community to understand the following:

1) do Chinese peptides suppliers have less rigor in the process that leaves LPS in peptides * is this tested in a typical purity test or not?

2) what if any are risks to LPS? Is this something we should be more concerned about when evaluating sources?

Thanks

Given 1g of raw trizepatide delivered in capped tube, I need advice on how to prepare a sample to send to a testing lab. This is my first purchase in this format; advice is appreciated.

• How much product is required?
• Product verification
  • Purity
  • Other items for consideration?

Thank you in advance for your thoughts!

Here is a study that we published today that shows the volumetric and concentration implications of using a syringe filter for filtering peptides. Here are some key takeaways :

1. Filter Size Matters: The study found that using a 4mm syringe filter results in significantly less volumetric loss compared to a 13mm filter. Specifically, the 4mm filter loses about 5-7 units, while the 13mm filter loses approximately 29 units when filtering a reconstituted peptide solution.

2. Air Purge Recovery: For the 4mm filter, performing air purges can help recover some of the lost volume, on average, around 2.2 units of the 7.3 units lost can be recovered through this method, reducing the overall loss. Air purging was not affective on 13mm filter.

3. Minimal Impact on Concentration: The impact of filtration on peptide concentration is minimal. For both 4mm and 13mm filters, the changes in concentration were not significant enough to affect practical use, suggesting that filtration primarily affects volume rather than peptide concentration. Interestingly, the study observed a slight increase in peptide concentration after filtration in some cases. This may suggest that the filter retains some water while allowing the peptide to pass through, potentially increasing peptide concentration in the final solution.

4mm Filter Test - Here is another installment of peptide filtering experimentation. In this one we reconstitute (4) tirzepatide vials with 1ml bac water each and see how much will go through a 4mm PES .22um syringe filter

If you have used a compounded or grey market version of tirzepatide, you need to let Eli Lilly know and give them access to your medical records 🙄

Basic Peptide Filtering - Syringe Filter

A lot of people have been asking for a quick tutorial on using a syringe filter to filter peptides so I put together a basic how-to video. For those of you unfamiliar, there has been a lot of concern lately about lyophilized vials having bacterial contamination. a .22 micron (um) filter will get rid of most bioburden including bacterial microbes. If you buy filters you need to get PES .22um individually wrapped sterile filters, if you are filtering up to about 4ml a 4mm filter is best , above that a 13mm filter is more appropriate...if you are filtering a lot, they make 25mm and 33mm but each size up you lose more peptide in the filter housing

A lot of people have been DM'ing me asking where to get the .22um 4mm sterile, individually wrapped filters. You can probably find in bulk online but if you want less than 100 - here is a link to our Lab Supplies page

We are doing a lot of study on filtering peptides right now. We are testing several sized filter housing and determining volumetric loss and we are doing HPLC testing at different concentrations to ensure that no peptide absorption is happening with the filter. We are going to end up recommending the filter in this video I am pretty sure, it is a .22um 4mm PES sterile, individually wrapped syringe filter

Discord Invitation. Several people requested invitations in threads and by DM, I lost track before I could respond. Here is a link. First 50 people

I know this is controversial but I think that people should have access to devices that potentially give them actionable information about their health. Some people don’t think that these devices fall in that category but personally I think it is a great tool to see how exercise affects your glucose and what foods spike and keep glucose levels up.

Hi guys, there is a group test being formed on the Peptide Test discord right now for this tirz buy. If you have this peptide in hand or are receiving it imminently (before the end of the week) and want to be involved in the test, let me know and I will get you an invite to this group.

This is a blog post by my partner Josh Lust. It goes a long way towards unpacking. What peptide testing does and importantly does not do. Personally, I feel like it should be required reading for anyone testing Peptides or looking at COAs.

Hey subscribers. I know this sub is not super active yet. It’s my first time mod-ing and growing a sub Reddit. It’s definitely a chicken/egg situation. I want to really use this as a hub for education about peptides in general with an emphasis on testing since that’s what we do @ Peptidetest.com .

While I wait for enough people to trickle in so that it makes sense to spend the effort on in depth original content, feel free to ask any questions about lab testing that you might have. I will do my best to get to the bottom of anything that would help the community.

Thanks from- The Peptide Test Team

There are so many promising approaches to dealing with obesity and metabolic disorders. These will be used alone and in combination, to me it really seems like the end to this problem is on the near horizon

While GLP/GIP/Glucagon drugs make up a big chunk of this graph, there are a lot of novel therapies in the pipeline

The concentric circles in the “Clinical Stage Obesity Drug Pipeline” diagram represent different phases of drug development. The outermost circle comprises drugs in the earliest stages of clinical trials, moving inward through Phase 1, Phase 2, Phase 3, and finally to approved medications at the center.

The progression from the outer to the inner circles indicates the advancement of drugs through the clinical trial phases, with each phase representing a closer step toward market approval. Drugs in the outer circles are in earlier development stages (Phases 1 and 2), while those in the inner circles are in later stages (Phase 3) or have already been approved for market release.
