Now this was funny. Giving me crap and asks this question.if both test 98% isnt it the same quality?
Who is the clown, indeed?

Thank you for your response. So your company goes to the trouble of putting together a USP like C of A but then doesn't go to the trouble of posting them? Why aren't you giving yourself credit for the work performed?Thanks for your question.
Every product has its specification and standard when it comes out. And the standard is different with different products. We manufacture the products based on pharma standards and make ingredient analysis for each batch. And we also make certificate of analysis and HPLC report at the same time. Until confirmation the products meet standards, we sell them in market. Impurity analysis is part of our routine QC program. We only analyze if the impurity is within standard, like 0.5%, 0.1%. As for what the impurity is, it needs separate analysis by specialized machines.
Here is a certificate of analysis for Tadalafil, it shows the standard. And impurities are within limits.
Good day Fellows, I ordered 2 different raw compounds from AASraw. It took 21 days to reach me in Canada.So what is different about AASraw/Aea.ltd now?
1. Stable and Reliable Quality:
• Aea.ltd./AASraw has passed ISO 9001:2015 quality system certification. All the products are strictly manufactured according to cGMP standards and match pharmaceutical grade.
• Quality control covers all aspects, including in-process quality control, batch analysis, warehouse labeling, release control, and batch sample storage.
2. Enhanced R&D Capabilities:
• Advanced process R&D and a specialized pilot plant in Shanghai Juke Biotech Park for rapid developments and early-phase API manufacturing.
• Dedicated to drug research and development, our upgraded facilities in Shanghai boast reactors ranging from 50L to 3000L, supporting custom synthesis of almost any organic compound. We specialize in intermediates, reference compounds, and derivatives of lead compounds
• Our company is equipped with HPLC, GC, and other analytical instruments. Tests can be done on IR, GC/MS, LC/MS, and 400NMR at the SIOC through contract.Once the projects come into our R&D center, our highly experienced chemists will conduct a quick initial evaluation. From first batch sample submission to pilot scale-up and chemistry validation, we emphasize speed without compromising quality.
3. Delivery Capabilities Improvement:
• A state-of-the-art commercial production site in Hangzhou Gulf Fine Chemical Zone, equipped with state-of-the-art facilities, is capable of handling from grams to multi-hundred-metric-ton operations. Ensuring flexibility and reliable lead times for our customers.
We appreciate your continued trust and look forward to delivering unparalleled services in the pharmaceutical field.
Thank you for your continued support of the AASraw/AEA Ltd. company.
For further information, please contact us Email: King@aea.ltd
If customers request it when ordering, we will analyze based on specific needs.
Thank you for your response. So your company goes to the trouble of putting together a USP like C of A but then doesn't go to the trouble of posting them? Why aren't you giving yourself credit for the work performed?
Thank you for the C of A provided. I asked for results from some of your AAS raws. For example, post C of A for a batch of your (1) test cyp and (2) oxandrone raws. Specifically note the assays used for each of the impurity checks (purity, impurity, metals, RS, etc). That way users here get a solid education on what to look for and can indepently verify your results with 3rd party lab.
Why aren't you testing for all elemental impurities instead of just heavy metals?
Why aren't you doing standard residual solvents (RS) assay? Are only those solvents listed because those are the only ones used in the process? Look up the USP reporting options for elemental impurities and residual solvents.
Appreciate your time and you should share all the work to help your business and support verification by 3rd party analysis. Would put you far ahead of competition. Very far.
Thank you for your sincere suggestions and recognition of our quality culture. It can be seen that you have researched a lot about testing of products.And please don't post anymore HPLC results based on area count only. Please assess purity in am accurate way (detected mass of AAS in raw using calibrated HPLC / mass sample).
The proper method requires relative response factor for API using a reference standard.
Thank you.
Thanks for your sharing. Looking forward to further cooperation! Hope we can bring better shipping to you in the future.Good day Fellows, I ordered 2 different raw compounds from AASraw. It took 21 days to reach me in Canada.
What happened to AASraw.com? Disappeared?
Official response: No! AASraw is now also called Aea Ltd.
We are thrilled to share that AASraw (now called Aea.ltd.) has recently undergone a major server upgrade to enhance your experience. In any case, our dedication to quality and innovation remains steadfast.

So you intermittently test your raws for elemental impurities and residual solvents?We don't analyze all elemental impurities and standard residual solvents assay because we confirm that they are within limits and it is not an easy process, which will cost too many sources
The percentage of impurities is different in different AAS. Most impurities are androstadienedione and synthetic intermediate testosterone.Sure my pleasure.
So you intermittently test your raws for elemental impurities and residual solvents?
What is the mean +/- SD (range) weight percent impurity levels on your AAS raws?
Can you describe what those impurities consist of?
Example...
1% side product / raw material
0.25% elemental impurities
1.5% residual solvent
Can you comment if your residual solvent QC approach adheres to USP <467> option 1 or 2?
Thanks!
Thank you for your reply. So what is the mean +/- SD purity for the AAS raws you offer? That should give the user a good summary of the breakdown unless you have a few purities that skew the distribution.The percentage of impurities is different in different AAS. Most impurities are androstadienedione and synthetic intermediate testosterone.
Our residual solvent QC approach adheres to USP <467> option 2.
Thanks for your sharing! Hope our gear make you satisfiedI have two Jano blind tests that I would share
Results are very good
Yes of course.Thanks for your sharing! Hope our gear make you satisfied
