Hello,

I am sending over new test results for your review and would like to invite you to re-evaluate and reconsider our premium range offer.

We look forward to your feedback :)

PS -Additionally, I am also sending substance test results for your review, to show that we control the entire process from the very beginning. We do everything from the base ingredients and do not use pre-made compounds—we create the final product ourselves.

Thanks for sharing the updated testing. The finished product assays look good, but I’m more interested in the consistency and reproducibility over time than a single set of results. It’s also good to see you’re providing raw substance testing if you’re claiming to control the process from the base ingredients forward. The more transparency—multiple batch results, COAs, and independent testing—the more confidence people will have. Looking forward to seeing everything you’ve atta

My thoughts as well. Would you even use 83% raws if that’s what you received?

That depends if it can be filtered properly. As long as it's filtered properly, the impurities will be removed from the solution. The more impurities, the more difficult it is to filter. I've had 83% pure test e and it went in the garbage because it couldn't be filtered.
 
But you cant filter something thats dissolved in solution. So 17% mystery substance. Maybe some is particulate and gets filtered, maybe god knows what that dissolved in the brew that passes through the filter and into the body. My point being there is no data from that test saying what that 17% is.

That’s a fair point. A potency assay alone doesn’t identify what makes up the remaining 17%. It tells you the API content, not the identity of everything else in the vial. That’s why tests like residual solvents, endotoxins, sterility, heavy metals, and impurity profiling are important—they help characterize what else might be present. Without those, neither side can say with certainty what that 17% actually consists of.

Yessir, and if the math is done to account for the % difference to get the correct mg dose youve also increased the level of said impurity per mL as well.

Masteron came back a month ago, so this batch has stayed consistent the whole time. It will take a while to go through it because the stock is quite large, but as always I will keep uploading control tests, just like I did with Primo and the other products.

Hi,

everyone on the market received the same raw material 🙂 that’s how this batch came out — there wasn’t a different one.

The percentage refers to the composition of the product in the solution, not contamination levels.

That’s why I also shared it for full transparency and review.

That’s not really how it works — it’s not an “unknown substance.”

Active compounds of this type are created from specific reagents that are constant, so no new chemical component is formed. It depends on the synthesis recipe and the conditions, which is why different batches can show different percentages.

Clearly that’s not true. Another sponsor literally just posted their Mast E raws test that came out at 98%+

Maybe this is a different supplier, although it surprises me a bit — I know how this market works. There are not many manufacturers in the world focused on this type of substances.

A result showing 99% active substance purity is impressive. In my 22-year career, I’ve only seen something like this once, and it was 98%.

What the hell are you talking about?

You think there’s only one place in the world synthesizing raws? This makes no sense

Please show me where I said that there is only one place producing the raw materials. I never said that.

What I said was that there are very few manufacturers producing the active pharmaceutical ingredient (API), especially for compounds like Drostanolone. So please don't put words in my mouth or make assumptions when you don't have knowledge of this particular market.

Drostanolone has not been a registered medicine for many years, and as a result, it is no longer used in modern medicine. Of course, I'm not talking about countries like India, where patent laws and regulations are different and many manufacturers can produce various compounds more freely.

This drug disappeared from legitimate medical use a long time ago. Because of that, its production is no longer part of the mainstream pharmaceutical industry, and the available supply is primarily intended for the underground market. That's simply a fact. Anyone who has been in this business for a long time knows exactly what I'm talking about.

Just because someone pours or processes a raw material into finished vials doesn't mean they manufacture the API itself. Those are two completely different things, and that's a fact
 
Please read the entire post carefully and try to understand the full context, not just a small part of it.
