Introduction
Geneza Pharmaceuticals GP Deca 250 is marketed as containing 250 mg/ml of nandrolone decanoate and is presented in a 10-milliliter vial. To verify its label claims and ensure product transparency, AnabolicLab procured samples of GP Deca 250 from a European-based authorized reseller and internet source, subsequently submitting them for independent laboratory analysis.
The analysis, conducted by SIMEC AG, revealed that GP Deca 250 contained 240.38 mg/ml of nandrolone decanoate—96.15% of the declared dosage. While the product slightly underperformed compared to its label claim, the results affirm the importance of independent testing for quality verification. The analysis and sample submission were funded by AnabolicLab to promote transparency and harm reduction in the anabolic steroid market.

I’ve been using GP Tren Ace after checking lab test results here. I notice the oil is very yellow – presumably they make it from Finaplex pellets not Chinese powder.
as popular as it is I doubt they would use pellets because the extraction process on a large scale would be daunting and quality control would likely not be consistent without raising eyebrows than to just go with direct powder that has no estrogen or fillers to remove
Finaplix H doesn’t contain estrogen. I’ve never seen tren ace that wasn’t yellow oil made from solvent extraction / filtering of finaplix pellets. I’ve seen tren ace powder advertised in China but never come across it. Not sure if it’s even manufactured by UGLs as finaplix extraction is cheaper and easier.
This is the dumbest thing I have heard today. Do you really think these guys are sitting around extracting fina pellets. Haha. GP mass produces 100,000 vials plus at a time. Do you understand how many fina pellets that would be and how expensive it would be to do that ??? And this is a deca test ? They use Chinese powder. They test all their Raws before they start production due to an issue with test e from a few years ago.
I’d love to see a lab test of recent GP Halotestin and Winstrol. I’ve got some stashed away and will use one or the other in a few weeks at the end of current cycle.
There seems to be a boatload of Cooper Pharma Deca on the market these days, any plan for this?
