I don't know how they can mes with quality when it all disolves into the oil. If it was cut with something it would have to be an oil soluable cut that was exactly the same color.
GRAPESEED - my soruce for this stuff sells what looks almost green. I don't know how people will respond to green oil when they are so used to practically clear yellowish colored stuff.
Its not difficult for a chemical manufacturer to provide you with something that looks similar to your product that is also partially soluble in oil.
Research supply.net also sells cottonseed oil. If there is an issue use it.
OILS
Cottonseed oil:
Cottonseed oil is a waste product of the cotton industry, so it costs the food manufacturers next to nothing to procure a plentiful supply. The only problem with this is that cotton is not a food crop, therefore is not subject to the same restrictions as to pesticide and fungicide levels. In fact, cotton is one of the most heavily sprayed crops in the world. There are quite often toxic levels of pesticides and fungicides left over and Im not willing to bet the filtering gets it out. It is light in color and fairly thin. This oil is commonly used in pharmaceutical grade gear again due to its price and availability.
Grapeseed oil:
Grapeseed Oil is by far the best IMHO. Aside from the information I gave about cottonseed oil, Grapeseed oil is fairly thin has a low risk for allergic reaction and has a number of additional side benefits which include...3,6 and 9 unsaturated fats. Linoleic acid for example. Grapeseed oil also contains Antioxidants and an additional compound that I found quite interesting. Resveratrol. well known for its heart-health and life-extending benefits is also an Estrogen blocker. Because of its unique chemical structure which binds to the estrogen receptor, thus blocking estrogenic activity, it has the ability to increase LH and FSH. The estrogen modulating effects of resveratrol have been proven to dramatically increase testosterone levels, fertility, and erection strength in several animal studies, without any side-effects. Other research with resveratrol has uncovered its supportive role in healthy blood vessel function. Grapeseed man... Grapeseed oil is generally green in color with a low viscosity. This in my opinion is the choice for homebrewers and kitchen chemists.
Soybean oil:
Most people have not used this product but I hear good things. Here is a study I found where soybean oil was used as a vehicle for injectable testosterone with good results.

Résumé / Abstract
Testosterone undecanoate (TU) dissolved in soybean oil was developed in China to improve the pharmacokinetics of this testosterone ester in comparison with TU in castor or tea seed oil. As a pre-clinical primate model, three groups of five castrated cynomolgus macaques received either a single intramuscular injection of 10 mg/kg bodyweight TU in soybean oil, in tea seed oil, or in castor oil (equals 6.3 mg pure T/kg bodyweight for all preparations). Testosterone, estradiol, luteinizing hormone, and follicle-stimulating hormone as well as prostate volume, body weight and ejaculate weight were evaluated. After injection supraphysiological testosterone levels were induced. There were no significant differences in the pharmacokinetics of the three TU preparations for testosterone and estradiol. The gonadotropin levels showed a high individual variation. Prostate volumes increased equally in all groups after administration and declined to castrate level afterwards. The results suggest that TU in soybean oil produces similar effects as TU in the other vehicles. This study in non-human primates provides no objection to testing of this new preparation in humans.
