It is not illegal to possess in the UK. It is illegal to sell. I know and I am sure customs knows, too, that companies package substances in a way to avoid taxes and legal complications.
It isn't the name of the product dropping a letter or even "fooling" customs ( there is actually an OTC product called Anavar being legally sold in the USA ) It is the label. My guess is if opened, the package is less likely to be seized if it is labeled as a vitamin or amino acid ( I have had DHEA which was illegal in the Uk shipped from the US where it was legal, labeled as protein powder: I asked the company how they were going to get it to me since it was forbidden here and I did not want to get into trouble and they said don't worry we have "discreet packaging" ).
If you are working at customs and you open a package with a product label : 17ß-hydroxy-17a-methyl-2-oxa-5a-androstan-3 I guess they have to seize it, I don't get into trouble for buying but they do for selling. Whereas if you look at the label and it is a concoction of vitamins/amino acids, how likely is it customs is going to go through the trouble and the money to lab test every single order? If is a gigantic order common sense tells, yeah, test it, for all they know it could be heroin, lol..But one bottle I think customs knows and lets it go by. I know I would. By the same token, if I were working at customs and I were corrupt, upon opening a package of Oxandrolone labeld as such would I not be tempted to seize it AND keep it, think about it...*wink* *wink*
I had all the listed benefits and mild side effects of Anavar and also tests revealed a chemical substance and the lipid, and liver toxicity levels of said substance. So I knew it was chemical but because of the plethora of pharmacological formulations of today I thought it might be a prohormone similar in structure to Anavar - which still may well be, as I said unless I have it tested I will never know for sure.
You don't put on 10kg in 3 weeks and get ROCK HARD muscles and increased strength and intense cardiovascular output on vitamins doing nothing - I am not surprised they give this to cancer patients who cannot put weigh, keep weight on. It is not a fat loss product and for bodybuilding purposes your body fat would have to be low unless you want to gain fat.
I had lost 5 kg of muscle from 4 years of good work due to a year off and illness and I wanted to put some weight back on and regain some strength to kick me start training again and this is what it did for me. It got me back into the gym lifting heavy!
