A doc absolutely will NOT prescribe SERMS (or jack) if you go in with 'blah blah PH.'
$3 for 10x 20mg is not too god to be true. It is a cheap generic drug - hence no fucking need to go to a research chemical place.
The neccessity of a prescription is NOT necessarily the responsibility of the company, but yours.
If a pharmacy operates from a country where it is a prescription only drug, they cannot legally sell it without a valid prescription being seen.
If the pharmacy operates from a less regulated country (as per the example you saw i suspect) then while they can legally sell the drug to anyone, you cannot legally buy in FROM WITHIN YOUR COUNTRY without a script.
If you as a US citizen went to that country, you could do so - but you would not be able to bring it back without the script.
This is the reason many US citizens will go to mexico for just a few hours each week - for a shot of T and Nandrolone. Less than ideal but common.
