I wouldn't either UGL in both of those pictures, they both have extremely mixed reviews.
I'm not going to comment on whether it not you should run Clenbuterol as I have no knowledge on the compound, nor do I intend to.
If the other knowledgeable say it's a good idea then I would definitely use
Ar-r.com or
purchasepeptides.com for your supplies. Their products are sold in liquid form and rendered as 'research chemicals', thus making them 100% legal in most countries. Seeing as you live in the US it's unbelievably fast shipping with a close to zero chance of your package getting seized.
Good luck bro!
