First time with Double Scorpion

Finally got around to visiting a shop in person after months of no poppers. I noticed they had Double Scorpion Amber and was so excited to try something other than Rush.

To be honest it was a little disappointing but not bad. I'm not sure if the shops stock just wasn't fresh but it didn't feel all that strong and I had just gone at least 4 months without any poppers. I've had a few sessions with it and a session with a bottle of rush as well and honestly they felt pretty close to the same which is crazy because the 10ml of Double Scorpion cost about as much as the 30 of Rush.

Is Double Scorpion just overpriced for how strong it is or is it freshness and rush is just that much more popular that it's stock is always fresh? What's everyone's else's experiences?
