This is my first purchase for research purposes and I'm feeling overwhelmed - information overload! Narrowed it down to three suppliers (I think): SRY, QSC, Nexaph. Need the supplies delivered to Boston, MA by November 5th at the latest.
Unfortunately, SRY and QSC are out of stock at their US warehouses. QSC will have availability in 2-3 weeks and the price last week was $270ish with shipping. SRY can ship from China for $230 inc shipping, but I'm kinda worried about packages being delayed or rejected at customs. Nexaph has new stock in the US, but I don't think there are COAs for the new batch, I think I saw something about sterility issues(?), plus it's $340 inc. shipping.
Have I identified the best options, or is there another supplier you would recommend? I am only interested in 30mg Tirz and guaranteed delivery in the next couple of weeks.
Thank you!
