Looser waistband
Right vial, fast delivery, waistband is looser. Good enough.
Tesamorelin 10 mg
Off-white puck, lot matched, purity line above 99. Shipping was a normal three days from Phoenix. Nothing else happened, which is what I want from receiving.
Not what I ordered
I ordered tesamorelin and got something else in the mailer. Support checked the pick list and sent the right vial. No runaround. I'd rather it had been right the first time.
10 mg, paperwork checked out
Needed tesamorelin for a run we already had scheduled. COA HPLC was above 99, the 10 mg on the label was the size we ordered, and the powder wasn't smeared up the glass. Came out of Phoenix and was on the bench in three days.
20 mg tesamorelin
Reconsituted clear. COA was above 99 and the lot matched. Cake had been a normal puck before I opened it. That's enough for me to release it.
Wrong size in the box
They sent a different size of tesamorelin than I ordered. I sent a photo of the label. The right one was in a new box two days later. The mix-up is why this isn't higher.
20 mg tesamorelin
Larger of the two sizes. Lot matched, HPLC above 99, cake off-white. We use it as a research reagent and the paperwork was enough to file.
Independent laboratory testing confirms purity and composition of this Tesamorelin research material. Each lot ships with an authentic, batch-matched COA.
