  1. Theo W.Verified buyer

    Looser waistband

    Right vial, fast delivery, waistband is looser. Good enough.

  2. Sharon R.Verified buyer

    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.

  3. Farah J.Verified buyer

    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.

  4. Sophie P.Verified buyer

    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.

  5. Darius D.Verified buyer

    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.

  6. Nadia R.Verified buyer

    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.

  7. Neel N.Verified buyer

    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.
