Before I mention the supplier, I'd like some feedback...
I ordered PT-141 and Melanotan II. Haven't tried the M2; intend to wait until summer. As for the PT141, my first dose was 1mg. 100% certainty of accurate dosage and proper injection. No results whatsoever. Waited 24 hours; tried 2mg at a different location. Nothing. Waited several days; tried 3mg at a third location. Nothing. I've got 4mg left, and am tempted to dose it all as a last-ditch effort, but at this point I suspect that I've been sold fake product, and won't be surprised if, come summer, the M2 shows no aphrodisiac effects either.
Have you tried PT-141 before?* The biggest dose I've ever taken was 1.5 mg, and that was mainly because I was developing tolerance.* If you've never taken it before I'd think that 2 mg would be plenty.
I would hesitate from the conclusion of being ripped off, particularly when the idea of injecting 4mg of peptide (or snake oil) is a current thought - advice would be to not attempt a mega-dose with a product that has not been delivering & contact the supplier. The comparison/experience with Melanotan II should be interesting & look forward to update!
I also don't think you have been ripped off. But, since this is not considered a controlled substance and is considered a research peptide...there is no certainty as to how pure some of these peptides are (unless you fork over $$$ to test peptide levels independently).
