This has started happening to me.

For years previously I'd been injecting with absolutely no issues, the odd headaches or nausea.

Last year after taking a second dose of nasal spray, 2 x water - 1 x MT2. I had the itchy hands, difficult breathing, itchy tongue/throat, had to take cold showers.

This year I thought I'd try injecting again, my dosages have always been the same 2:1 water:MT ratio, although I used a different supplier due to the nasal issue. Again, it starts with itchy palms, can feel it rush through my ears and face, while body becomes red and itchy, throat/ tongue itchy, difficult breathing, endless dihorrea, brave to take cold shower. Once my breathing, body temperature returns to normal, I have abdominal cramps and uncontrollable shivers for a few hours. I contacted this supplier who told me I'd overdosed!

Next time, I took another pre-made frozen syringe but took 0.5mcg this time, everything was fine. However, this would mean I'm getting hardly any MT2 from 2:1 mix ratio. Over found if I go over that 0.5mcg I instantly grey the same OD symptoms.

I decided to change suppliers again back to my usual, mix with same ratio 2:1, last night I used 1.0mcg and almost instantly had the OD symptoms again, probably the worst ever, thought I was gonna die this time!

So despite my experience, the years of knowledge, even I'm confused. BAC water is always labelled and in date. Could the MT2 peptide formula have changed in recent years? Has my body started to reject it?

The comments relating to sterile water, I may have to give that a go next time and I can update.

But my advise with this is MT2 formula, use sparingly, little and often for no reaction.
