Filter Your TRT Ampules

[Zmitmex]

I know this seems basic (and I’m sorry if it’s been covered elsewhere). I’ve been diving deep on here on filtering gear (thank you for @Ghoul for both terrifying me and inspiring me to level up my harm reduction game).

I was first doing research to properly add HGH into my HRT (no cycles here for now) and have been having a little extra pain at my TRT injection sites. Come to learn you need to filter TRT coming out of glass ampules for micro glass shards.

I’ve been on TRT for nearly 2 years, worked with 3 clinics (now buy Bayer Primoteston OTC in Mexico) and none of them mentioned this. So maybe I’ll get a bunch flack for how basic this is but I got a box of BD Blunt Fill needles with a 5 Micron filter in them to start filtering (common practice in hospitals/medical clinic for testosterone). I wish I had of known it sooner (and hoping no permanent damage was done) but if you didn’t know I hope this helps!

If you are working with clinics I assume they are prescribing you real pharma test. Personally I wouldn't filter that.

Each time you break amps, you should filter for broken glass.

Is a filter needle needed to draw from the ampoules? If so, any recommended source in the US?

You should filter for glass.

Eight hundred 10-ml sterile water ampoules were inspected for glass particulate contamination upon opening. Glass particulates were detected in 65% of the ampoules (519/798).

You can't pin with a filter needle just fyi. Much cheaper to break all your amps and use a syringe filter into a new vial.

I've always wanted to try that Primoteston but even from Costco its like $40 an amp.

Filtering after breaking an amp is always good practice.

I’ve liked it a lot! Had 200mg/ml compounded from clinics in MCT and the injection is definitely faster/smoother but for $16/ 250mg ampule I’ll take the transferring process/slower injection any day or the week!

I tried to use a blunt filter needle for Mexican Nebido ampoules, it was really slow and I was getting air bubbles at the syringe/filter needle from the vacuum needed to draw up the thick castor oil formulation.
I eventually just switched to a sharp unfiltered needle. Went through 12 ml with no PIP.

Where do you get the blunt filter needles? My order got rejected by customs twice. I’ve had no pip but don’t want a life time of micro glass to deal with when I’m old.

Ask pharmacies...
It's available easily in US without an Rx..there's no use for it except for filtering glass.
