In all honesty man I'd do as the others said and just supplement your other prop shot with that stuff there.
What concentration is the other prop you were gonna add it to? If that's a 15ml vial @ 100 mg/ml its roughly 13-14ml solvent and about 1.5g of powder, not sure if thats gonna help much other than to draw up the oil in the vial and see how close you are to that number assuming its all solvent/oil and the prop has seperated.
Thats a 10ml Vial @ 100mg/ml. I have another vial exactly the same (though i took a couple of shots from it). My plan was to crash all the Prop from BOTH vials, then re-mix them in the oil from just ONE vial, i.e. doubling the ammount of test.
Once again I don't know the concentration you have for the other prop but if you go adding the crystals to that you run the chance of having that crash with the higher mg/ml (unless the carrier is EO).
Even if it kept crashing, could i not just warm it up every time?
Overall its gonna be a big pain in the ass and you're not gonna know what your final concentration is. How much can the stuff you're crashing be underdosed? Why not inject the other stuff as the minimum test you're taking and add the other stuff in addition?
Yeah i hear you. I'd guess its underdosed by close to 50%, i.e its more like 50mg/ml though obviously Ive no real way of knowing. Obviously I can just shoot twice as much as I would have done, but I still have the same problem of not knowing the final concentration...I thought if i crashed it and showed you guys some pics someone could perhaps estimate.
