Can't specifically comment on aPHP. But I have dosed MDPV and aPVP orally before, once each respectively. My aPVP oral dose was a roughly a ~10-12mg crystal chunk. Weighed it out as such, but I always give or take a couple mg with my scale just in case. I was dumb and I put the raw crystal in the mouth, got some water and tried to swallow it. Let's just say it got stuck and took about 10 minutes to fully dissolve away into my stomach. That was HELL. My asophagus was on fire and was swelling up, felt like I was going to need to call the ER. And then when that subsided my stomach got a little upset, but only for a moment.
I had already been binging on the stuff for a whole day, and that crystal that I swallowed got me going pretty nice for about 40 minutes before it wore off and I went back to vaping/snorting. Without any tolerance, I'd guess it would have had me going for a couple of hours on a good one.
THAT SAID if you really want to go through with this I would follow these steps:
1. First and foremost see what the consensus is about the quality of your vendors batch. And always do a few allergy tests before diving into any drug.
2. Knowing the general idea of batch quality of your PHP, read the mega threads and scour the internet for a dose to dose ratio for aPHP to aPVP. I would start low. So if (and this is pulled out of my ass) 15 mg of aPHP = 10mg of aPVP I would start at like 6-8mg of aPHP to be safe, and that's AFTER the allergy test remember.
3. Put your dose in a gel cap or at the very least parachute it. Don't do it raw like I did. I was being a dumb ass and I paid the price. I would wager my next paycheck that aPHP is similar is caustic-ness to PVP.
Side notes (keep in mind I have yet to try aPHP, but have heard a deal about it):
-aPVP rapes my nose and septum. 4 days of snorting small amounts of aPVP did more damage to my septum than 2 years of daily 2-FMA snorting. Buyer beware.
-Vaping is the choice ROA for these chems because they hit fast, and produce a solid amount of euphoria. When snorted or taken orally, its just not much of a fun time. MDPV/aPVP/aPHP are not daily use drugs. You will die before you use any of these chemicals daily for 365 days, either that or end up in the looney bin.
When done safely and in small amounts they are a fun time for a day or two! I honestly always prefer vaping, but since you're new to it oral is a good start. Plus I hear that vaping aPHP is extremely fiendish, more-so than even MDPV because of the short duration of action.
And make sure to brush your teeth and start small! You don't wanna wind up thinking your neighbors are out to kill you after your first dose, because you didn't accurately weigh it!
Peace!
