+ 1 Short Esters and PIP
ad
I’m currently running my 3rd cycle, Test C 400 and Mast P 300 a week. 1st was just 300 test and 2nd was 350 test c and 300 deca. The mast is from a reputable source on here.
Finishing up my 1st week and the mast p is killing me with PIP. I’m injecting 133 test c and 100 mast p M, W, F. Using a 25g 1 inch needle in glutes. I’m around 12-14 percent BF.
Other than having my wife’s boyfriend do the injections, any advice on reducing pip? I have 3 more vials to work through.

Turns out I’m just a pussy. Heated up the mast some and no more pip. Thanks for the input everyone.
Lots of good info given in previous posts. Typically reasons for PIP are allergy to a carrier solvent/solution , contaminants or gear is starting to crash / has crashed. Try the compounds individually , my go to supplies are 25Ga 1” or 5/8” depending on where I’m pinning. Anymore i only pop the 1” for lats and glutes & 5/8 everywhere else. Hope you get it figured out and comfortable man.
Appreciate the insight! I might try and heat the oils up a tad tonight see if that helps at all.
I've been using a test mix 250 & NPP 150 using a 23 gauge. Did see NPP tested at 203mg. Glute be killing me for days with a knot in it. Don't know if it's age, but seem to be more sensitive to solvents.
I only swapped out the test mix for test E now with NPP and it's been painless since..
Same carrier oils?
Yeah both MCT. Maybe a bad injection, but im gonna try a little less volume and a smaller needle.
I mean you can try less volume but it doesn’t change what’s in the syringe that is causing the pip. Less volume but still same concentration of compounds.
I’ve also personally found that smaller needles in certain areas cause some irritation in the form of a small mosquito like bump.
I think someone suggested injecting them separately in different places to for sure know which is causing pip. I do this on occasion when using a carrier oil I’ve never used or just to see how I react to a certain compound when it’s injected by itself.
I like to rotate injecting each testicle. They are kinda hard to find at this point but I just let it rip
Stop using a fucking harpoon to inject
Hahaha I feel like 25 is pretty small. I’m gonna order some 27s.
I use a 23g most of the time.
Ya but you’re just a psycho haha
I do use 27g on upper body injections so only half psycho.
I’m giving you a thumbs up for the “wife’s boyfriend” joke hahaha
Not to insult your intelligence, are you sure it’s the Mast? I’d pin one compound in one delt and vise versa.
That or pin daily so you don’t have to take so much volume, draw from the same vial, then rotate between delts and glutes. Other dudes talk about chest, fuck that.. I saw a post today about calves.. um.. no hahaha
The guy that did the calf injection is too good. Severe tactical error.
No offense taken. I’ve just been cruising with this test and then added the mast p in this last week and now I’m dealing with PIP. Appreciate the input!
Mix a weekly dose of the test and mast in a sterile vial draw up daily and pin with 29 g 1/2 inch needle. The less volume and cutting the mast with the test should do the trick. Also will need to rotate injection sites if you are just pinning your glutes.
Thank you for the input. I’m thinking moving to daily injections is probably the 1st thing I’ll try.
I rotate Lats, delts, chest, and quads.
All my 1 ML injections- L Carn, PWO, Amino Blends goes into glutes
