Not sure what to tell you. I get a bad reaction from any type of Test P but this Mast P is very mild. Maybe youre allergic or not going deep enough.

Hey Getting, did you have any issues healing up?

Maybe your body doesn’t like the carrier oil

What gauge do you use to pin

How’s the hairline on mast , one compound I want to run but winny destroyed my hairline I just got it back lmao not trying to lose it again .

If you are fat, you need a longer needle, this needs to be Intramuscular Injections. It sounds like you are doing subq or half and half, you need to be in the muscle.

Haven’t had any pip with mater p tne or cyp.

I’m currently only running his oils and have never had a single issue. Even at 3-4 pins a day.

I would be willing to bet you’re just not injecting deep enough. I run 2ML of prop ed and never have any issues. Bare minimum pin for me is 1” for smaller muscle groups and 1.5 for glutes or lats absorbs quickly no issues.

Weak genes

Yeah, what is your experience level with the prop ester? It’s pretty rough in the beginning, but a few runs your primary pin sites. My first cycle was pharma grade test E. I ran it for 12 weeks and didn’t know what PIP was. I kick started my second cycle with UGL test prop and felt like I had a wasp sting in the injection site. 15 years later and I can put a full ML of a oil with a prop ester in a more sensitive site like my delts or pecs and barely feel it the next day.

Another question is how much experience do you have with SRC’s gear? If it’s none/minimal, they may be using a solvent or carrier oil that you have never experienced before that just doesn’t sit well with you.

The 3rd and by far least likely scenario is that they cooked that batch with too much solvent or sterilization agent. It’s happened to me before with other UGL SRCs. HOWEVER- and this is a big however- I’ve been using PA’s gear for as long as they have been in the game and never had an issue. If they fucked up the brew their SI page is going to explode with complaints in the next week or two.

My best advice would be to try switching to lower body injection sites (quads, glutes) and burying the oil with a 1.5” pin.

Upper body sites like delts and pecs are always going to have a higher likelihood of PIP. The oil is closer to the surface and you (shouldn’t) have much fat padding the injection site.

I’d say switch sites, pin deeper and keep an eye on those delts and ensure that they don’t start to turn red and get warm. If they do, get an urgent care ASAP and get some antibiotics.

Keep us posted bro!

Unfortunately sir, some people have adverse reactions to prop.
Even if you had quality prop experiences prior, it really doesn't matter.
Perhaps do not pin shoulders either.

Using his mast prop currently and no brother I do not have that issue. Even doing .5 Mast P daily. Rotating from quads glutes delts an lats
Even half mL in lats an I felt MINIMAL pip. Wouldn’t even consider it pip more like site injection soreness from the needle itself. This shit is great. Also using test/tren 400mg. Thicker yes an only using 10mg.daily still no pip.
Try dilution brother, half an half.

Currently using their Mast p 300mg a week pinning EOD. 1st three injections were rough with pup, but haven’t had issues since. Also been heating the oil before injecting and that’s helped.

Love the Test Have Used it. Many many times before. Lil swelling. But. Nothing out the Norm 1 cc shoulder also have dome in quad gear is. Amazing pip not bad at all

What size needle you using?

This gear is fucking awesome. I’m actually running both of these right now. Injecting every single morning before work. Not a bit more pip than I would expect. If anything, it’s smooth as fuck for what it is. I inject 1/2cc of his prop every morning. Delts handle it fine.
