Yes, your body doesn't agree with the carrier oils used. I had to toss a vial of tren lately because it was suspended in miglyol oil and caused unbearable PIP. Grape seed is where it's at, but could be "dirty gear" as others have stated as well.

Better off tossing it and not returning to whatever brand you bought.

I had a buddy going for his IFBB pro card about 18 years ago he lost the most lateral head in one quad due to dirty gear. THe" Gear Flu" doesn't hit some people that hard...it freakin buries me. I did a quad shot 15 years back and had to have almost 200cc drained out of my quad with a 4 inch 18 guage pin at my Docs...it was over two sessions and I had IV, IM and oral antibiotics. I always keep antibiotics on hand. The other thing is if I am using a new product or a new source saying I can't use dirty gear plain and simple and each source normally knows if they have a product that causes problems...that product just isn't for me so please don't sell it to me as I will be looking for a refund. I am old enough that when I started there where no "underground" labs...everything was expensive but from a Pharmacy whether in the US, Europe or Mexico. In fact you could open a Physicans Desk reference at the local library and look up your meds with detailed descriptions, lot nuumbers and photos. Kinda miss those time

Do you have a sore throat, fever, body aches and other general flu like symptoms? If you do you have an infection from dirty gear. Is the injection site itself hot to touch?

To test the gear try a 1/2cc inj into your delt...of course use real solid protocol when it comes to giving yourself a sterile shot...but if you have neg effects from a 1/2 cc shot you have dirty gear. you can through it out or try the old bake at 160 degrees for 20 minutes out a small pin like a 25g in each vial to provide a vent while cooking. Let me know if you need some help I can walk you through this. But if you have been taking I am guessing Watson brand Cyp from your Doc for a year with no problem...most likely the gear. Its not like this is your first time injecting. Keep me posted.

I'm surprised that there's no mention of site rotation or questions about needle size. Glutes are the least susceptible to pip because there are less nerve endings. Even pinning twice a week without site rotation there can be significant damage and scar tissue. If you changed sources there may be more ba or bb that can create more pip. Like rusty said read and read some more. The more information that you can arm yourself with will make your guess an educated guess. The most important will be proper sterilization and pinning technique. Good luck bro and let us know what you come up with. Even long term players are constantly learning. Oh yeah I almost forgot..... Don't post the source here. Take it to the SI pages and/or the reviews. Don't wanna get dinged for not using the proper channels.....
