This my first cycle of injections and my guy got a brand by chaos pharma. It was fine until about 2 weeks ago when I started getting hard lumps on my glutes. They don't hurt at all or red they just hard after injection about 2 days after. Is this brand shit gear or what. I'm using test cyp an deca also twice a week mon/thur. Please any info on this brand wud help.
