Need some history on you Sir.
Age
TRT or recreational use ?
Cycle history--- is the first time...is it trt ? Using a 1.5 inch needle, if your burying it to the hilt should not result in these sized bumps unless this is ur first time and ur body is not into u stabbing yourself then introducing an oil deposit into ur ass.
Is it HG test or UGL ? I DO NOT WANT TO KNOW WHAT LAB, just answer the question. Diff lab s use diff oil and there s an outside chance that particular vial/vial s and u are not compatible.
FYI-a 1 cc, 250 mg pin is not the issue. That concentration is fine but something s amiss if your getting lump s of that size w 1 cc.
