Good Morning/Afterrnoon or Evening Evo family,
Just wanted to share my experience and hopefully get some feedback/reinforced clarification
Current cycle
400mg/ml Test E from @Gold Standard Labs
100mg of Tren E from @ODINLABS (old vendor)
6iu of HGH from @Prymal
Injection protocol
Test 1ML injected once weekly
Tren 0.5ml injected once weekly
HGH 60iu before bed
My dimensions
28, 5’7, 86kg fasted at 18% bodyfat
History
TRT 2022-2025
250mg Test E (various vendors) Jan 2026-April 2026
Now that I’ve set the scene, I feel pretty embarrassed as a Dr (2nd year resident) to have experienced some pretty debilitating PIP from the test injection.
Last week, Wednesday, I pinned 0.5ml of Tren E 200mg, IM into the right lateral delt using a 30g needle, warmed the oil, injection took just under 20 seconds. No issues, knots or pip for the last week. Injection has been fine and haven’t had an issue.
However I replicated the same process for the Test E, 1ML through a 30g needle (not slin pin), IM into the left delt, oil warmed, injection took just under a minute. Within the first 24 hours there some slight pain from the injection, which rapidly grew over the next week. After 48 hours it was tender to the touch, couldn’t sleep on it, lateral movement of the shoulder was painful, overhead pressing was extremely difficult.
It took almost a whole week post injection for the pain to recover, using nurofen daily to reduce the pain.
Now my medical understanding believes that because of the concentration at 400mg/ml, plus the increased used of solvents, the post injection pain was more severe.
Initially I was thinking the injection was too shallow using the 30g, however I had no issues with Tren Injection so I don’t think needle length is the issue, however I can go to 27g 16mm if necessary, I just hate needles
.
i also thought that maybe the lateral delt couldn’t hold the volume, but at 1ml I believe that’s ok as well.
So presuming that it lies with the oil concentration, split dosages would be the best bet, so my question(s) would be:
Should I split the dosage to E3.5 days 0.5ml 200mg or would I run into the same issue? I was thinking about using the ventroglute and lats if needed
Would I also run into the same issue regardless if I used 1ml into the ventroglute, given the muscle has more volume to hold (3ml) the oil may better disperse more?
Thankyou all for your time and help in advance, it may seem really dumb and probably an obvious solution but as I take the next step in growing I want to be as certain as possible
