Ghost as Chode stated tren would be bad. I think most AAS would be bad but again if you are dosing them high you might as well site inject (instead of just shooting glutes for example). But your tren a's and test p's are likely going to hurt and cause issues so be careful.
JJ uses huge amounts in his arms. Whilst you don't need to use his amounts you do need to use a fair amount. I would say 2ml+ in your bi-ceps everyday and the same for tri-ceps. That's why syntherol is so good as you need such large volumes without causing major scar tissue and inflammation.
How are you getting on with the primo? I would be injecting your arms everyday. If you are using test too then rotate so primo for bi-ceps and test for tri-ceps then the next day the opposite way round. Both heads of the bi-cep should be used so you can rotate so you never need to inject the same areas daily.
Thanks for the kind words
