You've been reading self-reports of Vets doing subq and being fine. The reality is this will leave you practically crippled and probably sick as a dog from "test flu," a phenomenon that occurs when you first self-administer very high dosages of test, especially high concentrations.
A personal anecdote: my first foray into AAS was pharma sustanon. The long ester alone done into the quadricep crippled me (I was literally hobbling around for a week+) and felt like I had the flu.
The body quickly adjusts, but the problem with what you propose:
- too high a concentration
- too high a dosage
to start
I also think
- subq is for intermediates, much better in practice to get used to a deep (ie comfortable with a 1.5" pin), steady (hands not shaking) injection into the gluteal, ventrogluteal, and deltoid musculature on a rotation in that order
before doing this with a leur lock or insulin syringe.
