Test only. Go 1ml of whatever you buy (200 or 250 most likely). Your first cycle should be solely to understand how your body reacts to exogenous testosterone (physical and mental feeling, bloodwork, etc.) You can rip 500 but there isn't much of a point; if the cycle goes well you could have just done more next time instead, if it goes bad, you're fucked even harder than if you just did 200 or 250.
Coming from someone who has done a lot of research but just hopped on, lots of advice to give but need to be more specific:
- Bloodwork: Get bloodwork done before, ~4-6 weeks into cycle, and some weeks afterwards (if you decide to stop and PCT) MINIMUM.
- Injection: Virgin muscles will hurt like a bitch, try and pin a muscle you won't use for a couple days if possible. My schedule personally looks like legs on Thurs and Sunday so I pin quads on Monday to have some time for the PIP to clear.
- Ancillaries: Take other drugs to keep your bloodwork (or really your health, not just the results on a page) in line. You should not be reactionary with all drugs (being that you shouldn't only use them based on feelings). You should have ALL possible ancillaries needed on hand. With that being said, 99% chance you will be fine but it never hurts to do it the right way. If you would like a list of ancillaries you should have on hand AT LEAST: Arimidex/Aromasin (AIs, preferably adex), blood pressure monitor (not a drug but get one), ezetimibe (cholesterol), hcg/hmg (testes fertility/size management), ru/minoxidil (hair loss prevention), nolvadex/raloxifene/tamoxifen (SERMs with anti-gynecomastia activity).
