Test E

Welcome to the gain train at 58, but at that age, expect some solid energy and recovery boosts around week 3 or 4—just keep an eye on that swelling, as persistent "PIP" (post-injection pain) might mean you need to switch up your technique or site.

At 58 I’d focus more on health markers than quick results. Don’t expect much in the first couple of weeks, it usually takes time to feel noticeable changes. If the swelling goes down and there’s no redness or heat, that’s generally a better sign.

Slow and steady is the smart way to go.

At 300mg / week (I asssume it's 300mg/ml potency as you say it's test E) you'll almost certainly suffer from high oestrogen side effects (limp d1ck, lack of masculine calm, water retention and high blood pressure). The dose is way too high to not use oestrogen control for most people. Consider having Aromasin on hand for this. Have a search for starting dosages but ideally you'll be guided by E2 on your bloodwork (middle of the lab's reference range is going to work well for almost everone). I'd try 12.5mg / week perhaps broken into 2 doses, each taken the day after your injection.

Do keep us posted!
