It seems that up to 600mg EW of test for 10 weeks or so is considered unlikely to have particularly adverse effects ie long term damage to lipids, or your heart or liver health etc. Gyno or acne etc is not considered a long term health risk and is easily managed anyway.

That's probably why 500mg test EW is a recommended starter dose. Bearing in mind that food intake, training intensity and rest are all important there's probably no need to go much higher than that until you absolutely need to.

If you add tren, then the need for test is less, unless you are experienced and have the need to increase the risk to reward ratio. Also, tren sides are lessened with less test. That's how I run test and tren anyway.

Tren is obviously a harsher drug than test but gives a harder less bloated result. It's a trade off. More sides, more chances of long term bad effects but probably better results.
