Running mast e at 400mg for the first time - week 6 update

Running mast e at 400mg for the first time alongside 500mg test e. Week 6. What changed: hardening is visible, libido is noticeably up, skin is drier. What has not changed: strength. Never expected it to be a strength compound but worth noting. Body fat was around 13% going in. Mast responds much better when lean and 13% is probably the minimum. Worth running if your body fat is in that range.

Mast works best when ye're lean as you said. Ran it at 15% body fat once and barely noticed anything. Ran it at 11% and it felt like a completely different compound. The hardening effect is real but body fat dependent. At 13% you should get good results by week 8-10.

Good write-up. The libido effect from mast is real and reliable for me every time. SHBG binding is the mechanism and it shows in practice. One thing to watch at 400mg alongside test - hair. DHT derivative will accelerate shedding if you have any genetic predisposition there.

The absence of strength increase is expected and worth flagging for anyone newer to mast. It is a cosmetic and finishing compound. Hardening, drying out, libido improvement - those are the mechanisms. Running it for size or strength gains would be a waste of money. At 400mg alongside 500mg test the synergy for body composition at low body fat is well established.

When you say the hardening is visible at week 6, can you be more specific? Is it mainly the midsection or across the whole physique? Trying to understand at what body fat percentage this would actually be noticeable to someone else looking at you.
