Np. Transdermal application usually has a half-life of 12 hours or so. Someone as serious as you should def consider splitting your dose over a twice/day application. Guys that were on TRT at 150 or 200mg of cyp/wk said that 50mg/day transdermal of Trestolone (350mg/wk) felt decidedly better than their prescribed script. Better pumps, better workouts (it is about twice the mg/wk, after all). Trestolone is one of the only compounds besides Test that still allows all normal healthy & sexual functions in an environment devoid of testosterone over an extended period. It shuts you down just as fast as nandrolone (not an issue for you) but actually gives awesome sexual performance apparently. Rub it on your shoulders, traps, neck, insides of your arms, can even rotate your legs & behind the knees, anywhere skin is thin absorbs well. Clean skin obv preferred, let it dry before you throw your shirt on. If it's anything like the TD's I've tried, it's about 30 seconds after rubbing it on your g2g. I used to know a UGL supplier, & he sold transdermal apps including trest ace when PHF released the raw powder. Said that T/D users experienced at least 1/3 of the effect, mg/mg, compared to IM. Maybe as much as half. Very good absorption. He said IM is just downright awesome, 50-100mg/day of trest ace is what you see blasted IM. But he said the transdermal is being received really well. He sold through his stock a few times before I lost contact with him. I imagine there's logs on PHF if you wanna read firsthand stuff on Trestoderm & the raw trest ace powders, & there's a little discussion in the Celtic Labs section here under Supplement Companies. Olympus Labs has good pricing on oral capped trest, & you'd only need 75-100mg (3-4 caps)/day, but it's useless for a cruise because the oral only has a 3-4 hour half-life. Lastly, beware: trest seems to aromatize quite hard. You will need to be on your game to control gyno with it. That's really the only downside, cost is on the higher end & the methyl-estradiol it can aromatize to is nothing to dismiss. But as a cruise that seems to be quite manageable; it's the IM blasting that can be tricky.
