This is on the money. You need to reconsider your plan. Just because you bought the "test 500" does not mean you have to use it right now. Your trainer doesn't know shit about AAS if he is telling you to run that for 6 week.
Tazzzzzz, listen to us. We are gear heads. Collectively we've run hundreds of cycles, we know what we are talking about. Keep the compounds you've purchased. You can always use them later. I have enough test e, c, p and orals in my safe to keep me on cycle for a year. Just because I have it doesn't mean I need to use it all right now.
Reconsider your cycle. If you want a short cycle, 150 mg of testosterone propionate for 6-8 weeks is fine, although the PIP (post injection pain) from prop on your first cycle may be crippling. If you want the typical and PREFERRED first cycle, get enough testosterone enanthate or cypionate (they are essentially interchangeable) to run 10-12 weeks at 500 mg a week.
On a related note, your winny in water-based, testosterone is in oil. Mixing the two in a syringe will make a two phase mixture, and generally sounds painful and like a bad idea. Pin water-based and oil-based compounds separately.
For a short 6-8 week testosterone-only cycle, nolvadex alone may be sufficient, run 40/40/20/20 for four weeks. That's 40 mg a day for the first 2 weeks, 20 mg a days for the last two weeks. For a longer cycle, you may need to add either clomid or torem, and HCG on cycle may be a good idea to keep your balls working.
Please do some reading, and reconsider your 6 week "test 500" cycle, it will not so what you want it to do, but it will shut you down for ages.
