Ok I feel obligated to chime back in. There were some valid but tough points made to the OP.
I don’t like advising someone else on what they should do. I would rather critique a plan someone laid out, and most of us on here are very similar with that out look. It’s just all to easy to give advice without knowing all the facts and accidentally guide someone into hurting themselves.
To the OP, GET SOME TESTOSTERONE! Yes EQ is a test based hormone as in they took the test molecule and modified it slightly but it does not take the place of testosterone. Your body needs testosterone. Any ester will do as long as it is testosterone. I would say the easiest for you would be cypionate or enanthate. We can discuss dosage after you decide on a few things.
Since you are getting some test you might as well get some more EQ, enough to get the per week dosage up to 300-400. 300 is pretty low but given that this is first cycle and you will be also having test in there the final dosage is up to you.
Also again running EQ for less than 12 weeks is almost waisting it and it should be up to 15.
As far as how much test to get. Trt levels are around 100 mgs per week and up. Since you have EQ already in the mix most guys like a 1 to 1 ratio of EQ to test. If you run 300 of each then you are up to 600 mgs total and usually first cycles can be around 500mgs of test per week so you would be in the ball park. You should get enough test to at least run it 2 weeks past the time you stop the EQ. They have different esters and you can start PCT until the long EQ clears your system so running the test two past keeps enough test in your system as you wait on the EQ.
Again your body needs test and given age if you go 10 week’s of no test some stuff could turn off and not turn back on. Like erections, do I need to say more?
For PCT get enough Nolvadex for taking 40 mgs a day for two weeks then 20 mgs a day for two weeks.
You should also think about getting arimidex or aromasin just in case you have on cycle estrogen issues.
The compounds I listed are trade names so expect everything to be in pharmaceutical names, you need to search the names.
Your buddy given his age probably never bothered to learn about PCT. When he started using he was probably young, they didn’t really have access to PCT drugs then.
As far as you locating sources for this stuff. Your buddy might not even get Nolvadex. There are other sites like this one that have reviews for sources. Really most sources are going to most likely be ok because they want repeat business. Now over all quality and proper dosing varies. But you at the very least NEED Nolvadex so you are going to have to explore. Just FYI those shipping promises of next day shipment are ALL bs. They usually take up to a week to get out. Depending on method of shipment expect about a week of sitting in origin country then a couple of days of moving then a couple of days getting through customs. You could always look for a domestic source and avoid customs but you will pay more. Just FYI even if it is domestic expect to wire money to eastern Europe or china for payment. The domestic sources are usually good to get the stuff out in 2-3 days then 2-3 days travel time.
