    Testosterone propionate for TRT

    If I had no side effects I would almost definetly cruise relaxed on a long ester, propably even undecanoate. Doing a shot every 2-3 weeks an be good to go. Even E3D on Enanthate I would be very happy with. It's just not happening for me. I think prop is a great solution for people who have...

    Testosterone propionate for TRT

    I think it's as with other medicine, some people just not doing well with certain agents, fillers, oils.... Cannot force it. I had the same tingling fingers and blood pressure problems with one UGL brand a couple years ago. Then one indian pharmagrade brand gave me bad anxiety and skin...

    Testosterone propionate for TRT

    This depends highly on the prop you use. Some brands sting like a bee and leave a huge red lump, others work just fine without sting or swelling (unigen prop for example). From the results I personally feel better with IM, could never make SubQ work for me. The reports about prop and pip come...

    Yes, I agree. I'm not an expert on HCG. I tested it and got nasty side effects. Even without the side effects, injecting a female pregnancy hormone year round would be nothing I want to do. The only way I could imagine doing it, for fertility reasons, would be a big blast maybe every 4-6...

    Yes I have tried this. Prop beats the long esters on same frequent injection protocol by a long shot. I don't know if I'm extra sensitive to the long esters, but especially cypionate creates big problems for me even in tiny amounts. It's like injecting side effects. I do not understand what...

    In the past when I needed an AI to combat side effects it was from (i) long esters (ii) infrequent injections (iii) HCG (iv) DHEA (vi) too much body fat. I feel best with frequent injections with short ester and nothing else. I neither take AI, nor HCG, nor DHEA, nor Pregnenolone anymore...

    Testosterone propionate for TRT

    Thinking a bit more about it, the positive response to prop could as well have something to do with my metabolism. When i use prop, I instantly get hungry. All I want to do is eat, drink coffee, train and work. Never getting this response with longer esters. On prop it's impossible not to...

    Testosterone propionate for TRT

    Tested them all during the last 4-5 years. - Suspension - Propionate - Phenylpropionate - Enanthate - Cypionate - Undecanoate - Sustanon Propionate is the winner for me, not even close. Drive, aggression, focus, energy. Suspension is nice as well, but hits too hard / fast for my liking. All...

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
