When should I check bloods?

I love how members help each other here. This forum was set up to hold SOURCES to account — reviews, SI chats, and threads are where we find out who’s selling the best and safest gear/HGH. Anyone who’s been around knows there are fakes on both sides, and sometimes they collude to convince people everything is perfect. So how do we verify for OURSELVES? 1) Learn to read forums and SI pages and spot who’s reliable. 2) BLOODS, BLOODS, BLOODS!! You can’t argue with lab results. Your body responds in a unique, measurable way. Getting optimal growth means knowing your training, nutrition, and bloods — estradiol, prolactin, RBCs, liver, kidneys, etc. BUT WHEN DO WE TEST? For Enanthate/Cypionate the vets tend to recommend mid-to-late week 4. Not bro-science — actual pharmacokinetics. Doctors prescribing TRT often ask patients to come back in 4 weeks to check and adjust, but rarely explain why. So let’s look at prior posts backed by science: day 28 (week 4) is nearly at maximum concentration, day 35 is roughly peak. Mid-week 4 puts you close to peak levels. Yes it rises a bit by day 35 (week 5), but we’re not only chasing peaks. A full blood panel gives totals, which is what we want, plus e2 and the bigger picture for maximizing growth. Short esters are a whole other debate…
