If you’re doing one injection each week then the test cyp will reach it’s highest TT at 3-4 days and highest FT and BioT at 5-6 days post IM injection, E2 peaks somewhere in that latter range, SHGB elevates over 3 months consistent T use and should remain at that level for the duration of TRT. thereafter. All values for Testosterone should be around or even below 300-400 by day 10-12 post last IM injection but this isn’t always what your labs will show as you can expect something close to 100 points swing in one way, or the other just by the nature of these tests, which are not meant to be precise beyond their current level for their usual scope of use. I would just delay your appointment if you can, and for sake of being on TRT delay it for quite a bit if you can stomach that to find out what your actual recovered normal levels are, if you in fact, are approaching TRT for that purpose if you are just searching for doctor, prescribed testosterone you could play it as close to you with tolerance as you feel necessary, but also do not have any biotin for at least a week before the test and then claim that you took 5000 mg for the previous month or two as a hair and skin and nail supplement, or whatever. If it comes back elevated by often can interfere with most assays and nearly guaranteed to mess up most of your immunological and endocrine panel, standard hormone values in one direction or another.

Testosterone will show high elevation erroneously, even with a few days or more of wash out from biotin supplementation. It’s not the greatest plan of attack here, but it’s the most scientifically viable explanation for you to act incredulous about why you might hit above the detectable ceiling if you go get tested fairly soon. Then you can research and send the FDA warnings and industry articles grappling with this issue. That’ll buy you another week or two to come back and retest when you think your levels are where you want them. If you are not using any biotin don’t start, and the retest results will show your T levels as can be expected to continue to decline per the pharmacokinetics outlined reasonably specifically as above for most men using cypionate ester.

You can also try to eat tons of food and sugars that lmorning before your test, it reduce your values for testosterone pretty significantly, but not to the degree biotin will interfere; with the additional benefit of the manufacturer listing biotin interactions and noting that interference is a possibility that technicians rarely ever read or add to the narrative, nor do they ask physicians if it’s a factor.

Typically on that dose you would wait 18 days before starting PCT. That is about when the test levels are in about the so called normal range and not elevated so therefore PCT can begin. If you need 200mg/wk for TRT, you are an outlier as far as metabolizing test though so I really have no clue how long you should wait. Best to get some bloodwork or better yet don't do a blast before you are scheduled to see your doc.

About 3 weeks. Cyp has a half life of around 8 days, so as long as you stop injections for a minute, it’ll take 18-21 days, typically.
