Sinkewitz scored a 24/1 T/E using a satchet , Kessler got it up to 85/1 with Andriol  - yet both drugs are much less potent than some injection. So bottom line is, it worked, it has always worked as intended.The problem with Testogel is that it’s an incredibly inefficient means of delivering synthetic testosterone, so the 50mg sachet will only be good for a fraction of that dose when absorbed into the body.
Intramuscular injections are the only efficient means of delivery for true performance enhancement.
In any dose Testogel is pretty much useless for enhancing strength, speed, muscle development etc
What Testogel does do is provide enough of a dose when applied daily to restore depleted levels in individuals (wether that depletion is age related or from the inevitable decline experienced by athletes during heavy endurance training blocks) back to ‘normal’ ranges. Hence it’s historic use in cycling I think.
So to answer the question, 30 x 50mg sachets really is a very minimal level for one individual for a month to see any benefit at all. ‘Microdosing’ with anything less would be pretty pointless ime.
Both ratios are also lower than the probability that this was the first and only order of T by anyone from Sky/British Cycling.
