GRASZ, Circuit Judge.

       In 2012, government investigators identified California resident Ladronal
Hamilton as the source of supply for multiple distributors of phencyclidine (“PCP”)
in Kansas City, Missouri. A grand jury eventually charged Hamilton with conspiracy
to distribute one kilogram or more of PCP in violation of 21 U.S.C. §§ 841(a)(1),
(b)(1)(A), and 846. The case proceeded to trial, where the district court1 denied
Hamilton’s motion for judgment of acquittal before a jury found him guilty. The
district court sentenced Hamilton to a life term of imprisonment based in part on his
significant criminal history and applicable enhancements for, among other things,
maintaining premises for the purpose of distributing PCP, taking a leadership or
organizer role in the conspiracy, and obstructing justice. Hamilton appeals, arguing
there was insufficient evidence to support his conspiracy conviction and that the
sentence enhancement for obstruction of justice was unwarranted. We affirm.

                          I. Sufficiency of the Evidence

       On appeal, Hamilton argues the evidence was insufficient for several reasons,
including: (1) the government’s cooperating witnesses testified against him only in
exchange for their own plea deals or sentence reductions and generally lacked
credibility; (2) there was no evidence Hamilton had anything more than a buyer-seller
relationship with any of the alleged co-conspirators; and (3) the government failed
to establish Hamilton knew boxes he shipped from California to Kansas City actually
contained PCP.2

       Examining the evidence in the light most favorable to the verdict, “[w]e review
de novo the denial of a motion for judgment of acquittal based on the sufficiency of
the evidence.” United States v. Druger, 

, 569 (8th Cir. 2019). We “also

        We note Hamilton filed a supplemental brief on May 1, 2019, focusing on the
second and third reasons. We granted leave to file such a brief after Hamilton’s
original counsel became seriously ill shortly before the case was to be argued and
then passed away soon after the case was submitted on the briefs. Despite Hamilton’s
shift in focus under newly appointed counsel, we address all three reasons for the
sake of completeness.

uphold the jury’s verdict if at least “one theory
based on the evidence presented could allow for a reasonable jury to find [the
defendant] guilty beyond a reasonable doubt.” 

standard applies
even when the conviction rests entirely on circumstantial evidence.” United States
v. Tillman, 

, 833 (8th Cir. 2014) (quoting United States v. Worman, 

, 977 (8th Cir. 2010)).

       “To establish a conspiracy, the government must prove: (1) the existence of an
agreement among two or more people to achieve an illegal purpose, (2) the
defendant’s knowledge of the agreement, and (3) that the defendant knowingly joined
and participated in the agreement.” 

States v. Johnson, 

, 666 (8th Cir. 2013)). “[T]he government ‘need only establish a tacit
understanding between the alleged co-conspirators, which may be shown through
circumstantial evidence.’” 

(quoting United States v. Jackson, 

, 1044 (8th Cir. 2010)). The conspiracy need not be a “discrete, identifiable
organizational structure,” but may rely on “‘a loosely knit, non-hierarchical collection
of persons who engaged in a series of transactions involving distribution-quantities
of [drugs] in and around’ a particular city over a course of time.” United States v.
Conway, 

, 587 (8th Cir. 2014) (quoting United States v. Slagg, 

, 837, 840 (8th Cir. 2011)).

        We reject Hamilton’s argument that the government’s witnesses were not
credible because they were self-interested and dishonest. It is the jury’s prerogative,
not ours, to judge the credibility of witnesses. At trial, five cooperating witnesses
testified against Hamilton. All five informed the jury about any plea agreements and
sentence reductions they received (or hoped to receive) in their own proceedings in
exchange for testifying against Hamilton. Hamilton also notes they all had multiple
prior convictions and several were shown to have previously lied to government

                                          -3-
officials. But “[w]e have repeatedly upheld jury verdicts based solely on the
testimony of conspirators and cooperating witnesses, noting it is within the province
of the jury to make credibility assessments.” United States v. Buckley, 

,
632 (8th Cir. 2008). “Juries are capable of evaluating the credibility of testimony
given in light of the agreements each witness received from the government,”

(quoting 

), including “the promise
of a reduced sentence.” United States v. Velazquez, 

, 1016 (8th Cir.
2005). Therefore, we will not disturb the jury’s credibility assessment of the
government’s witnesses here.

       We also reject Hamilton’s argument the government failed to prove he entered
into anything more than a buyer-seller relationship with any alleged co-conspirator.
Hamilton specifically argues no evidence directly linked him to any PCP distributor
in Kansas City. He notes that at trial, “only one witness testified to a single
transaction directly with Mr. Hamilton,” while the others said they merely believed
Hamilton was their source of PCP. Hamilton points out that law enforcement officers
did not purchase PCP from him in any controlled buys, did not overhear any phone
calls to or from him during numerous wiretaps of alleged co-conspirators’ calls, and
did not discover his phone number on the phones seized from most of the alleged co-
conspirators. However, the totality of evidence easily showed he entered into more
than buyer-seller relationships with other co-conspirators.

       Here, the government introduced evidence Hamilton sold distribution
quantities of PCP to (and with) various co-conspirators in Kansas City over a period
of time. At trial, a Kansas City narcotics officer experienced in undercover drug
deals testified PCP dealers usually purchase the drug in liquid “ounce quantities”
stored in glass or plastic bottles, while users generally purchase one to three
cigarettes dipped in PCP. Co-conspirator George Britton later testified that, on one
occasion in 2011, he purchased six one-ounce jars of PCP directly from Hamilton in
Kansas City — the “single transaction” for which Hamilton acknowledges there was

                                         -4-
direct evidence. This transaction involved a distribution quantity of PCP and tended
to show at least a tacit understanding Britton would resell the PCP in user-quantities,
as Britton indeed said he did. See 

(“[E]vidence is sufficient
to show a conspiracy where drugs are purchased for resale.”). Additionally, co-
conspirator Reginald Thomas testified he observed Hamilton store PCP in metal cans
and that he met with Hamilton several times in Kansas City to distribute PCP
together, purchased PCP directly from Hamilton “many times” in ounce quantities,
and poured PCP from metal cans into jars in Hamilton’s presence for further
distribution in Kansas City.3 And co-conspirator Leelon Williams said that Hamilton,
in four separate transactions in 2015, fronted him half-gallon or gallon quantities of
PCP in Kansas City through Hamilton’s “homegirl,” after which Hamilton would call
Williams directly with account numbers to which payment should be sent once the
PCP was resold.4 Therefore, because “evidence exists that large amounts of drugs
were distributed over an extended period of time, including fronting transactions,
[this was] ample evidence to support a conspiracy.” 

reject Hamilton’s argument there was insufficient evidence he knew
boxes he sent from California to Kansas City contained PCP. Hamilton
acknowledges the government introduced evidence at trial that, from October through
December of 2014, a U.S. Post Office inspector made three separate seizures of
suspicious parcels sent from California addresses to the Kansas City area. The postal


      3
        Hamilton, whose nickname was “Blac,” points to Thomas’s testimony
admitting there was another PCP supplier known as “Black” and thus implies Thomas
may have been confused about his actual source of PCP. But at trial, Thomas
identified Hamilton as the supplier with whom he personally worked, allowing a
reasonable jury to conclude Thomas did not confuse his suppliers.
      4
       Williams was also the one co-conspirator on whose phone investigators
discovered Hamilton’s phone number, as Hamilton admits. Although Hamilton tries
to downplay this fact by arguing Williams was an unnamed co-conspirator, his second
superceding indictment expressly named Williams as a co-conspirator.

inspector obtained consent or warrants to search the parcels and discovered each
contained gallon-sized, ribbed metal cans filled with one kilogram of liquid PCP. A
forensics examiner determined that packing newspaper found in one of the parcels
contained Hamilton’s fingerprints and that exterior packing tape contained the prints
of Hamilton’s girlfriend. In addition, the postal inspector used mailing records to
discover video surveillance from southern California post offices showing Hamilton
mailing each parcel. Still, Hamilton argues his mere physical proximity to what was
discovered to be PCP is not enough to establish his knowledge of the contents of the
boxes. See United States v. Cruz, 

, 697 (8th Cir. 2002). He notes the
boxes were already sealed when he was observed on video carrying them at the post
office and the forensics examiner admitted there was no way of knowing how old the
newspaper fingerprints were. Again, however, we find the totality of evidence easily
showed Hamilton knew what he was shipping.

       This was not a matter of mere proximity. The government introduced an
abundance of circumstantial evidence establishing Hamilton’s knowledge — the
usual method for doing so in this type of case. See United States v. Ojeda, 

, 1476 (8th Cir. 1994). In addition to the circumstantial evidence described
above, at trial the narcotics officer testified that in his experience PCP dealers in
Kansas City are supplied by California sources, who sometimes transfer PCP in
silver, gallon-sized cans. A California police officer later testified that during a 2012
search of Hamilton’s home for a state-law charge of possessing a controlled substance
(cocaine), officers discovered (but did not seize) numerous empty coffee cans and lids
along with cardboard boxes on Hamilton’s front porch. Though Hamilton asserts
coffee cans are “a far different kind of container” than the metal cans discovered in
the parcels, he points to no evidence supporting this argument or precluding a
reasonable jury from believing they were similar. Because we must accept all
reasonable inferences in support of the verdict, 

, this
evidence was clearly sufficient to show Hamilton knew the parcels he sent from
California to Kansas City contained cans of PCP. This evidence also corroborated

                                          -6-
the testimony of the cooperating witnesses, and thus Hamilton’s insufficient-evidence
argument must fail.

                    II. Obstruction of Justice Enhancement

      Hamilton argues a two-point sentence enhancement for obstruction of justice
was unwarranted under U.S. Sentencing Guideline (“U.S.S.G.” or “Guideline”)
§ 3C1.1. The district court applied the enhancement based on threats Hamilton
allegedly directed toward cooperating witnesses, but Hamilton argues his statements
were too ambiguous to be considered intimidating or threatening.

       We hold that even assuming the enhancement was improper, it was harmless
error. See Fed. R. Crim. P. 52(a). The enhancement increased Hamilton’s offense
level under the Guidelines from 44 to 46 points, but the maximum offense level is 43
points. See U.S.S.G. Ch. 5, Pt. A. The Guidelines’ commentary provides that “[a]n
offense level of more than 43 is to be treated as an offense level of 43.” 

Because the Guidelines recommend a life sentence for any defendant with an offense
level of 43, Hamilton’s Guidelines sentence would have been a life term of
imprisonment with or without the enhancement for obstruction of justice. See 

Pt. A. Indeed, at sentencing the district court acknowledged Hamilton’s total
offense level was above the maximum and thus calculated his sentencing range based
on an offense level of 43, not 46. Contrary to Hamilton’s argument on appeal, then,
the district court’s calculation of his Guidelines sentence was correct even assuming
the obstruction of justice enhancement was erroneous. Cf. United States v. Durham,

, 1236–37 n.45 (10th Cir. 2018) (noting two-level enhancement for
obstruction of justice “had no effect on the recommended Guidelines sentence” when
defendant’s offense level “already exceeded the maximum offense level of 43”).

      However, even if the district court miscalculated Hamilton’s Guidelines
sentence, we have said this, too, is harmless error “when the district court indicates

                                         -7-
it would have alternatively imposed the same sentence even if a lower guideline range
applied.” United States v. Dace, 

, 1069 (8th Cir. 2016) (quoting United
States v. Martinez, 

, 988–89 (8th Cir. 2016)). Here the district court said
that, based on the sentencing factors of 18 U.S.C. § 3553(a), it would have imposed
a term of life imprisonment “regardless of the calculation of the sentencing
guidelines.” Accordingly, we find it “clear that the judge [also] based the sentence
. . . on factors independent of the Guidelines” and thus any miscalculation of
Hamilton’s Guidelines sentence was harmless. 

States v. Molina-
Martinez, 

, 1346–47 (2016)).

         Therefore, Hamilton’s challenge to his obstruction of justice enhancement also
fails.

                                    III. Conclusion

         For the foregoing reasons, we affirm the judgment of the district court.
